Spring，负责对象对象创建
Struts，用Action处理请求
Spring与Struts框架整合，关键点：让struts框架action对象的创建，交给spring完成！

1.步骤：

引入jar文件
1）引入struts .jar相关文件

       commons-fileupload-1.2.2.jar
       commons-io-2.0.1.jar
       commons-lang3-3.1.jar
       freemarker-2.3.19.jar
       javassist-3.11.0.GA.jar
       ognl-3.0.5.jar
       struts2-core-2.3.4.1.jar
       xwork-core-2.3.4.1.jar

2）spring-core 相关jar文件

      commons-logging-1.1.3.jar
      spring-beans-3.2.5.RELEASE.jar
      spring-context-3.2.5.RELEASE.jar
      spring-core-3.2.5.RELEASE.jar
      spring-expression-3.2.5.RELEASE.jar

3）spring-web 支持jar包
      spring-web-3.2.5.RELEASE.jar 【Spring源码】
      struts2-spring-plugin-2.3.4.1.jar 【Struts源码】

4）配置XML
struts.xml    

     ----struts路径与action映射配置
bean.xml      

     ----spring ioc容器配置：先dao，再service，最后action
web.xml
    -----核心过滤器： 引入struts功能
    -----初始化spring的ioc容器

2.具体的代码

HelloDao.java

package com.zengmg.dao;public class HelloDao {public HelloDao(){System.out.println("Dao构造函数");}public void save(){System.out.println("Dao:保存成功！");}}

HelloService.java

package com.zengmg.service;import com.zengmg.dao.HelloDao;public class HelloService {public HelloService(){System.out.println("service构造函数");}//springIOC容器注入private HelloDao hdao;public void setHdao(HelloDao hdao) {this.hdao = hdao;}public void saveHello(){System.out.println("service:保存");hdao.save();}}

HelloAction.java

package com.zengmg.action;import com.opensymphony.xwork2.ActionSupport;
import com.zengmg.service.HelloService;public class HelloAction extends ActionSupport{private static final long serialVersionUID = 1L;//springIOC容器注入private HelloService hService;public void sethService(HelloService hService) {this.hService = hService;}@Overridepublic String execute() throws Exception {System.out.println("访问了helloAction");hService.saveHello();return SUCCESS;}
}

3、具体配置文件

bean-dao.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:p="http://www.springframework.org/schema/p"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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><bean id="helloDao" class="com.zengmg.dao.HelloDao" lazy-init="false"/></beans>     

bean-service.xml

bean-action.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:p="http://www.springframework.org/schema/p"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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><!-- 指定action多例 --><bean id="helloAction" class="com.zengmg.action.HelloAction" scope="prototype"><property name="hService" ref="helloService"/></bean>	</beans>     

struts.xml

<?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">

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://xmlns.jcp.org/xml/ns/javaee"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"id="WebApp_ID" version="3.1"><!-- 其他拦截器，其他拦截器要放在struts上面，要不然无效，因为struts拦截了所有请求 --><filter><filter-name>struts</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- spring配置 --><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/classes/bean-*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

4、运行效果

在启动时，就提示：

Dao构造函数
service构造函数

浏览器访问：http://localhost:8080/hellostruts2/hello

访问了helloAction
service:保存
Dao:保存成功！
