	</build>

3. 新建applicationContext.xml

<?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:aop="http://www.springframework.org/schema/aop"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        
	http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd        
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
	
	<context:component-scan base-package="com.lq" />

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver">
		</property>
		<property name="url" value="jdbc:mysql://127.0.0.1:3306/test">
		</property>
		<property name="username" value="root"></property>
		<property name="password" value="root"></property>
	</bean>
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
				<prop key="hibernate.show_sql">
					true
				</prop>
			</props>
		</property>
		
		<property name="mappingResources"> 
			<list> 
				<value>hbm/User.hbm.xml</value> 
			</list>
		</property>

	</bean>
	<!-- 配置事务管理器（采用注解的方式） -->
	<bean id="txManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<!-- 开启注解事务 -->
	<tx:annotation-driven transaction-manager="txManager" />
</beans>

4. web.xml配置spring监听器和struts2过滤器

<!-- 配置Spring的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
     
    <!-- 指定Spring配置文件所在路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param> 
  	<!-- 配置Struts2过滤器 -->
    <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>

5.新建struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
    <constant name="struts.devMode" value="false" />
    <!-- <constant name="struts.objectFactory" value="spring" /> -->
    <package name="default" namespace="/" extends="struts-default">
        <action name="user" class="com.lq.action.UserAction">
            <result name="success">/index.jsp</result>
        </action>
    </package> 
</struts>

6.创建action

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import com.lq.model.User;
import com.lq.service.IUserService;
import com.opensymphony.xwork2.ActionSupport;
@Controller
public class UserAction extends ActionSupport{
	private User user;
	@Autowired
	private IUserService userService;
	
	@Override
	public String execute() throws Exception {
		userService.login();
		return "success";
	}

	public IUserService getUserService() {
		return userService;
	}

	public void setUserService(IUserService userService) {
		this.userService = userService;
	}

	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}
	
}

 7.创建service 

public interface IUserService {
	public boolean login();
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.lq.dao.UserDao;
/**
 * 
 * @author haowl
 *@Transactional 可以作用于接口、接口方法、类以及类方法上。当作用于类上时，
 * 该类的所有 public 方法将都具有该类型的事务属性
 * 该属性用于设置需要进行回滚的异常类数组，当方法中抛出指定异常数组中的异常时，则进行事务回滚。例如：
         指定单一异常类：@Transactional(rollbackFor=RuntimeException.class)
        指定多个异常类：@Transactional(rollbackFor={RuntimeException.class, Exception.class})
 */
@Service
@Transactional
public class UserServiceImpl implements IUserService{
	@Autowired
	private UserDao userDao;
	
	@Override
	public boolean login() {
		return userDao.login();
	}

	public UserDao getUserDao() {
		return userDao;
	}

	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}
	
}

 8.创建dao 

import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import com.lq.model.User;

@Repository
public class UserDao extends HibernateDaoSupport{
	
	public boolean login() {
	    Session session =getSessionFactory().openSession();
	    String sql="select * from tb_users where username=?";
	    User user = (User)session.createSQLQuery(sql).addEntity(User.class).setParameter(0, "123456").uniqueResult();
		System.out.println(user.getLikes());
	    return false;
	}
	//按照名称找到sessionFacotry注入给父类的sessionFacotry属性
	@Resource
	public void setSessionFacotry(SessionFactory sessionFacotry) {  
        super.setSessionFactory(sessionFacotry);  
    } 

}

 9.创建实体类和与之对应的hbm文件

public class User implements java.io.Serializable {
    private String username;
    private String password;
    private String email;
    private String sex;
    private String likes;
    
	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 String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getLikes() {
		return likes;
	}
	public void setLikes(String likes) {
		this.likes = likes;
	}
    
}

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.lq.model.User" table="tb_users" >
        <id name="username" type="string">
            <column name="username" />
            <generator class="uuid" />
        </id>
        <property name="password" type="string">
            <column name="password" length="32" />
        </property>
        <property name="email" type="string">
            <column name="email" length="32" />
        </property>
        <property name="sex" type="string">
            <column name="sex" length="32" />
        </property>
        <property name="likes" type="string">
            <column name="likes" length="32" />
        </property>
    </class>
</hibernate-mapping>

注：hbm文件放在resources下
