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.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" >

</id>
<property

/>
<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();
}
}
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" %>
<%@ taglib uri="
http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="
http://java.sun.com/jsf/core" prefix="f" %>
<html>
<head>
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="
http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="
http://java.sun.com/jsf/core" prefix="f" %>
<html>
<head>
<link href="main.css" rel="stylesheet"/>
<title></title>
</head>
<body>
<f:view>
<f:loadBundle basename="com.jsf.MessageResources" var="msgs"></f:loadBundle>
<h:form>
<h:panelGrid columns="3" headerClass="header" rowClasses="evenRow,oddRow">
<f:facet name="header" >
<h:outputText value="#{msgs.header}"/>
</f:facet>
<h:outputText value="#{msgs.namePromt}"></h:outputText>
<h:inputText id="name" required="true" value="#{user.name}">
<f:validateLength minimum="2" maximum="10"></f:validateLength>
</h:inputText>
<h:message for="name" errorClass="errors"/>
<h:outputText value="#{msgs.passwordPromt}"></h:outputText>
<h:inputSecret id="password" value="#{user.password}" required="true" redisplay="true">
<f:validateLength minimum="2"></f:validateLength>
</h:inputSecret>
<h:message for="password"/>
<f:facet name="footer" >
<h:outputText value="#{msgs.footer}"/>
</f:facet>
</h:panelGrid>
<h:commandButton value="#{msgs.submitPromt}" action="#{user.verify}"/>
<h:commandButton value="#{msgs.resetPromt}" type="reset"/>
</h:form>
</f:view>
</body>
</html>
welcome.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="
http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="
http://java.sun.com/jsf/core" prefix="f" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK"/>
<title></title>
</head>
<body>
<f:view>
<h:outputText value="#{user.name}"/> is a good boy！
<h3>welcome JavaServer Faces</h3>
</f:view>
</body>
</html>
编辑WEB－INF/lib下的faces－config.xml
struts-config.xml
<?xml version="1.0"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "
http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config>
<navigation-rule>
<from-view-id>/login.jsp</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/welcome.jsp</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>failure</from-outcome>
<to-view-id>/login.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>com.jsf.UserBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
</faces-config>
最后是资源文件
# --login.jsp--
header=Welcom
namePromt=Name:
passwordPromt=Password:
amountPromt=Amount:
datePromt=Date:
submitPromt=Submit
resetPromt=Reset
footer=Thank you!
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/jsfTest/login.jsf
