Struts2-Spring2.5_Hibernate3.2整合示例（简单注册）

博客分类：

Struts2-Spring-Hibernate整合

Hibernate AOP Struts Bean Spring

用Struts2-Spring2.5_Hibernate3.2实现一个非常非常简单的登录注册示例，附件中有项目的源码。加入相应的包后，就可以直接使用

项目的结构如下：

如附件中图片所示。

下面就一步一步进行说明

1)首先需要将Struts2、Spring2.5、Hibernate3.2所需要的jar包全部导入到项目中（本例中Hibernate3.2用的是MyEclipse自带的jar包，如何导入请查看其他博文，相关文章都有介绍）

2）配置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">
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
    <!-- 配置spring的监听器 -->
    <!-- 
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext*.xml</param-value>
    </context-param>
        如果Spring配置文件在/WEB-INF下，则用上面的内容进行配置，如果Spring配置文件直接放在工程src下，则用下面的
        内容进行配置
     -->
   <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath*:applicationContext-*.xml</param-value>
     </context-param>
     <!-- 开启监听 -->
  <listener>
         <listener-class>
             org.springframework.web.context.ContextLoaderListener
         </listener-class>
     </listener>
     <!-- 配置OpenSessionInViewFilter,必须在struts2监听之前 -->
    <filter>
       <filter-name>hibernateFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    </filter>
        <!-- 设置监听加载上下文 -->
  <filter>
      <filter-name>struts2</filter-name>
      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
     <filter-name>hibernateFilter</filter-name>
     <url-pattern>/*</url-pattern>
</filter-mapping>
  
  <filter-mapping>
  	<filter-name>struts2</filter-name>
  	<url-pattern>/*</url-pattern> 	
  </filter-mapping>
</web-app>

3)编写model类---User

package com.chenfei.model;

public class User {
   private Long id;
   private String username;
   private String password;
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 void setId(Long id) {
	this.id = id;
}
public Long getId() {
	return id;
}
}

4）编写Struts Action

package com.chenfei.action;

import com.chenfei.model.User;
import com.chenfei.service.LoginManager;
import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

	private User user;
	private LoginManager loginManager;

	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		if(loginManager.isLogin(user.getUsername(),user.getPassword()))
				return "success";
		else
			return "error";
	}
	public User getUser() {
		return user;
	}
	public void setUser(User user) {
		this.user = user;
	}
	public LoginManager getLoginManager() {
		return loginManager;
	}
	public void setLoginManager(LoginManager loginManager) {
		this.loginManager = loginManager;
	}
}

5)编写业务处理层（尽量是面向接口的编程）

package com.chenfei.service;

public interface LoginManager {
	public boolean isLogin(String username,String password);

}

上面是接口，下面是他的实现

package com.chenfei.service;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.chenfei.dao.UserDao;
import com.chenfei.model.User;

public class LoginManagerImpl implements LoginManager {
	private User user;//需要注入一个
	private UserDao userDao;
	public boolean isLogin(String username, String password) {
		// TODO Auto-generated method stub

		if(username!=null&&password!=null&&!username.equals("")&&!password.equals(""))
		{
			user.setUsername(username);
			user.setPassword(password);
			userDao.addUser(user);
			return true;
		}
		else
		{
			System.out.println("~~~~~~~~~~~~~~~~~~Wrong~~~~~~~~~~~~~~~~~");
			return false;
		}
	}
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}
	public UserDao getUserDao() {
		return userDao;
	}
	public User getUser() {
		return user;
	}
	public void setUser(User user) {
		this.user = user;
	}


}

6）编写Dao(尽量是面向接口的编程)

package com.chenfei.dao;

import com.chenfei.model.User;

public interface UserDao {
	public void addUser(User user);

}

上面是接口，下面是他的实现

package com.chenfei.dao;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.chenfei.model.User;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
//继承自HibernateDaoSupport 
	public void addUser(User user) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().save(user);

	}

}

7)为了测试AOP，编写一个简单的切面

package com.chenfei.aspect;

public class CheckUser {
	public void beforeLogin()
	{
		System.out.println("登录前的状态");
	}
	public void afterLogin()
	{
		System.out.println("登录后的状态");
	}

}

8）配置Struts的配置文件

<?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="default" extends="struts-default" >	
       <action name="login" class="loginAction">
          <result>/welcome.jsp</result>
          <result name="error">/error.jsp</result>
       </action>
    </package>      
</struts>

9）编写Spring的配置文件applicationContext-bean.xml

<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:tx="http://www.springframework.org/schema/tx" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    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/context/spring-context-2.5.xsd 
                        http://www.springframework.org/schema/aop 
                        http://www.springframework.org/schema/aop/spring-aop-2.5.xsd 
                        http://www.springframework.org/schema/tx 
                        http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> 
  
  <bean id="user" class="com.chenfei.model.User">
  </bean>

   <bean id="loginAction" class="com.chenfei.action.LoginAction"
        scope="prototype">
        <property name="loginManager" ref="loginManager"></property>
        <property name="user" ref="user">
        </property>
    </bean>
    
     <bean id="loginManager" class="com.chenfei.service.LoginManagerImpl">
          <property name="user" ref="user"></property>
          <property name="userDao" ref="userDao"></property> 
       </bean>
       
      <bean id="userDao" class="com.chenfei.dao.UserDaoImpl">
           <property name="sessionFactory" ref="sessionFactory"></property>
      </bean> 
       
       <!-- 显示AOP的用法 -->
       <bean id="checkUser" class="com.chenfei.aspect.CheckUser"></bean>
       <aop:config>
          <aop:aspect ref="checkUser">
               <aop:pointcut id="check" expression="execution(* *.isLogin(..))"/>
               <aop:before method="beforeLogin"  pointcut-ref="check"/>
               <aop:after method="afterLogin"  pointcut-ref="check"/>
          </aop:aspect>
       </aop:config> 
  
        <!-- 配置sessionFactory -->         
       <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
            <property name="configLocation">
                <value>classpath:hibernate.cfg.xml</value>
            </property>
       </bean>
       
        <!-- 事务管理器 --> 
      <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
         <property name="sessionFactory" ref="sessionFactory"/>
      </bean>
      
      <!-- 配置事务传播特性，本例仅以配置add开始的方法，事务传播特性为required -->
      <tx:advice id="txAdvice" transaction-manager="transactionManager">
          <tx:attributes>
              <tx:method name="add*" propagation="REQUIRED"/>
          </tx:attributes>
      </tx:advice>
      
      <!-- 配置哪些类的方法参与事务，当前com.chenfei.dao包中的子包，
                             类中所有方法需要，还需要参考tx:advice的设置 -->
      <aop:config>
         <aop:pointcut id="addManagerMethod" expression="execution(* com.chenfei.dao.*.*(..))"/><!--expression写的时候一定注意，否则会出现问题-->
         <aop:advisor advice-ref="txAdvice" pointcut-ref="addManagerMethod"/>
      </aop:config>

</beans>

10）编写Hibernate配置文件

hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

	<session-factory>
		<property name="connection.username">root</property>
		<property name="connection.url">
			jdbc:mysql://localhost:3306/user
		</property>
		<property name="dialect">
			org.hibernate.dialect.MySQLDialect
		</property>
		<property name="myeclipse.connection.profile">
			MyDriver
		</property>
		<property name="connection.password">113801</property>
		<property name="connection.driver_class">
			com.mysql.jdbc.Driver
		</property>
		<property name="current_session_context_class">thread</property>
		<mapping resource="./User.hbm.xml" />

	</session-factory>

</hibernate-configuration>

User.hbm.xml

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- 
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping package="com.chenfei.model">
    <class name="User" table="user">
        <id name="id" type="long">
            <column name="id" />
            <generator class="increment"></generator>
        </id>
        <property name="username" type="string">
            <column name="username" length="45" not-null="true" />
        </property>
        <property name="password" type="string">
            <column name="password" length="45" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

经过以上步骤，就可实现一个非常非常弱智的注册系统~~
