SSH Java三大框架整合(Struts 2+Hibernate+Spring+mysql)

以前一直整合Struts 1.x,用Struts1.x做一些简单的项目。最近把Struts 2学了，感觉两者区别挺大的，自己学完就想整点东西出来，然后就把Spring 、Hibernate、Struts 2整合一下。

------------IT行业苦逼的孩子，希望大牛指导

一、集成环境

Struts 2  、Spring 2.5 、Hibernate 3.3

项目开始首先应该从官网上把这三个的框架下载了，方便开发的时候导入jar,以及阅读文档以及API。

二、开始整合

1.业务逻辑

使用这三种框架做一个MIS型系统的用户登录与注册。

2.添加Spring 2.5支持

（1）把Spring 2.5的jar文件添加到项目下WEB-INF下的lib文件夹

（2）配置spring所需要的配置文件beans.xml（将数据源配置好，此处使用mysql数据库）

配置文件如下：

<?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.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-2.5.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.5.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.5.xsd"><!-- 使用扫描的方式注入，把类交给spring管理--><context:component-scan base-package="zzuli.itstudio" /><!-- 此处的数据源类BasicDataSource可以自己选择c3p0等等 --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"><property name="driverClassName" value="com.mysql.jdbc.Driver"></property><property name="url"value="jdbc:mysql://localhost:3306/ssh2?useUnicode=true&characterEncoding=UTF-8"></property><property name="username" value="root"></property><property name="password" value="***"></property></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource"><ref bean="dataSource" /></property><property name="hibernateProperties"><value>hibernate.dialect=org.hibernate.dialect.MySQL5Dialect</value></property><property name="mappingResources"><list><value>zzuli/itstudio/ssh2/bean/User.hbm.xml</value></list></property></bean><!-- 对事务进行管理 --><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"/></bean><!--使用基于注解方式配置事务 --><tx:annotation-driven transaction-manager="txManager"/></beans>

上面文件需要注意的就是对spring管理事务的配置

（3）对业务bean的配置（User.java）

package zzuli.itstudio.ssh2.bean;public class User {private String username;private String password;private String sex;private int age;public User() {}public User(String username, String password, String sex, int age) {super();this.username = username;this.password = password;this.sex = sex;this.age = age;}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 getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}}

（4）添加Hibernate支持所需要的jar文件，并配置User.hbm.xml文件，文件配置如下：

<?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"><hibernate-mapping package="zzuli.itstudio.ssh2.bean"><class name="User"><id name="username" length="20"/><property name="password" length="20"/><property name="sex" length="20"/><property name="age" length="20"/></class></hibernate-mapping>

（5）书写业务接口UserService

package zzuli.itstudio.ssh2.service;import java.util.List;import zzuli.itstudio.ssh2.bean.User;public interface UserService {public void save(User user);public void update(User user);public User find(String username);public void delete(String... username);public List<User> list();  }

（6）书写业务实现类UserServiceBean

package zzuli.itstudio.ssh2.service.impl;import java.util.List;import javax.annotation.Resource;import org.hibernate.SessionFactory;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import zzuli.itstudio.ssh2.bean.User;import zzuli.itstudio.ssh2.service.UserService;@Service@Transactionalpublic class UserServiceBean implements UserService {@ResourceSessionFactory sessionFactory;public void delete(String... usernames) {for (String username : usernames) {sessionFactory.getCurrentSession().delete(sessionFactory.getCurrentSession().load(User.class,username));}}@Transactional(propagation = Propagation.NOT_SUPPORTED)public User find(String username) {return (User) sessionFactory.getCurrentSession().get(User.class, username);}@SuppressWarnings("unchecked")@Transactional(propagation = Propagation.NOT_SUPPORTED)public List<User> list() {return sessionFactory.getCurrentSession().createQuery("from User").list();}public void save(User user) {sessionFactory.getCurrentSession().persist(user);}public void update(User user) {sessionFactory.getCurrentSession().merge(user);}}

以上所述已经把Spring和Hibernate集成完毕，自己可以写Juint，进行测试

（7）添加Struts2的支持所需要的jar文件，并配置struts.xml,内容如下：

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><!-- 配置为默认视图主题 ,避免产生不必要的代码--><constant name="struts.ui.theme" value="simple"></constant><!-- 用spring替换掉struts2默认的对象工厂 --><constant name="struts.objectFactory" value="spring"/><!-- 定义struts2命名空间 --><package name="user" namespace="/user" extends="struts-default"><!-- 这个action使用通配符的方式配置 --><action name="user_*" class="addUserAction" method="{1}"><result name="add">/WEB-INF/addUser.jsp</result><result name="message">/WEB-INF/message.jsp</result></action><action name="login_*" class="loginAction" method="{1}"><result name="login">/WEB-INF/login.jsp</result><result name="message">/WEB-INF/message.jsp</result></action></package></struts>    

（8）在web.xml中添加对Spring容器的支持，以及配置struts。详细内容如下：

<?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"><!-- 指定spring配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:beans.xml</param-value></context-param><!-- 对spring容器进行实例化 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置struts2的支持 --><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>

（9）编写登录页面login.jsp，并编写相应的Action

login.jsp部分内容如下：

<body><s:form action="login_login" namespace="/user" method="post">用户名：<s:textfield name="user.username"></s:textfield><br/>密码：<s:textfield name="user.password"></s:textfield><br/><input type="submit" value="登录"/>  <input type="reset" value="重置"/><br/></s:form></body>

LoginAction.java

package zzuli.itstudio.ssh2.action;import javax.annotation.Resource;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import com.opensymphony.xwork2.ActionContext;import zzuli.itstudio.ssh2.bean.User;import zzuli.itstudio.ssh2.service.UserService;@Controller @Scope("prototype")public class LoginAction {@Resource UserService userService;private User user;public User getUser() {return user;}public void setUser(User user) {this.user = user;}//添加界面public String input(){return "login";}public String login(){//从前台页面获取数据System.out.println(user.getUsername());System.out.println(user.getPassword());//业务逻辑User user2 = userService.find(user.getUsername());if(user2 != null && !("").equals(user.getUsername()))ActionContext.getContext().put("message", "登录成功！");elseActionContext.getContext().put("message", "登录失败！");return "message";}}

返回页面如下（message.jsp）：

<body><h1><s:property value="#request.message"/></h1></body>

（10）编写用户注册addUser.jsp以及相应的Action

addUser.jsp

<body><s:form action="user_add" namespace="/user" method="post">用户名:<s:textfield name="user.username"></s:textfield><br/>密码：<s:textfield name="user.password"></s:textfield><br/>性别：<s:textfield name="user.sex"></s:textfield><br/>年龄：<s:textfield name="user.age"></s:textfield><br/><input type="submit" value="注册"/></s:form></body>

AddUserAction.java

package zzuli.itstudio.ssh2.action;import javax.annotation.Resource;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import com.opensymphony.xwork2.ActionContext;import zzuli.itstudio.ssh2.bean.User;import zzuli.itstudio.ssh2.service.UserService;@Controller @Scope("prototype")public class AddUserAction {@Resource UserService userService;private User user;public User getUser() {return user;}public void setUser(User user) {this.user = user;}//添加界面public String addUI(){return "add";}public String add(){userService.save(user);//保存之后向前台返回一个信息ActionContext.getContext().put("message", "注册成功！");return "message";}}

至此三大框架的简单集成已经结束。可以再自己浏览器下进行测试。

进入登录界面输入：http://localhost:8080/SSH2/user/login_input.action

进入注册界面输入：http://localhost:8080/SSH2/user/user_addUI.action
