Struts2+Spring+Hibernate 的xml方式的整合

使用xml方式整合三大框架

首先，新建一个web工程项目，整合的项目基本结构如下：(没有加入view层)

第二步，导入ss2h整合所需要的jar包，如下如：

第三步，编写持久层

1.定义好po类

package com.jjyy.ss2h.po;

/**

* @author Administrator--jiangyu--2014-9-12下午8:00:45

* po类

publicclass User {

private Integer id;

private String name;

private String phone;

public User() {

}

public User(Integer id, String name,String phone) {

super();

this.id = id;

this.name = name;

this.phone = phone;

}

public Integer getId() {

returnid;

}

publicvoid setId(Integer id) {

this.id = id;

}

public String getName() {

returnname;

}

publicvoid setName(String name) {

this.name = name;

}

public String getPhone() {

returnphone;

}

publicvoid setPhone(String phone) {

this.phone = phone;

}

2.编写对应的*.hbm.xml文件

<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC

"-//Hibernate/HibernateMapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.jjyy.ss2h.po" >

</id>

</class>

</hibernate-mapping>

第四步，编写服务层

1.定义服务层的接口（由于是简单的整合介绍，就只加入一个业务方法）

package com.jjyy.ss2h.service;

import com.jjyy.ss2h.po.User;

publicinterface UserService {

publicvoid save(User user);

}

2.编写实现服务层的接口类

package com.jjyy.ss2h.service.impl;

importorg.springframework.orm.hibernate3.HibernateTemplate;

importorg.springframework.transaction.annotation.Transactional;

import com.jjyy.ss2h.po.User;

importcom.jjyy.ss2h.service.UserService;

/**

* @author Administrator--jiangyu--2014-9-12下午8:04:33

* 接口的实现类

publicclass UserServiceImpl implements UserService{

/**

* 根据配置文件被动的等待注入

private HibernateTemplate hibernateTemplate;

public HibernateTemplategetHibernateTemplate() {

returnhibernateTemplate;

}

publicvoid setHibernateTemplate(HibernateTemplatehibernateTemplate) {

this.hibernateTemplate = hibernateTemplate;

}

/**

* 开启事务

@Transactional

publicvoid save(User user) {

hibernateTemplate.save(user);

}

第五步，编写表现层

package com.jjyy.ss2h.action;

import com.jjyy.ss2h.po.User;

importcom.jjyy.ss2h.service.UserService;

publicclass UserAction {

private UserService userService;

public UserService getUserService() {

returnuserService;

}

publicvoid setUserService(UserService userService) {

this.userService = userService;

}

private User user;

public User getUser() {

returnuser;

}

publicvoid setUser(User user) {

this.user = user;

}

public String save(){

userService.save(user);

returnnull;

}

第六步，xml文件的配置

1.web.xml文件的配置

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

<display-name></display-name>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext*.xml</param-value>

</context-param>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<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>

2.applicationContext-action.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

</beans>

3.applicationContext-service.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

<props>

<prop key="dialect">org.hibernate.dialect.MySQLDialect</prop>

<prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>

<prop key="hibernate.connection.url">jdbc:mysql://localhost:3306/test</prop>

<prop key="hibernate.hbm2ddl.auto">update</prop>

</props>

</property>

<list>

</list>

</property>

</bean>

</bean>

<tx:annotation-driven transaction-manager="txManager"/>

</beans>

4.struts.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC

"-//ApacheSoftware Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

</package>

</struts>

第六步，测试

启动tomcat服务器，到数据库查看是否生成了t_user3表，在tomcat服务器启动的时候，自动创建了表，这是框架内部帮我们完成的，然后测试一下业务方法save,在浏览器地址栏输入http://localhost:8080/ss2h_xml/userAction!save?user.name=jjyy，回车，在去数据库的t_user3表中查看是否插入了一条name为jjyy的记录。
