Struts2.1.6 + Spring2.5+Hibernate3.2整合
http://www.cnblogs.com/kay/archive/2009/07/07/1518278.html首先来看需要的jar包：
在web.xml中的配置：
<?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"><!-- Struts2 --><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- OpenSession In View --><filter><filter-name>openSessionInView</filter-name><filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class></filter><filter-mapping><filter-name>openSessionInView</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- Spring配置 指定spring配置文件位置--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:ApplicationContext.xml</param-value></context-param><!-- 实例化Spring容器 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>
在Struts2的配置文件struts.xml中的配置：
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN""http://struts.apache.org/dtds/struts-2.1.dtd"><struts><package name="myStruts" extends="struts-default" namespace="/"><!-- 使用通配符 --><action name="*_*" class="{1}" method="{2}"> <result name="list">/{1}/list.jsp</result><result name="input">/{1}/update.jsp</result><result name="reload" type="chain">{1}_list</result></action></package></struts>需要注意的是class的名字要和Spring中管理Action的Bean的名字相同。
由于需要将Struts2的Action交给Spring去管理，我们在struts.properties配置文件中加入：
struts.objectFactory=spring
再来看看Spring的配置文件ApplicationContext.xml的配置：
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"><!-- 启用自动扫描 --><context:component-scan base-package="com.javaonroad"></context:component-scan><!-- 事务管理 --><tx:annotation-driven transaction-manager="transactionManager" /><bean id="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean><bean id="dataSource"class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="com.mysql.jdbc.Driver" /><property name="jdbcUrl" value="jdbc:mysql:///struts2" /><property name="maxIdleTime" value="25000" /><property name="properties"><props><prop key="user">root</prop><prop key="password">root</prop><prop key="c3p0.acquire_increment">2</prop><prop key="c3p0.max_size">20</prop><prop key="c3p0.min_size">1</prop></props></property></bean><!-- 定义Hibernate SessionFactory --><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><!-- dataSource可以为任意的数据源 例如DBCP、C3P0 --><property name="dataSource" ref="dataSource"></property><!-- 映射文件路径 --><property name="mappingResources"><value>com/javaonroad/pojo/User.hbm.xml</value></property><!-- 其他的Hibernate常用配置 --><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop></props></property></bean></beans>
由于启用了自动扫描，所以在dao、service以及action中都要使用注解进行标记：
DAO类：
package com.javaonroad.dao;import java.util.List;import javax.annotation.Resource;import org.hibernate.Criteria;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.stereotype.Repository;import com.javaonroad.pojo.User;@Repositorypublic class UserDAO {@Resourceprivate SessionFactory sessionFactory;private Session getSession(){return sessionFactory.getCurrentSession();}public void save(User user){getSession().save(user);}public void update(User user){getSession().update(user);}public User get(int id){return (User) getSession().get(User.class, id);}public User findUserByNameAndPwd(User user){String hql = "from User where name = :name and pwd = :pwd";Query query = getSession().createQuery(hql);query.setString("name", user.getName());query.setString("pwd", user.getPwd());return (User) query.uniqueResult();}public void delete(int id){getSession().delete(get(id));}@SuppressWarnings("unchecked")public List<User> findAll(){Criteria cri = getSession().createCriteria(User.class);List<User> list = cri.list();return list;}}Service类：
其中事务同样采用注解：
package com.javaonroad.service;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import com.javaonroad.dao.UserDAO;import com.javaonroad.pojo.User;@Transactional@Servicepublic class UserService {@Resourceprivate UserDAO userDAO;public User login(User user){return userDAO.findUserByNameAndPwd(user);}public void save(User user){userDAO.save(user);}public void update(User user){userDAO.update(user);}public User get(String id){return userDAO.get(Integer.valueOf(id));}public void delete(String id){userDAO.delete(Integer.valueOf(id));}public List<User> findAll(){return userDAO.findAll();}}最后是我们的Action类，由于Struts2的Action的线程安全的所以在注解的时候需要改变Spring默认的Scope属性：
package com.javaonroad.web;import java.util.List;import javax.annotation.Resource;import javax.servlet.http.HttpSession;import org.apache.struts2.ServletActionContext;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import com.javaonroad.pojo.User;import com.javaonroad.service.UserService;import com.opensymphony.xwork2.ActionSupport;@Controller("user")@Scope("prototype")public class UserAction extends ActionSupport {@Resourceprivate UserService userService;private User user;private String id;private List<User> list;/** * */private static final long serialVersionUID = 5638432269244791021L;/*业务方法*/public String login()throws Exception{User currUser = userService.login(user);if(currUser != null){HttpSession session = ServletActionContext.getRequest().getSession();session.setAttribute("currUser", currUser);return list();}else{return "input";}}public String list()throws Exception{list = userService.findAll();return "list";}public String add()throws Exception{userService.save(user);return "reload";//list();}public String delete()throws Exception{userService.delete(id);return "reload";}public String update()throws Exception{userService.update(user);return "reload";}public String toUpdate()throws Exception{user = userService.get(id);return "input";}/*geterAndSeter*/public User getUser() {return user;}public void setUser(User user) {this.user = user;}public List<User> getList() {return list;}public void setList(List<User> list) {this.list = list;}public String getId() {return id;}public void setId(String id) {this.id = id;}}列表页面list.jsp:
