前提是struts2 和hibernate 已经已成。

第一步要引入spring 需要的jar包，我这里使用的sping2.0 ，在dist文件夹下引入spring.jar 和 \lib\c3p0下的

c3p0-0.9.0.4.jar。

第二步、改变Dao层数据库访问方法，采用spring的方法，看一下DaoUserLogin.java

package com.hrbkejia.dao.impl;

import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import org.springframework.orm.hibernate3.HibernateCallback;
import com.hrbkejia.bean.UserManager;
import com.hrbkejia.dao.UserManagerDao;
import com.hrbkejia.util.HibernateSessionFactory;

 

public class UserManagerDaoImpl extends HibernateDaoSupport implements UserManagerDao{
 

 /**
  * 按照用户名和密码查询登录用户实例
  */
 public UserManager queryUserManager(final UserManager userManager) throws Exception {
  
  List list = this.getHibernateTemplate().find(
    "from com.hrbkejia.bean.UserManager as user where user.userName=? and user.passWord=?",
    new String[]{userManager.getUserName(),userManager.getPassWord()});
  if(list != null && list.size() >= 1){
   return (UserManager)list.get(0);
  }
  return null;
   
 }
 
 public static void main(String [] args){
  UserManagerDaoImpl s = new UserManagerDaoImpl();
  UserManager userManager = new UserManager();
  userManager.setUserName("admin");
  userManager.setPassWord("admin");
  try {
   //s.saveUserManager(userManager);
   UserManager u = (UserManager)s.queryUserManager(userManager);
   System.out.println(u.getUserName());
   
  
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 }

 public boolean saveUserManager(final UserManager userManager) throws Exception {

  try{
   this.getHibernateTemplate().save(userManager);
  }catch(Exception e){
   if(e != null){
    e.printStackTrace();
    return false;
   }
  }
  return true;
 }


 public List queryAllUserManager() throws Exception {
  return (List<UserManager>)this.getHibernateTemplate().find(
    "from com.hrbkejia.bean.UserManager as user ");
  
 }
 public List<UserManager> queryAllUserManager(final int startNum, final int endNum) throws Exception {
  return (List<UserManager>)getHibernateTemplate().executeFind(new HibernateCallback() { 
   public Object doInHibernate(Session session) 
   throws HibernateException, SQLException { 
   Query query = session.createQuery("from com.hrbkejia.bean.UserManager"); 
   query.setFirstResult(startNum); 
   query.setMaxResults(endNum); 
   List list = query.list(); 
   return list; 
   } 
   }); 
 }

 public boolean deleteUserManager(UserManager userManager) throws Exception {
  
  try{
   this.getHibernateTemplate().delete(userManager);
  }catch(Exception e){
   if(e != null){
    e.printStackTrace();
    return false;
   }
  }
  return true;
 }

 public boolean updateUserManager(UserManager userManager) throws Exception {
  try{
   this.getHibernateTemplate().update(userManager);
  }catch(Exception e){
   if(e != null){
    e.printStackTrace();
    return false;
   }
  }
  return true;
 }

 public boolean updateOrSaveUserManager(UserManager userManager)
   throws Exception {
  try{
   this.getHibernateTemplate().saveOrUpdate(userManager);
  }catch(Exception e){
   if(e != null){
    e.printStackTrace();
    return false;
   }
  }
  return true;
 }

 public int getCount() throws Exception {
  List list = this.getHibernateTemplate().find("select count(*) from UserManager");
  if(list != null && list.size() >=0){
   return Integer.parseInt(list.get(0).toString());
  }
  return 0;
 }


}

创建webRoot/WEB-INF/下创建applicationContext.xml文件

<?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.xsd">

	

	<!-- 采用c3p0数据源 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
		<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/×××××××"/>
		<property name="driverClass" value="com.mysql.jdbc.Driver"/>
		<property name="user" value="root"/>
		<property name="password" value="×××"/>
		<!-- 配置数据库连接池，最大连接数 -->
		<property name="maxPoolSize" value="20"/>
		<!-- 配置数据库连接池，最小连接数 -->
		<property name="minPoolSize" value="1"/>
		<!-- 指定数据库连接池的初始化连接数 -->
		<property name="initialPoolSize" value="1"/>
		<!-- 指定数据库连接池的连接的最大空闲时间 -->
		<property name="maxIdleTime" value="10"/>
	</bean>
  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"/>
		<property name="mappingResources">
			<list>
					<value>com/hrbkejia/bean/UserManager.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<!-- 
				采用MySql作为数据库系统，故使用MySQL方言
					<prop key="hibernate.hbm2ddl.auto">update</prop>
				 -->
				<prop key="show_sql">true</prop>
			<prop key="hibernate.hbm2ddl.auto">crate</prop>
				<prop key="hibernate.jdbc.batch_size">20</prop>
			</props>
		</property>
	</bean>
	


<!-- 定义事务管理器（声明式的事务） -->  
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

	<!-- 继承HibernateDaoSupport类，setSessionFactory()在HibernateDaoSupport类中已经做定义，所以不用重写setSessionFactory() -->
	<bean id="userManagerDaoBean" class="com.hrbkejia.dao.impl.UserManagerDaoImpl">
		<property name="sessionFactory" ref="sessionFactory"/>
	</bean>
	
	<!-- 用户登录Bean -->
	<bean id="login" class="com.hrbkejia.Action.UserLoginAction" scope="prototype" >
		<property name="userManagerDao" ref="userManagerDaoBean"/>
	</bean>
	
</beans>

在web.xml 添加启动spring 监听web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <!-- <display-name>Struts Blank</display-name> -->


	<listener>
 		<!-- spring2.0 监听-->
  		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 	</listener>
    <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>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

</web-app>

接下来引入struts2 对 spring 支持的插件“struts2-spring-plugin-2.3.15.3.jar ”

接下来配置struts2.xml文件，这里使用的通配符
