hbn-annotations学习-不求人(ant junit环境配置)

学习就从官方的测试开始，但不知道怎么回事官方的测试有问题，这我就把我配置的简单junit环境共享给大家把！
1.下载 hibernate-annotations-3.4.0.GA 并解压 ,cd 到解压后目录下
2. $>ant junit （天知道，怎么官方出的东西测试不能通过！！）
   不要急，我们来看错误 (错误提示有删减)
     错误-1：$>build.xml:95: ./jdbc not found.
     解决办法-1： $>mkdir ./jdbc
3. $>ant junit
     错误-2：
      ./build.xml:124: The following error occurred while executing this line:
      ./build.xml:126: The following error occurred while executing this line:
      ./common-build.xml:349: .\src\filters\hsqldb.filter as it doesn't exist.
     解决办法-2：
       $>mkdir ./src/filters ;
       $>echo "" > ./src/filters/hsqldb.filter;
4. $>ant junit
     错误-3：
       ./build.xml:124: The following error occurred while executing this line:
       ./build.xml:126: The following error occurred while executing this line:
       ./common-build.xml:351: .\src\test-resources not found.
      $>mkdir ./src/test-resources ;
5. $>ant junit
     错误-4：没有ant 错误了！，但测试都为错误，那我们就看看第一个测试吧，找下原因！
         test-resources:
          [mkdir] Created dir: hibernate-anntations-3.4.0.GA\build\test-reports\hsqldb
          [echo] Running against db: hsqldb
          [junit] Running org.hibernate.test.annotations.ConfigurationTest
          [junit] Tests run: 7, Failures: 0, Errors: 6, Time elapsed: 1.218 sec
          .............
     $>find . -name "ConfigurationTest.java" #pwd /hibernate-anntations-3.4.0.GA
        ./test/org/hibernate/test/annotations/configuration/ConfigurationTest.java
        ./test/org/hibernate/test/annotations/ConfigurationTest.java
      根据路径 org.hibernate.test.annotations.ConfigurationTest
      gvim ./test/org/hibernate/test/annotations/ConfigurationTest.java
      发现第20行: cfg.configure( "org/hibernate/test/annotations/hibernate.cfg.xml" );
      感觉应该没有配置 jdbc
      gvim ./test/org/hibernate/test/annotations/hibernate.cfg.xml #果然没配置
      我这就放个我的简单配置上来(使用 hbm hsqldb 内存数据库测试 )：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
        <property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="connection.url">jdbc:hsqldb:mem:hbn_ann</property>
        <property name="connection.username">sa</property>
        <property name="connection.password"></property>

        <mapping resource="org/hibernate/test/annotations/Boat.hbm.xml"/>
        <mapping package="org.hibernate.test.annotations"/>
        <mapping class="org.hibernate.test.annotations.Plane"/>
  </session-factory>
</hibernate-configuration>

      我这就是要hsqldb吧，既然上面错误1有 jdbc 文件夹，那就是放 jdbc jar 的地方
      $> cp ../hsqldb.jar ./jdbc

6. $>ant junit
     呵呵测试第一个正确了！（目前配置后，测试环境并不是全部都正确，比如第2个测试）
     其他测试错误日志在    .\build\test-reports\hsqldb ...
     比如第2个错误异常部分
      org.hibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect.
    at org.hibernate.dialect.Dialect.instantiateDialect(Dialect.java:256)
    at org.hibernate.dialect.Dialect.getDialect(Dialect.java:234)
        ........ 大家一边学习，一边配置测试环境吧。
    错误日记都会在 build\test-reports\hsqldb下

javascript 基础总结（面向对象）

javascript 学习

javascript 大体上可分为3个不同部分组成：核心（ECMAscript）,文本对象(DOM),浏览器对象(BOM)

核心（ECMAscript）：关键字，语句，运算符，对象
文本对象(DOM)：DOM将把整个页面规划成由节点层级构成的文档.

解析遵循 W3C html dom 标准：
W3C dom 参考特别关注 DOM Node 说明

BOM 浏览器对象. cookie,弹出新浏览器，浏览器设置大小

核心（ECMAscript）Global 内置对象；
方法： parseInt(),isNan(),encodeURI()...等都为此对象方法
特别注意 eval();动态语言的象征比如：eval("alert('hi')"); 但这个方法很邪恶（安全方面）
文本对象(DOM)说明：

<bookstore>
 <book category="cooking">
 <title lang="en">Everyday Italian</title> 
 <author>Giada De Laurentiis</author> 
 <year>2005</year> 
 <price>30.00</price> 
 </book>
</bookstore>

DOM node tree

Node tree

1. ECMAscript基础

$ 变量弱类型 ; 匈牙利类型标示 : var iOuouValue=100;

$ 结束行分号有无都可以; 但再 onsubmit="javascript:function();return false;"

$ 关键字 ; 提别注意

"constructor" bean.constructor

//print bean function(){

....

}

"typeof" var test=1; alert(typeof testX); //output "undefined"

"NaN" - not a number -> isNan("blue"); //output "true" ->isNan("123"); //output "false"

$ 对象; var o = new Object(); var a = {}

这里特别说明下我们普通写的一个 function 就是一个 object

这 var a = {name:"刘凯毅"} 等同与 var a = function(){this.name="刘凯毅"};

来个 {name:"test",pass:"123456",addr:"bj"} //这是什么？！ json

当 var str = '{name:"test",pass:"123456",addr:"bj"}'

var objectBean = eval(str); //这里就是对象 objectBea.name 使用了

域概念：

<SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
sColor = 'red';
sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello World!
alert(sColor); //red
</SCRIPT>

<SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
var sColor = 'red';
sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello World!
alert(sColor); // 什么都没有
</SCRIPT>

<SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
var sColor = 'red';
var sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello
alert(sColor); // 什么都没有
</SCRIPT>

为面向对象做基础：object prototype 类型的对象应用。参考

// 最简单的继承
Object.prototype.inObj = 1;

function A()
{
    this.inA = 2;
}

A.prototype.inAProto = 3;

B.prototype = new A;            // Hook up A into B's prototype chain
B.prototype.constructor = B;
function B()
{
    this.inB = 4;
}

B.prototype.inBProto = 5;

x = new B;
document.write(x.inObj + ', ' + x.inA + ', ' + x.inAProto + ', ' + x.inB + ', ' + x.inBProto);

//1, 2, 3, 4, 5
//增加点信心 http://www.json.org/json.js

Object.prototype.toJSONString = function (filter) {
 return JSON.stringify(this, filter);
};
后我们就可以使用 bean.toJSONString()不是吗？

$ arguments ;

function getFun(){alert(arguments.length);} ;

getFun("xx") //output 1

getFun("xx",23) //output 2

$ 语句 ;特殊说明下 for

for(var i=0i<iCount;i++) 或 for( attr in object ) ;

如果无聊你可以 for( sProp in window ){alert(sProp+"你丫点啊！");} //看看 javascript 的反射

面向对象：

var bean = new Bean();

1.工厂方法

function getAttr(){

alert(this.attr)

}

function Bean(tattr){

var bean = new Object;

bean.attr = tattr;

bean.getAttr = getAttr;

return bean ;

}

根本就是山寨版面向对象

2.构造

function Bean(tattr){

this.attr = tattr ;

bean.getAttr = function(){

alert(this.attr);

}

其上 2 总再Bean 对象创建时，方法会 “重复生成函数”！

3.原型模式

function Bean(){}

Bean.prototype.attr = "";

Bean.prototype.getAttr=function(){alert(this.attr);}

解决 “重复生成函数” 问题，但新的问题 Bean.prototype.getArray = new Array();

其 new 对象 bean1 和 bean2 都会共享 new Array 空间(是我们不想看到的)

4.混合模型 :) 哈哈

function Bean(){

this.attr= "";

this.getArray=new Array;

}

Bean.prototype.getAttr=function(){alert(this.attr);}

5.动态原型（注意下面开始，就是真正的面向对象！！！）

function Bean(){

this.attr= "";
this.getArray=new Array;

//classload 加载时

if(typeof Bean._initialized == "undefined" ){

Bean.prototype.getAttr=function(){alert(this.attr);};

Bean._initialized= true ;

}

/****************************************************************/

对象继承

1.对象冒充！！(可支持多继承，山寨很强大)

function classA(sstr){

this.color = sstr ;

this.sayColor = function(){

alert(this.color);

};

}

function classC(){}

function classB(){

this.newMethod =ClassA ;

this.newMethod();

delete this.newMethod ;

this.newMethod =ClassC ;

this.newMethod();

delete this.newMethod ;

this.arrt = "google";

}

2.call() apply() 也山寨,

function classA(sstr){

this.color = sstr ;

this.sayColor = function(str){

alert(str+this.color);

};

}

function classB(){

// this.newMethod =ClassA ;

// this.newMethod();

// delete this.newMethod ;

classA.call(this,"red");

//classA.apply(this,new Array("red"))

this.arrt = "baidu";

}

3.正统的继承 原型链 (但不支持多继承)
    function classA(){this.oo="test";}
    classA.prototype.color = "red";
    function classB(){}
    classB.prototype = new classA ;
    classB.prototype.sayName = function(){
        alert( this.color );
   }
   var bb = new classB ;
   bb.sayName(); // output red
   alert(bb.oo); // output test

   alert( bb instanceof classA); //output true
   alert( bb instanceof classB); //output true
4.如果你要多继承！！并且还支持 instanceof
        混合方式：
        function classA(){}
        function classB(){}
        function classC(){
            classA.call(this);
            classC.call(this);
       }
        classC.prototype = new classA ;//注意这 instanceof 只能对 A有用

tomcat 调试

tomcat > server.xml

      <Host name="localhost" appBase="webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">

<Context docBase="D:/workspace/meganotes/mn_mod_admin/target/mn_mod_admin/" path="/" />

。。。。

关键：在Context上不要加reloadable和debug属性
然后使用eclipse tomcat 调试
ok

jquery 补全使用笔记

官方上下
http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/

$.补全中文修改
    jquery.autocomplete.js 中
    $input.bind(($.browser.opera ? "keypress" : "keydown")
    改为
    $input.bind(($.browser.opera ? "keypress" : "keyup")

$. 在 localdata.js 》》 var cities = [..
   中放些中文测试吧

测试页面，最简单的使用页面。（应该算是最简单补全测试了）

使用json

ajax Form

不要为拼写 ajax url 而郁闷了。希望能对大家有帮助。

/*
    1.form ajax 使用：
    eG: form就是普通的 html form
        <input type="button" value="xx" onclick="formAjax('data.jsp',this.form,ajaxReturn)"/>
        function ajaxReturn(data){
            document.getElementById("div1").innerHTML =  data ;
        }


    2.ajax 使用   ：
    AjaxFunction
        AjaxFunction('url?param=tt&param2=te',function(text){
            alert(text);
        });

    3.迭代器：
    recursiveNodes(array,dom,pushFun,layer)
   array 迭代寄存器
   dom 被迭代对象
       pushFun 自定义收集方法
            pushFun(array,node,layer)
               node 迭代中对象
       layer 深度
    EG:
    var arr = [] ;
    recursiveNodes(arr ,dom,function(array,node,layer){
            arr.push(node);
     },2);


*/
var _request;
try {
    this._request = new XMLHttpRequest();

        } catch (e) {
            request = false;
        }

google proto buffer 使用（java）

主页：http://code.google.com/apis/protocolbuffers/docs/overview.html

testProto.proto

package foo.bar;
option java_package = "com.proto";

message Person {
  required string name = 1;
  required int32 id = 2;
  optional string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
  }

  message PhoneNumber {
    required string number = 1;
    optional PhoneType type = 2 [default = HOME];
  }

  repeated PhoneNumber phone = 4;
}

运行命令
'/home/kaiyi/proto/bin/protoc' --java_out=src testProto.proto

使用( 本类可用，builder 可改，开用但 list 删除要使用比较郁闷的方法删除！)

package unit;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;

import com.google.protobuf.InvalidProtocolBufferException;
import com.proto.TestProto;
import com.proto.TestProto.Person;
import com.proto.TestProto.Person.PhoneNumber;

public class Main {
    public static void main(String[] args) throws InvalidProtocolBufferException {
        //空创建
        Person.Builder builder = Person.newBuilder();
        builder.setName("liukaiyi");
        builder.setId(1);

        builder.setEmail("email");

        PhoneNumber.Builder pBuilder1 = PhoneNumber.newBuilder();
        pBuilder1.setNumber("1");
        pBuilder1.setType(TestProto.Person.PhoneType.MOBILE);


        PhoneNumber.Builder pBuilder2 = PhoneNumber.newBuilder();
        pBuilder2.setNumber("2");
        pBuilder2.setType(TestProto.Person.PhoneType.HOME);



        builder.addPhone(pBuilder1);
        builder.addPhone(pBuilder2);

//此处为存储到数据库或传输！
byte[] data = builder.build().toByteArray() ;
        for(byte tb : data )
            System.out.print( (char)tb );


        //组建
        Person person = Person.parseFrom(data);
        Person.Builder builder2 = Person.newBuilder(person);
        builder2.setEmail("test");

        PhoneNumber.Builder pBuilder3 = PhoneNumber.newBuilder();
        pBuilder3.setNumber("3");
        pBuilder3.setType(TestProto.Person.PhoneType.HOME);
        builder2.addPhone(pBuilder3);

//这我最不明白的地方， list 这只能使用这种方法才可以删除 list ????
        List list = new ArrayList(builder2.getPhoneList());
        List<PhoneNumber> ltmp = builder2.getPhoneList() ;
        for(int i=0;i<list.size();i++ ){
            if(ltmp.get(i).getNumber().equals("2"))
                list.remove( ltmp.get(i) ) ;
        }
        builder2.clearPhone().addAllPhone(list);
        builder2.clearEmail();

        System.out.println(list.size());
        System.out.println();
        byte[] data2 = builder2.build().toByteArray() ;
        for(byte tb : data2 )
            System.out.print( (char)tb );

部分高级查询 sql 拼写笔记（mysql）

参考：http://www.programbbs.com/bbs/view25-12320-1.htm
但上面的一些sql语句，有查询时间问题，在此我已于改正了并希望和大家分享。

---------自我感觉第四题很不错！-------------

----------------------------------------------------------------------
第一题(只要重复的都要输出)
----------------------------------------------------------------------

create table c (id int );
insert into c values (1),(2),(3),(4),(3),(5),(6),(1);
结果:
select id from c group by id having count(id)>1 ;

附加（查询重复最多的倒排）

select bid,count(bid) as cu from tb group by bid having count(bid)>1 order by cu desc

----------------------------------------------------------------------
第二题(报表查询横向输出)
查询后的结果：
Create table d(id int,name varchar(50));
insert into d values(1,'gly');
insert into d values(2,'ptgly');
insert into d values(3,'ybgly');
insert into d values(4,'ptgly');
insert into d values(5,'ybgly');
+---+-----+------+
|gly|ptgly|ybgly |
|---+-----+------+-
|1 |2 |2 |
+---+-----+------+
-----------------------------------------------------------------------

select
    sum(case when name='gly' then 1 else 0 end ) as gly  ,
    sum(case when name='ptgly' then 1 else 0 end ) as ptgly  ,
    sum(case when name='ybgly' then 1 else 0 end ) as ybgly
from d ;

第三题
可以根据上面 2,4 可以得出。
下面我们详细说下 4题。

-----------------------------------------------------------------------
第四题（复杂组合查询！）
create table table_a (No int, No2 int,num double,itime date);
insert into table_a values
     (1234,567890,33.5,'2004-12-21'),
     (1234,598701,44.8,'2004-11-21'),
     (1234,598701,45.2,'2004-10-01'),
     (1234,567890,66.5,'2004-9-21'),
     (3456,789065,22.5,'2004-10-01'),
     (3456,789065,77.5,'2004-10-27'),
     (3456,678901,48.5,'2004-12-21');
按月统计销售表中货物的销售量数
查询结果如下：
No， No2 ，   九月，　十月，十一月，十二月
1234，567890， 66.5 ，　 0 ，　0 ， 33.5
1234，598701， 0   ，　45.2，　44.8，　0
3456，789065，　0 ，　 100，　0 ，　 0
3456，678901，　0　，    0，    0 ， 48.5

//当然也可以使用mysql 时间函数在软件编辑时你可以输入 String[] 并根据数据动态拼写 sql( case部分！！ )
//这个例子很好哦！报表可以一句sql 得出！
select NO,NO2,
    sum(case  when itime like '2004-%9%' then num else 0 end) as 9M,
    sum(case  when itime like '2004-10%' then num else 0 end) as 10M,
    sum(case  when itime like '2004-11%' then num else 0 end) as 11M,
    sum(case  when itime like '2004-12%' then num else 0 end) as 12M
from table_a group by no,no2 order by no,no2 ;

第五题
代码,名称
1     a
2     b
11    c
(代码11表示为1的下级)
我要通过一条句子,得出如下结果:

代码,名称,有无下级
1     a     有
2     b     无
11    c     无

Create table TabTest(t_Code varchar(10),t_Name varchar(10));
insert into TabTest values('1','a');
insert into TabTest values('2','b');
insert into TabTest values('11','c');
--------------------------------------------------------------

select tt1.t_Code,tt1.t_name,(
     case
             when exists (select 1 from tabtest tt2
                                        where tt2.t_code like CONCAT(tt1.t_code,'%') and
                                        tt2.t_code <> tt1.t_code )  then 'you'
             else 'wu'
      end ) as you_wu
from tabtest  tt1 ;
