根据自己的需要可以将TEXMFHOME目录设置成不同的地方,只要Latex能找到即可
我将该目录改为了/usr/share/texmf-tetex,如果相应的目录不存在,则需要自己新建。


将windows系统中的字体文件拷到脚本所在目录执行脚本即可生成Latex所需字体文件,以simhei.ttf为例:

sudo ./cvtfont.sh simhei.ttf simhei simhei

Ubuntu下NVIDIA驱动的问题

前几天按照Ubuntu How-To上的NVIDIA驱动安装说明安装了8672版的驱动,结果发现只要退出X-Window,系统就会没有反应,网上搜了搜,发现有人也有一样的情况,按照说明重新安装、重新配置Xorg,问题依然没有解决,X-Window也起不来了。

到NVIDIA网站上下了最新的8774版驱动后,赶紧找找看怎么自己装,有人已经写好了
在恢复模式下:
需要gcc支持,如果没有安装则:
apt-get install build-essential gcc
删除已经安装的NVIDIA驱动:
apt-get --purge remove linux-restricted-modules-`uname -r` linux-restricted-modules-common nvidia-glx nvidia-settings nvidia-kernel-common
安装内核headers
apt-get install linux-headers-`uname -r`
将下载下来的NVIDIA-Linux-x86-1.0-8774-pkg1.run解压缩:
sh ./NVIDIA-Linux-x86-1.0-8774-pkg1.run --extract-only
进入解压后的NVIDIA-Linux-x86-1.0-8774-pkg1文件夹,执行安装:
./nvidia-installer -n --x-prefix=/usr/lib/xorg/
最后由于默认安装到了/usr/lib/xorg/lig/xorg,需要将文件拷到对应的目录下:
cp --no-dereference /usr/lib/xorg/lib/xorg/libX* /usr/lib/xorg/modules/

cp /usr/lib/xorg/lib/xorg/modules/drivers/* /usr/lib/xorg/modules/drivers/

cp --no-dereference /usr/lib/xorg/lib/xorg/modules/extensions/* /usr/lib/xorg/modules/extensions/

Qt 4下连接MySQL数据库

前天刚装了个Qt4for windows,发现安装的时候MySQL等数据库插件都没有安装,像Qt X11版一样,都需要自己安装这些插件。

在Qt的安装目录C:\Qt4.1.2\下,有个src目录,进入plugins\sqldrivers\mysql,可以看到两个文件,main.cpp和mysql.pro,很显然要用qmake来完成编译、生成目标。

编译前,首先保证依赖的MySQL头文件和库文件正确。首先MySQL安装目录下的include中的所有文件拷到qmake时能找到的目录下,接着从lib/opt目录下拷出libmysql.a,其实lib/opt下只有libmysql.lib和libmysql.dll,从网上搜了一下找到一个方法从libmysql.dll生成libmysql.a:

1 、安装好MySQL (如果不愿意安装,找个libmySQL.dll文件也可以)

2、下载Pexports工具

3、转换操作: pexports libmysql.dll > libmysql.def

4、使用MinGW的 dlltool转换成为libmysql.a文件。dlltool --input-def libmysql.def --dllname libmysql.dll --output-lib libmysql.a -k

5、尝试是否成功:
将生成的libmysql.a 拷到qmake的lib搜索路径下后在plugins\sqldrivers\mysql目录下做:
qmake -project
qmake
make

如果再出现象mysql_connect@xx (xx是数字)的错误提示。就执行第6步。

6、修改libmysql.def文件,给mysql_connect加上@xx,即mysql_connect@xx

7、重做第4步

8、然后尝试第5步,如果还是出现错误提示。就作第6步。一直到没有错误为止。

最后C:\Qt4.1.2\plugins\sqldrivers下将会生成需要的libqsqlmysql.a和qsqlmysql.dll。

找了一个测试文件,通过。
#include <QtSql> 
#include <QtGui> 


bool createConnection(){ 
QSqlDatabase db 
= QSqlDatabase::addDatabase("QMYSQL"); 
db.setHostName("localhost"); 
db.setDatabaseName("test"); 
db.setUserName("test"); 
db.setPassword(""); 

if(!db.open()){ 
QMessageBox::critical(
0, QObject::tr("Database Error"), 
                              db.lastError().text())
; 

return false
; 


QSqlQuery query
; 
//query.exec("insert into book values( 3, 'title', 'author') "); 
query.exec("select title , author from book "); 

while (query.next()) { 


    QString title 
= query.value(0).toString(); 
    QString author = query.value(1).toString(); 

QMessageBox::critical(
0, title,author); 
    



return true
; 




int main(int argc
,char** argv){ 

QApplication app(argc
, argv); 
    if (!createConnection()){ 

return 
1; 

        

    return app.exec()
;

SSH(Spring + Struts + Hibernate)小试 之三

SSH(Spring + Struts + Hibernate)小试 之三


前面通过PlugIn我们实现了Spring Context的加载,不过仅仅加载Context并没有什么实际
意义,我们还需要修改配置,将Struts Action交给Spring容器进行管理。下面将通过一个Regsit
实例加以说明。

首先准备好regist.jsp和login.jsp,在regist.jsp中 的form有name,password,password2,email域。

在struts-config.xml中添加配置:

<form-bean name="registForm" type="com.lzy.forum.form.RegistForm" />

<action path="/regist" name="registForm"
type="org.springframework.web.struts.DelegatingActionProxy"

validate="true" input="/regist.jsp" scope="request">
<forward name="failure" path="/regist.jsp" />
<forward name="success" path="/login.jsp" />
</action>


RegistForm,RegistAction按照原来Struts的方法去写,我在RegistAction中加入了一个UserDAO对象
userDAO,这个对象由Spring注入。

<bean name="/regist" class="com.lzy.forum.action.RegistAction"
singleton="false">
<property name="userDAO">
<ref local="userDAO" />
</property>
</bean>

基本上SSH的架构已经完成,经确认后可以自己测试一下了。(完)

SSH(Spring + Struts + Hibernate)小试 之二

Spring和Struts结合有几种方法,我选了最常用的PlugIn方式,在struts-config.xml中加入

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
      <set-property property="contextConfigLocation"
            value="/WEB-INF/action-servlet.xml" />
 </plug-in>

WEB-INF目录下的action-servlet.xml就是Spring的配置文件,下面给出的是整个的action-servlet.xml文件:

</beans>

经过这样的配置之后,Hibernate事务交由Spring管理,sessionFactory从Spring容器获得。下面通过其中的一个DAO实例来看看这样做带来的方便。


//BoardDAO.java

package com.lzy.forum.dao;

import java.util.ArrayList;

import com.lzy.forum.domain.Board;

public interface BoardDAO {
 
 public boolean isBoardExist(String name);
 
 public void addBoard(Board board);
 
 public void deleteBoard(Board board);
 
 public Board loadBoard(int id);
 
 public Board loadBoard(String name);
 
 public Board loadBoardWithArticles(int id);
 
 public ArrayList getRootBoardsList();
 
 
 
}


//BoardDAOHibernate.java

import java.util.ArrayList;
import java.util.Iterator;
import java.util.ListIterator;
import java.util.Set;

import org.hibernate.Hibernate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.lzy.forum.dao.BoardDAO;
import com.lzy.forum.domain.Board;

public class BoardDAOHibernate extends HibernateDaoSupport implements BoardDAO {

 public void deleteBoard(Board board) {
  // TODO Auto-generated method stub
  this.getHibernateTemplate().delete(board);
 }

 public void addBoard(Board board) {
  // TODO Auto-generated method stub
  this.getHibernateTemplate().saveOrUpdate(board);

 }

 public boolean isBoardExist(String name) {
  // TODO Auto-generated method stub
  ArrayList list = (ArrayList) this.getHibernateTemplate().find(
    "from Board where name = ? ", new Object[] { name });
  if (list.size() > 0) {
   // System.out.println("find it");
   return true;
  }
  return false;
 }

 public Board loadBoard(int id) {
  // TODO Auto-generated method stub
  ArrayList list = (ArrayList) this.getHibernateTemplate().find(
    "from Board where id = ? ", new Object[] { id });

  Board b = null;
  if (list.size() > 0) {
   b = (Board) list.get(0);
  }

  return b;
 }

 public Board loadBoard(String name) {
  // TODO Auto-generated method stub
  ArrayList list = (ArrayList) this.getHibernateTemplate().find(
    "from Board where name = ? ", new Object[] { name });

  Board b = null;
  if (list.size() > 0) {
   b = (Board) list.get(0);
  }

  return b;
 }

 public ArrayList getRootBoardsList() {
  // TODO Auto-generated method stub
  ArrayList list = (ArrayList) this.getHibernateTemplate().find(
    "from Board b left join fetch b.ChildBoards where b.Parent = null order by b.id");
  System.out.println(list.size() + " root boards found ");
  

  ListIterator index = list.listIterator();
  while (index.hasNext()) {

   Board s = (Board) index.next();
   //this.getSession(true);
   //Hibernate.initialize(s.getChildBoards());
   ///*
    Set children  = (Set) s.getChildBoards();
    Iterator it = children.iterator();
   
    while(it.hasNext()){
    Board b = (Board)it.next();
    //Hibernate.initialize(b);
    System.out.println(b.getName());
    }
    //*/

   //System.out.println(children.size() + "child(ren) found ");
   //s.setChildBoards(s.getChildBoards());
  }

  return list;
 }

 public Board loadBoardWithArticles(int id) {
  // TODO Auto-generated method stub
  ArrayList list = (ArrayList) this.getHibernateTemplate().find(
    "from Board b left join fetch b.Articles where b.Id = ? ", new Object[] { id });

  Board b = null;
  if (list.size() > 0) {
   b = (Board) list.get(0);
  }

  return b;

 }


}


BoardDAOHibernate继承 HibernateDaoSupport后,通过getHibernateTemplate()得到一个HibernateTemplate实例,然后执行CRUD操作,非常简单。需要注意的是,由于执行一次CRUD操作后,Hibernate session关闭,如果有使用延迟加载策略的对象没有加载,在后面的Web层很容易出现如下错误:
failed to lazily initialize a collection of role
从网上搜到的解决方法是Open Session In View,
<filter>
     <filter-name>hibernateFilter</filter-name>
     <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
     </filter-class>

     <!-- singleSession默认为true,若设为false则等于没用OpenSessionInView -->
    <init-param>
       <param-name>singleSession</param-name>
       <param-value>true</param-value>
    </init-param>
  </filter>

   <filter-mapping>
     <filter-name>hibernateFilter</filter-name>
     <url-pattern>*.do</url-pattern>
   </filter-mapping>
我试了试,还是有一些问题,所以后来还是放弃了这种方法,所有在Web层中需要的对象都必须在Business层中加载完成。如下面的代码所示:

ArrayList list = (ArrayList) this.getHibernateTemplate().find(
    "from Board b left join fetch b.Articles where b.Id = ? ", new Object[] { id });


这样Hibernate和Spring的结合也算完成了。其他的一些DAO类和实现代码我没有给出,但是大同小异,和Board的实现类似。


最后将是Struts 和Spring的结合,将在下一篇给出。(未完待续)

SSH(Spring + Struts + Hibernate)小试 之一

之前对Spring Struts Hibernate都稍有了解,Spring的IOC给我留下了很深的印象,容器管理的对象生成
方法极大地简化了程序逻辑,Spring也提供了用于Web的Spring MVC 框架,由于我感觉其易用性还是不及
Struts,所以我还是选择Struts作为前端WEB框架,Hibernate我一直没有在Web应用中试过,这次当然不会
错过机会了。


开发环境的塔建我就不多说了,具体可以参考我以前的几篇日志。

在Eclipse中新建一个动态Web工程,将Struts 、Spring、Hibernate需要的jar都添加到WEB-INF/lib目录下,
将Struts标签所需的tld文件、struts-config.xml文件(可以由StrutsIDE生成)添加到WEB-INF下,另外在
此目录下添加一个Spring的配置文件applicationContext.xml。


我参考的例子是夏昕的《深入浅出Hibernate》上的第6章,很好的一个论坛示例。

首先按照书上的ER模型,在数据库(MySQL)中建立相应的数据库。


create database forum;

use forum;

create table user(
 id int not null auto_increment primary key,
 name varchar(50),
 pwd varchar(50),
 email varchar(50)

)type=innodb;


create table board(
 id int not null auto_increment primary key, 
 parent_id int,
 create_by int not null,
 name varchar(50) not null,
 remark varchar(255),
 create_time datetime,

)type=innodb;

之后,我选择了用Hibernate Sychonizer来生成映射文件和实体类,然后对生成的类进行修改(删掉了生成的Base类),
实际上Hibernate Sychonizer生成的映射文件也有错误,需要修改,我也是后来在使用中发现的。

Eclipse + CDT + MinGW 下编写QT程序


环境:
(1)安装Eclipse + CDT + MinGW
(2)安装QT for Windows
(3)安装QT plugin for Eclipse :org.eclipse.qt-1.0.2.zip,在Preference里设好相关路径。

新建一个 QT project,将hello。cpp复制到工程中:
#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv[]){
 
 QApplication app(argc, argv);
 
 QPushButton hello("Hello world!");
 
 hello.resize(100, 30);
 hello.show();
 
 return app.exec();
}

build后生成Makefile,新建两个Make Target:all,clean
Make all 后发现找不到libQtCored4.a等文件,在QT的lib目录下找到相应的libQtCore4.a,复制后重命名为libQtCored4.a,
其他库文件类似,最后编译通过,运行后出现带hello按钮的窗口。

Eclipse + CDT + MinGW 下编写OpenGL程序


Eclipse + CDT + MinGW环境的搭建比较简单,由于机器内存不够大,我在preference里将C++的indexer都置为NO INDEXER。
安装MinGW后可以看到,在Include和Lib目录下有了与OpenGL相关的头文件和静态库。为了使用GLUT,我将glut.h放到了相应的
GL目录下,看到Lib目录下有libglut.a库文件,我没有将glut。lib放进去(后来发现libglut。a好像在windows不可用)。

新建一个Standtart Make C++ project,将原来可运行的OpenGL程序复制过来,写好Makefile,结果编译的时候还是出现错误。
还好找到了这个非常有用的网页:http://www.mingw.org/MinGWiki/index.php/Glut
按照上面列出的错误,我在每个#include<GL/glut.h>前都加上#define _STDCALL_SUPPORTED,然后又将glut32。lib、
opengl32.lib、glu32.lib都放到当前的工程目录下,用”glut32。lib opengl32.lib glu32.lib“ 代替原来的 ”-lglut -lopengl32 -lglu32",
最后终于编译通过。

JavaScript和Applet互相调用

Java Script 调用 java 可以在网页里使用

<script language=javascript>

       document.applet_name.method_name();

</script>

可以对 applet 进行控制,也可以从 applet 返回值。

 

 

Java 调用 Java Script

需要导入 netscape.javascript.jsobject 这个类 (jre/lib/plugin.jar)

比如:

JSObject window=JSObject.getWindow(this);

JSObject window=(JSObject)window.getMember("document");

来获取对当前窗口的控制权。

 

当点击链接 MakeCall 时,会触发 Java Script 函数

 

function makeCall(s){

  window.document.ctiApplet.testJavascript(s);

  alert("call maked!");

 }

 

在这个 Java Script 函数中, ctiApplet 是一个 Applet ,这样完成了 java script 调用

Applet

以下是 ctiApplet 中的 testJavascript 函数和运行结果,其中又调用了 Java Script
public void testJavascript(String msg){

      

 

       try {

              // create JSObject

 

                  JSObject.getWindow (this).eval ("javascript:alert('Java Script in Applet!')") ;

       }

       catch (Exception ex) {

              // Error on create JSObject

                  showStatus( "Error call javascript err=" + ex );

       }

 

       System.out.println(msg);

}

EJB 3.0 学习笔记——准备工作


在开发EJB3.0 之前,首先应该去下载它的一个实现和一个相应的支持EJB3的服务器,我下载的是jboss-EJB-3.0_RC5-PFD和JBoss 4.0.3SP1 ,jboss-EJB-3.0_RC5-PFD里面有安装说明和一些不错的tutorial。

根据安装说明,JBoss 4.0.3SP1中的EJB3实现不是最新的,应用下载的jboss-EJB-3.0_RC5-PFD中的一些包去替换。

将jboss-EJB-3.0_RC5-PFD中lib目录下的
 (1)ejb3.deployer/
 (2)ejb3-clustered-sfsbcache-service.xml
 (3)ejb3-interceptors-aop.xml
 (4)jboss-aop-jdk50.deployer/
拷贝到jboss-4.0.3SP1/server/all/deploy目录下

将jboss-EJB-3.0_RC5-PFD中lib目录下的
 (5)jboss-remoting.jar
 (6)jboss-serialization.jar
 (7)jboss-j2ee.jar
拷贝到jboss-4.0.3SP1/server/all/lib目录下


删除jboss-4.0.3SP1/server/all/lib 下的
 (1)ejb3-persistence.jar
 (2)hibernate3.jar
 (3)hibernate-annotations.jar
 (4)hibernate-entitymanager.jar
和jboss-4.0.3SP1/server/all/deploy下的
 (5)jboss-aop.deployer/
到此EJB3 的运行环境准备好了,你可以用jboss-4.0.3SP1\bin\run -c all 测试JBoss是否能成功启动。

我用的IDE是Eclipse 3.2,JDK 1.5 ,为了方便在Eclipse中新建一个User Library:EJB3_JBoss,
将jboss-EJB-3.0_RC5-PFD\lib下的
 jboss-j2ee.jar
和jboss-EJB-3.0_RC5-PFD\lib\ejb3.deployer下的
 ejb3-persistence.jar
 jboss-ejb3x.jar
 jboss-ejb3.jar
 jboss-annotations-ejb3.jar
 hibernate3.jar
 hibernate-annotations.jar
 hibernate-entitymanager.jar
添加到EJB_JBoss中,现在环境基本上搭好了。

FreeBSD 5.3 中的声卡问题



在FreeBSD 5.x中,kernel配置文件的设备名改为sound,不是FreeBSD 4.x中的pcm了,以后还有可能改为snd。


#cd /usr/src/sys/i386/conf/
#make LINT
可生成LINT文件,将kernel配置里的项全部列出了。


在kernel配置文件里加上
device sound
device snd_foo 或
device "snd_foo" <----注意这里foo表示不同的声卡种类,可参考LINT文件。


如果不知道你的声卡应该用哪一个,可以先用
#kldload snd_driver 将所有常用的声卡驱动装载,然后用


#cat /dev/sndstat 察看是否有相应的声卡信息,如:
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: at io 0xd800, 0xdc80 irq 5 bufsz 16384
kld snd_ich (1p/2r/0v channels duplex default)


这里snd_inc就是对应的应该装载的设备。


注意如果对应的声卡种类中有数字,就应该加上引号。


这样重新编译内核就可以了。当然如果不编译内核,用load module的方式也可以。



那么我的问题是什么呢? 我用
#dmesg|grep pcm 能察看到声卡信息。
用 #cat /dev/sndstat 也能看到正确的声卡信息。
并且能够播放CD,但是使用xmms等软件播放mp3文件的时候,播放条根本不走。而后从dmesg可看到如下信息:


pcm0:play:0: play interrupt timeout, channel dead


经过Google查询,怀疑问题出在系统ICQ冲突上。最后,在启动FreeBSD 5.3时,选择了ACPI Disable,就能够正确地用xmms播放了。


最后补充以下,我的机器安装了两块网卡,一块SCSI卡。使用的是版载声卡。怎么解决在ACPI情况下使用还不清楚。但问题基本确定的确是ICQ资源的问题。

FreeBSD安装问题及汉化

五一这几天没事闲的装了FreeBSD,时间可没少花,问题却还是不少,也许对系统还不是太熟悉吧.

1.USB鼠标的问题

第一次装的时候,测试鼠标的时候没动静,不知当时是不是鼠标没插好
只好用PS/2口了,后来编译了一遍内核,USB才能用.

然而最后一次装的时候,USB口可以用,但是startx进入KDE的时候总是失败,找不到什么Pointer,将鼠标插入
PS/2口后重启,上述现象又没了,感觉很是奇怪,进入kde后将鼠标插入USB口也正常.

2..xinitrc文件的问题

第一次装的时候是按照书上装的,当时把xinitrc文件复制过来

cp /usr/X11R6/lib/X11/xinitrc/xinitrc /root/.xinitrc

3.中文字体和输入法



首先安装cvsup,更新ports,然后安装kde-zh******,之后就可以看到kde的一些界面已经中文化了,但是还是有乱码,弄个中文字体过来就可以了

将windows中的simsun.ttc改名为simsun.ttf后复制到/usr/X11R6/lib/X11/fonts/TTF中,然后运行命令

fc-cache -f -v就可以了

中文输入法很简单.fcitx,不过以前装的时候没有更新ports时好象不行.

JSP 处理MySQL数据库时的中文问题

以前遇到JSP 处理MySQL数据库时的中文问题时,采取的是很笨的一种方法,直接用字符串编码转换函数进行转换,这次从网上搜了一下,找到了一个使用Filter的可行方法。在Tomcat 5.5+ MySQL4.0.16下通过。

filter类源码是从网上找的,如下
/**
 *
 */
package com.lzy;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
 * @author lzy
 *
 */
public class SetCharacterEncodingFilter implements Filter {
 
 protected String encoding = null;
    protected FilterConfig filterConfig = null;
    protected boolean ignore = true;


 /* (non-Javadoc)
  * @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
  */
 public void init(FilterConfig filterConfig) throws ServletException {
  // TODO Auto-generated method stub
  this.filterConfig = filterConfig;
     this.encoding = filterConfig.getInitParameter("encoding");
     String value = filterConfig.getInitParameter("ignore");
     if (value == null)
      this.ignore = true;
     else if (value.equalsIgnoreCase("true"))
      this.ignore = true;
     else if (value.equalsIgnoreCase("yes"))
      this.ignore = true;
     else
      this.ignore = false;


 }

 /* (non-Javadoc)
  * @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)
  */
 public void doFilter(ServletRequest request, ServletResponse response,
   FilterChain chain) throws IOException, ServletException {
  
  // TODO Auto-generated method stub
  if (ignore || (request.getCharacterEncoding() == null)) {
   String encoding = selectEncoding(request);
   if (encoding != null)
    request.setCharacterEncoding(encoding);
  }
  chain.doFilter(request, response);
 }

 /* (non-Javadoc)
  * @see javax.servlet.Filter#destroy()
  */
 public void destroy() {
  // TODO Auto-generated method stub
  
  this.encoding = null;
     this.filterConfig = null;


 }
 
  protected String selectEncoding(ServletRequest request) {

         return (this.encoding);

     }


}

在web.xml 文件中作如下设置:(我使用的是Struts框架)
<filter>
<filter-name>Encoding</filter-name>
<filter-class>com.lzy.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>Encoding</filter-name>
<servlet-name>action</servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name>Encoding</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>


最后,连接数据库时,使用下面的url:
jdbc:mysql://localhost:3306/数据库名?useUnicode=true&characterEncoding=GBK

Spring之Hello World

1.下载Spring相关的开发包
下载地址:http://sourceforge.net/project/showfiles.php?group_id=73357
有spring-framework-1.2.6-with-dependencies.zip,一個是spring-framework-1.2.6.zip,最好下载with-dependencies的,里面有另外一些附加包,下载后解压缩,dist目录下是spring自身的jar,lib目录下是附加的jar。
2.新建Java Project,将spring.jar(dist目录下)和commons-logging.jar(lib目录下)添加到project的build path中。
3.新建POJO Bean类:HelloBean
//HelloBean.java
/**
 *
 */
package com.lzy;

/**
 * @author lzy
 *
 */
public class HelloBean{
 
 private String hello;
 
 public void sayHello(){
  System.out.println(this.getHello());
 }

 /**
  * @return Returns the hello.
  */
 public String getHello() {
  return hello;
 }

 /**
  * @param hello The hello to set.
  */
 public void setHello(String hello) {
  this.hello = hello;
 }
 

}


4.新建文件bean.xml,将在这个XML文件中为一个HelloBean的实例的hello属性赋值。
//bean.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<description>Spring Quick Start</description>
<bean id="helloBean" class="com.lzy.HelloBean">
  <property name="hello">
   <value>hello world</value>
  </property>
</bean>
</beans>

5.新建测试类:TestSpring
//TestSpring.java
/**
 *
 */
package com.lzy;

import java.util.Locale;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

/**
 * @author lzy
 *
 */
public class TestSpring {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
  ApplicationContext ctx=new FileSystemXmlApplicationContext("bean.xml");
    HelloBean hello=(HelloBean)ctx.getBean("helloBean");
  hello.sayHello();
 }

}


6.运行测试类:
    如果没有出错,输出中将会看到“hello world”。

Eclipse下Hibernate入门


1.开发环境
     Eclipse 3.2+MySQL 4.0.16+Hibernate3.0
    首先应该安装好Eclipse和MySQL,此外准备好MySQL的JDBC Driver和Hibernate3.0,相关下载地址如下:
     Eclipse SDK:
        http://www.eclipse.org/downloads/index.php 
       MySQL及MySQL的JDBC Driver:
           http://www.mysql.org
       Hibernate:
          http://www.hibernate.org
       此外我还安装了Eclipse的一个Hibernate插件:
     Hibernate synchronizer
           http://hibernatesynch.sourceforge.net


       Plugin Search:
         http://eclipse-plugins.2y.net/eclipse/search.jsp 

       Hibernate synchronizer插件的安装和配置有问题请直接Google。

     在工程中其实只用到了Hibernate synchronizer插件的一部分功能,Hibernate依赖的相关jar包最好还是手动添加,因为最开始用Hibernate synchronizer添加时总是发生错误。
     将下载的Mysql driver和Hibernate包解压缩,我们需要的只是里面相关的jar,在Eclipse中新建Mysql_Driver和Hibernate两个user library,将mysql-connector-java-3.0.15-ga-bin.jar加入Mysql_Driver中,将hibernate3.jar,
,log4j-1.2.11.jar,antlr-2.7.5H3.jar,asm.jar,asm-attrs.jar,cglib-2.1.2.jar,commons-collections-2.1.1.jar,commons-logging-1.0.4.jar,dom4j-1.6.1.jar,ehcache-1.1.jar,jta.jar加入到Hibernate中。

2.开始
在Mysql中新建test数据库(Mysql其实有个空的test数据库),然后新建下面的Table

create table user (
 id int(10) not null auto_increment primary key,
 name varchar(20) not null,
 password varchar(20) not null,
 email varchar(50),
 address varchar(100)
)type=innodb;


新建Java Project,将Mysql_Driver,Hibernate两个user library添加到该工程的java build path中。

新建与数据表对应的POJO类:User和Contact

/**
 *
 * 
 */
package com.user;

/**
 * @author lzy
 *
 */
public class User{
    private Integer id;
    private String name;
    private String password;
    private Contact contact;
   

 /**
  * @return Returns the id.
  */
 public Integer getId() {
  return id;
 }
 /**
  * @param id The id to set.
  */
 public void setId(Integer id) {
  this.id = id;
 }
 /**
  * @return Returns the name.
  */
 public String getName() {
  return name;
 }
 /**
  * @param name The name to set.
  */
 public void setName(String name) {
  this.name = name;
 }
 /**
  * @return Returns the password.
  */
 public String getPassword() {
  return password;
 }
 /**
  * @param password The password to set.
  */
 public void setPassword(String password) {
  this.password = password;
 }
 /**
  * @return Returns the contact.
  */
 public Contact getContact() {
  return contact;
 }
 /**
  * @param contact The contact to set.
  */
 public void setContact(Contact contact) {
  this.contact = contact;
 }
   
   
}
/**
 *
 */
package com.user;

/**
 * @author lzy
 *
 */
public class Contact {
 private String email;
    private String address;

 /**
  * @return Returns the address.
  */
 public String getAddress() {
  return address;
 }
 /**
  * @param address The address to set.
  */
 public void setAddress(String address) {
  this.address = address;
 }
 /**
  * @return Returns the email.
  */
 public String getEmail() {
  return email;
 }
 /**
  * @param email The email to set.
  */
 public void setEmail(String email) {
  this.email = email;
 }
}

之后可以用synchronizer插件生成Hibernate配置文件和映射文件(相关过程可以参考http://www.ideagrace.com/html/doc/2005/08/01/00315.html),不过映射文件必须稍作修改。

hibernate.cfg.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration
    PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory >

  <!-- local connection properties -->
  <property name="hibernate.connection.url">jdbc:mysql://localhost/test</property>
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.username"></property>
  <property name="hibernate.connection.password"></property>
  <!-- property name="hibernate.connection.pool_size"></property -->

  <!-- dialect for MySQL -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <property name="hibernate.show_sql">True</property>
        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
     <mapping resource="User.hbm.xml"/>


    </session-factory>
</hibernate-configuration>

User.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
 "-//Hibernate/Hibernate Mapping DTD//EN"
 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping package="com.user">
 <class
  name="User"
  table="user"
 >
  <id
   name="Id"
   type="integer"
   column="id"
  >
   <generator class="native"/>
  </id>

  <property
   name="Name"
   column="name"
   type="string"
   not-null="true"
   length="20"
  />
  <property
   name="Password"
   column="password"
   type="string"
   not-null="true"
   length="20"
  />
  <component name="Contact" class="Contact">
   <property
   name="Email"
   column="email"
   type="string"
   not-null="false"
   length="50"
  />
  <property
   name="Address"
   column="address"
   type="string"
   not-null="false"
   length="100"
  />
  </component>
  


 </class> 
</hibernate-mapping>

 

3.测试
添加一个测试类:HibernateTest

package com.user;

import java.util.List;
import java.util.ListIterator;

import org.hibernate.*;
import org.hibernate.cfg.*;

public class HibernateTest {
    public static void main(String[] args) throws HibernateException {
        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
       
        //
        //testInsert(sessionFactory);
       
        //
        testQuery(sessionFactory);
       
         
        sessionFactory.close();
       
    }
    public static void testInsert( SessionFactory sessionFactory )throws HibernateException {
     
      Session session = sessionFactory.openSession();
        Transaction tx= session.beginTransaction();
        User user = new User();
        Contact contact=new Contact();
        contact.setEmail("email");
        contact.setAddress("address");
       
        user.setName("caterpillar");
        user.setPassword("password");
        user.setContact(contact);
       
        session.save(user);
        tx.commit();
        session.close();
        System.out.println("OK!");
   }
   
    public static void testQuery( SessionFactory sessionFactory )throws HibernateException {
     
     Session session = sessionFactory.openSession();
        Transaction tx= session.beginTransaction();
        User user = new User();
        Contact contact=new Contact();
                 
        Query query=session.createQuery("from User as user");
        //query.setCharacter(1, 'M');
        List names =query.list();
        for(ListIterator it=names.listIterator();it.hasNext();){
           user= (User)it.next();
           System.out.println("Id: " + user.getId());
            System.out.println("name: " + user.getName());
            System.out.println("password: " + user.getPassword());
            if(user.getContact()!=null){
             
             if(user.getContact().getEmail()!=null){
              System.out.println("Email: " + user.getContact().getEmail());
             }
             if(user.getContact().getAddress()!=null){
              System.out.println("Address: " + user.getContact().getAddress());
               
             }
            }
           
           
           
        }
         
      
        tx.commit();
        session.close();
     
    }
}

Eclipse下JSF入门

1.开发环境
   与Eclipse下Struts的开发类似,安装好Eclipse和Tomcat之后,还需要两个插件:tomcat 插件和JSF插件(如果相关插件还没有安装),以下是相关下载地址:
    Eclipse SDK:
        http://www.eclipse.org/downloads/index.php 
    JSF:
     https://sourceforge.jp/projects/amateras/files/  
      FaceIDE+htmlEditor,htmlEditer也是必要的
    Tomcat :
         http://www.sysdeo.com/eclipse/tomcatplugin 
    Plugin Search:
         http://eclipse-plugins.2y.net/eclipse/search.jsp 
   插件的安装和配置有问题请直接Google。
2.开始
    入门嘛,我们就找一个最简单的Login就可以了

    新建Tomcat project
    加入JSF支持

    新建一个ManagedBean:


/**
 *
 */
package com.jsf;




/**
 * @author lzy
 *
 */
public class UserBean {
private String name;
    private String password;
public String verify() {
     if(this.name.equals("name")&&this.password.equals("password"))
     
        return "failure";

   else
        return "success";
}

 
/**
* @return Returns the name.
*/
public String getName() {
return name;
}

/**
* @param name The name to set.
*/
public void setName(String name) {
this.name = name;
}


/**
* @return Returns the password.
*/
public String getPassword() {
return password;
}

/**
* @param password The password to set.
*/
public void setPassword(String password) {
this.password = password;
}


}

     新建两个JSP页面,login.jsp,welcom.jsp

login.jsp
<%@ page contentType="text/html; charset=GBK" %>

        </f:facet>
        </h:panelGrid>          
            <h:commandButton value="#{msgs.submitPromt}" action="#{user.verify}"/>
            <h:commandButton value="#{msgs.resetPromt}" type="reset"/>

3.测试
在test工程中选择tomcat project->Update context definition
然后运行Tomcat

Eclipse下Struts开发入门

 

1.开发环境
   开发之前首先应该准备好开发环境,Eclipse 3.X是一个不错的Java IDE,有很多插件可以供我们选择,服务器用Tomcat就行了。安装好Eclipse和Tomcat之后,还需要两个插件:tomcat 插件和Struts插件,以下是相关下载地址:
     Eclipse SDK:
        http://www.eclipse.org/downloads/index.php
    Struts:
     https://sourceforge.jp/projects/amateras/files/         StrutsIDE+htmlEditor,htmlEditer也是必要的
    Tomcat :
         http://www.sysdeo.com/eclipse/tomcatplugin
    Plugin Search:
         http://eclipse-plugins.2y.net/eclipse/search.jsp
   插件的安装和配置有问题请直接Google。
2.开始
    入门嘛,我们就找一个最简单的Login就可以了

    新建Tomcat project,如下图

    加入struts支持
    新建一个FormBean:LoginForm


/**
 *
 */
package com.test;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

/**
 * @author lzy
 *
 */
public class LoginForm extends ActionForm {

 private String name=null;
 private String password=null;
 /* (non-Javadoc)
  * @see org.apache.struts.action.ActionForm#reset(org.apache.struts.action.ActionMapping, javax.servlet.http.HttpServletRequest)
  */
 @Override
 public void reset(ActionMapping arg0, HttpServletRequest arg1) {
  // TODO Auto-generated method stub
  name=null;
  password=null;
 }
 /* (non-Javadoc)
  * @see org.apache.struts.action.ActionForm#validate(org.apache.struts.action.ActionMapping, javax.servlet.http.HttpServletRequest)
  */
 @Override
 public ActionErrors validate(ActionMapping arg0, HttpServletRequest arg1) {
  // TODO Auto-generated method stub
ActionErrors errors=new ActionErrors();
  
  if(name==null||name.length()<1){
   errors.add("username",new ActionMessage("errors.login.name.empty"));
   
  }
  if(password==null||password.length()<1){
   errors.add("password",new ActionMessage("errors.login.password.empty"));
   
  }
  
  return errors;
 }
 /**
  * @return Returns the name.
  */
 public String getName() {
  return name;
 }
 /**
  * @param name The name to set.
  */
 public void setName(String name) {
  this.name = name;
 }
 /**
  * @return Returns the password.
  */
 public String getPassword() {
  return password;
 }
 /**
  * @param password The password to set.
  */
 public void setPassword(String password) {
  this.password = password;
 }
}

 

 

     新建一个Action:LoginAction

/**
 *
 */
package com.test;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.struts.*;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
import org.apache.struts.action.ActionMessages;

/**
 * @author lzy
 *
 */
public class LoginAction extends Action {
 public ActionForward execute(ActionMapping mapping, ActionForm actionForm, HttpServletRequest request, HttpServletResponse response) throws Exception {
  // TODO Auto-generated method stub
  LoginForm loginForm=(LoginForm)actionForm;
  String name=loginForm.getName();
  String password=loginForm.getPassword();


 if(name.equals("name")&&password.equals("password")){
   HttpSession session=request.getSession(true);
   session.setAttribute("LOGGED_USER",name);

   
   return mapping.findForward("success");
   
  }
  else{
   ActionMessages errors=new ActionMessages();
   errors.add("login.failure",new ActionMessage("errors.login.failure")); 
   this.saveErrors(request,errors);
   
   return mapping.findForward("failure"); 
   
  }
  
 }

}

     新建两个JSP页面,login.jsp,index.jsp

login.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-tiles" prefix="tiles" %>

<html:html>
 <head>
  <html:base />
          </head>
 <body>
 <center>
 <html:errors />
  <html:form action="/login.do" method="POST">
  <table border="1">
   <tr>
    <td colspan="2"><bean:message key="login.jsp.form.title"/></td>
   </tr>
   <tr>
    <td align="right"><bean:message key="login.jsp.name"/></td>
    <td><html:text property="name" size="20"></html:text></td>
   </tr>
   <tr>
    <td align="right"><bean:message key="login.jsp.password"/></td>
    <td><html:password property="password" size="20"></html:password></td>
   </tr>
   <tr>
    <td colspan="2">
     <html:submit><bean:message key="form.submit"/></html:submit>
     <html:reset><bean:message key="form.reset"/></html:reset>
    </td>
   </tr>
 
  </table>
 
  </html:form>
  
 </center>
 </body>
</html:html>


index.jsp


<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-nested" prefix="nested" %>

<html:html>
 <head>
  <meta http-equiv="Content-Type" content="text/html; charset=GBK"/>
  <title></title>
 </head>
 <body>
 hello
  <logic:present name="LOGGED_USER">,<bean:write name="LOGGED_USER"/>
  </logic:present>
 </body>
</html:html>


     编辑WEB-INF/lib下的struts-config.xml

struts-config.xml

<?xml version="1.0"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>
  <data-sources>
  </data-sources>
  <form-beans>
    <form-bean name="loginForm" type="com.lzy.LoginForm"/>
  </form-beans>
  <global-exceptions>
  </global-exceptions>
  <global-forwards>
  </global-forwards>
  <action-mappings>
      <action path="/login" name="loginForm" type="com.lzy.LoginAction" scope="session" validate="true" input="/login.jsp">
      <forward name="failure" path="/login.jsp"/>
      <forward name="success" path="/index.jsp"/>
    </action>
  </action-mappings>
  <controller processorClass="org.apache.struts.tiles.TilesRequestProcessor"/>
  <message-resources parameter="MessageResources"/>

</struts-config>


       最后是资源文件

# -- standard errors --
errors.header=<UL><font color="red"><h2>Errors:</h2>
errors.prefix=<LI>
errors.suffix=</LI>
errors.footer=</font></UL><hr>


form.submit=Submit

form.reset=Reset


# -- login.jsp --
login.jsp.title=Login
login.jsp.form.title=Login
login.jsp.name=Name:
login.jsp.password=Password:

# -- login errors --
errors.login.name.empty=The name can not be empty!
errors.login.password.empty=The password can not be empty!
errors.login.failure=Login failed!<br> Please check your username and password!

 

3.测试
在test工程中选择tomcat project->Update context definition
然后运行Tomcat
http://127.0.0.1:8080/test/login.jsp
