Hibernate Spring Struts JSP XML

趁着测试空闲，学习struts2.0+spring2.0+hibernate3.2的整合，对这3种技术都只有最基本的了解，网上查了N多资料，找到一篇介绍整合的文章，不过用的是hibernate3.1。
资料链接如下：hibernate3.1http://blog.sina.com.cn/s/blog_4c5ce20701000b7m.html
1. 新建web工程：
[img]http://shiningwu.iteye.com/upload/picture/pic/12421/2c42b467-8f44-3220-aed1-6b642db43162.bmp [/img]
点击“finish”。
2. 加入spring2组件
[img]http://shiningwu.iteye.com/upload/picture/pic/12437/7123801b-f9f2-3249-a9e9-ce09ee652037.bmp [/img]
选择Spring 2.0 Core Lobraries、Spring 2.0 Testing Support Libraries、Spring 2.0 Web Libraries、Hibernate 3.2 Core Libraries、Hibernate 3.2 Annotations & Entity Manager、Hibernate 3.2 Advanced Support Libraries包。
选择Copy checked Library contents to project folder(TLDs always copied)，点击“next”；[img]http://shiningwu.iteye.com/upload/picture/pic/12435/43107a35-b0e5-31d1-8134-bd4e9674bc32.bmp [/img]
点击“finish”。
3. 手工加入需要的jar文件。
需要手工添加一些jar文件到WEB-INF/lib里面，不加这些文件，加入hibernate组件后会报错。
commons-dbcp.jar
spring-hibernate.jar
spring-dao.jar
spring-jdbc.jar
commons-pool.jar
commons-collections.jar
struts2-spring-plugin-2.0.11.1.jar
spring-orm.jar
同时删除commons-collections2.11.jar
4. 加入hibernate组件。
[img]http://shiningwu.iteye.com/upload/picture/pic/12433/d8e96d08-07d5-3f18-b0cd-14dbe2fcac2b.bmp [/img]
由于eclipse6.0不支持hibernate3.2，刚刚在添加spring2.0组件时已加入hibernate3.2的jar文件，在这里就不添加hibernate3.1的jar文件。选择Copy checked Library contents to project folder(TLDs always copied)，点击“next”；
[img]http://shiningwu.iteye.com/upload/picture/pic/12431/55d58d8f-bde5-354e-99e3-f10711230e5e.bmp [/img]

选择Srping configuration file(applicationContext.xml)，使用spring管理hibernate，点击“next”；
[img]http://shiningwu.iteye.com/upload/picture/pic/12429/1083558e-001e-3076-aede-f29f5103500c.bmp [/img]

选择Existing Spring configuration file，填写SessionFactory ID，点击“next”；
[img]http://shiningwu.iteye.com/upload/picture/pic/12447/f1bd99c7-6f3b-33e0-97b0-6d11972381ae.bmp [/img]
填写DataSource名称，选择DB Driver，点击“next”；
[img]http://shiningwu.iteye.com/upload/picture/pic/12445/b343f79f-078d-3afc-a8e0-31e4ff07a40a.bmp [/img]
取消Create SessionFactory class选项，点击“finish”；
applicationContext.xml生成如下代码：

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">


	<bean id="DataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName"
			value="com.mysql.jdbc.Driver">
		</property>
		<property name="url"
			value="jdbc:mysql://192.168.151.238:3306/chgl">
		</property>
		<property name="username" value="vcom"></property>
		<property name="password" value="vcom_8968888"></property>
	</bean>
	<bean id="SessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="DataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
			</props>
		</property>
	</bean>
	</beans>

5. 加入struts2.0组件
加入struts2.0的jar文件
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.8.jar
xwork-2.0.3.jar
6. 修改web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name>test</display-name>
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
 </context-param>
 <filter>
 <filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
 <init-param>
 <param-name>encoding</param-name>
 <param-value>UTF-8</param-value>
 </init-param>
 </filter>
 <filter>
 <filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>struts2</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
    <welcome-file-list>
       <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
     <listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
 </listener>
</web-app>

7. 建立映射
选择Window-Open perspective-MyEclipse Hibernate,选择使用的DB Driver，右键点击，选择“open connection…”
[img]http://shiningwu.iteye.com/upload/picture/pic/12443/06f3b3b8-617a-37f0-bc79-b1dc67da2e22.bmp [/img]
选择要使用的表，右键点击，选择“Hibernate Reverse Engineering”；
[img]http://shiningwu.iteye.com/upload/picture/pic/12441/be787f3e-3a4e-36e8-977f-e6b40da97d04.bmp [/img]
点击“next“
[img]http://shiningwu.iteye.com/upload/picture/pic/12439/9f34bedb-db53-3b49-95fc-971260a81ac4.bmp [/img]
也可填写“sequence “ or ”assigned“，点击“next“
[img]http://shiningwu.iteye.com/upload/picture/pic/12453/97b3852c-a42d-34fc-9277-11e912cf96a2.bmp [/img]
点击“finish“。
到这里，完成了struts2.0+spring2.0+hibernate3.2的基本配置。
8. 编写action及struts.xml

package com.vcom.login;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.hibernate.Session;
import org.hibernate.criterion.Restrictions;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.opensymphony.xwork2.ActionSupport;
import com.vcom.hibernate.XtYhxx;
import com.vcom.hibernate.XtYhxxDAO;

public class Login extends ActionSupport{
	    private XtYhxxDAO xtyhxxDAO;
	    private String username;
	    private int rowid;
	    private String password;
	    private String message;
	    private ApplicationContext context;
	    public String getMessage() {
			return message;
		}
		public void setMessage(String message) {
			this.message = message;
		}
		public String getUsername() {
	       return username;
	    }
	    public void setUsername(String username) {
	       this.username = username;
	    }
	    public String getPassword() {
	       return password;
	    }
	    public void setPassword(String password) {
	       this.password = password;
	    }
	    
		public XtYhxxDAO getXtyhxxDAO() {
			return xtyhxxDAO;
		}
		public void setXtyhxxDAO(XtYhxxDAO xtyhxxDAO) {
			this.xtyhxxDAO = xtyhxxDAO;
		}

		public int getRowid() {
			return rowid;
		}
		public void setRowid(int rowid) {
			this.rowid = rowid;
		}
		public ApplicationContext getContext() {
			return context;
		}
		public void setContext(ApplicationContext context) {
			this.context = context;
		}
		
	    public String execute() {
	    	XtYhxx  xtyhxx = new XtYhxx();
	    	//XtYhxxDAO xtyxxdao=new XtYhxxDAO();
	    	//context=new ClassPathXmlApplicationContext("applicationContext.xml");
	    	//XtYhxxDAO xtyxxdao=(XtYhxxDAO)context.getBean("XtYhxxDAO");
	    	xtyhxx.setYhdm(username);
	    	//xtyhxx.setYhmm(password);
	    	xtyhxx.setRowid(rowid);
	    	message ="Welcome, "+ xtyhxx.getRowid()+","+xtyhxx.getYhdm();
	    	Session session=xtyhxxDAO.getHibernateTemplate().getSessionFactory().openSession(); 
	        try{
	        	//xtyhxxDAO.save(xtyhxx);
	        	//xtyhxxDAO.delete(xtyhxx);
	        	//XtYhxx aa=xtyhxxDAO.findById(rowid);
	        	//System.out.println("------"+aa.getYhdm());
	        	//Example example = Example.create(xtyhxx);
	        	//List list=xtyxxdao.findByExample(xtyhxx);     	
	        	//Criteria criteria = session.createCriteria(XtYhxx.class).add(example);
	        	//List list = criteria.list();  
	        	Map map = new HashMap();
				map.put("yhdm", username);
				map.put("yhmm", password);
				map.put("rowid", rowid);
	        	List list=session.createCriteria(XtYhxx.class).add(Restrictions.allEq(map)).list();
	        	//System.out.println("------"+list.size());
	        	if(list.size()==0)  message ="Invalid user or password";
	        }catch (Exception ex){
	            ex.printStackTrace();
	            return ActionSupport.INPUT;
	        }finally {
	            if (session.isOpen()) {
	            	session.close();
                 }
	        }
	       return SUCCESS;
	    }

	} 
struts.xml
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <!-- <constant name="struts.objectFactory" value="spring" /> 是在后面的spring2配置中用到意思是把控制交给spring2  -->
    <constant name="struts.objectFactory" value="spring" />
    <include file="struts-default.xml"></include>
    <package name="com.vcom.login" extends="struts-default">
    <!-- <action name="Login" class="Login"> 这里用class来关联spring2配置文件中的配置关联  -->
        <action name="Login" class="LoginAction">
            <result>/login/login.jsp</result>
            <result name="INPUT">/login/login.jsp</result>
        </action>
     </package>
</struts>

9. 修改applicationContext.xml
加入

<bean id="LoginAction" class="com.vcom.login.Login" >
       <property name="xtyhxxDAO">
           <ref bean="XtYhxxDAO" />
       </property>  
</bean>

10. 编写login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>   
    <title>My JSP 'index.jsp' starting page</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>
  
  <body>
    <table width="300" border="0">
        <s:form action="Login" theme="simple">
        <tr>
        <td width=50%>用户名:</td>
        <td width=50%><s:textfield name="username" /></td>
        </tr>
       <tr>
        <td width=50%>密码:</td>
        <td width=50%><s:textfield name="password" /></td>
        </tr>
        <tr><td colspan=2 align=center width=100%><s:submit /></td></tr>
        <tr>
        <td colspan=2 align=center width=100%><s:property value ="message"/></td>
        </tr>
        </s:form>
        </table>
  </body>
</html>

11. 新建DB Driver
选择Window-Open perspective-MyEclipse Hibernate,在左边DB Browser中点击右键-new
[img]http://shiningwu.iteye.com/upload/picture/pic/12451/64572ad8-e483-3ab0-86be-8d8f31a21dc0.bmp [/img]
点击“next“；
[img]http://shiningwu.iteye.com/upload/picture/pic/12449/4cd6e96d-7960-322e-a7a0-edee730ab986.bmp [/img]
点击“finish“。

12. 需要注意的事项
1. WEB-INF中

 <context-param>
        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
 </context-param>

applicationContext.xml的路径必须和实际一致，applicationContext.xml建议放在classes下，这样在实际引用时不用写绝对路径。
2. struts.xml中

<action name="Login" class="LoginAction">
            <result>/login/login.jsp</result>
            <result name="INPUT">/login/login.jsp</result>
        </action>

Action中成功返回success，在struts.xml中不能写成<result name=”success”>/login/login.jsp</result>，会报找不到result success的异常。
