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-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/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://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="http://www.mamicode.com/com.mysql.jdbc.Driver" />

				<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>

					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;

@Repository
public class UserDAO {
	
	@Resource
	private 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
@Service
public class UserService {

	@Resource
	private 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 {

	@Resource
	private 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;
	}
}
