Spring 整合Structs

1  在web.xml 中做Spring的和Structs2 的基本配置

<?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">  <display-name></display-name>  <!--   配置Structs2 的核心过滤器 -->  <filter>      <filter-name>structs2</filter-name>      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter      </filter-class>  </filter>  <filter-mapping>         <filter-name>structs2</filter-name>         <url-pattern>/*</url-pattern>  </filter-mapping>    <!-- 配置Spring的配置文件 -->  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>          classpath:beans.xml  <!-- Spring 配置文件所在的位置classPath表示Src 下的路径 -->             <!--  可以配置多个   /WEB-INF/conf/conf.xml  用“,”隔开  表示在/WEB-INF/conf                 /conf.xml的路径下 -->       </param-value>  </context-param>  <listener>               <!-- 用Spring的contextLoaderListener 在项目启动时就加载Spring的配置文件  -->         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

2  创建action  

public class StudAction  extends ActionSupport{    private IStudService service;    private String name;         public String getName() {return name;}public void setName(String name) {this.name = name;}public IStudService getService() {return service;}public void setService(IStudService service) {this.service = service;}public String execute() throws Exception{                 System.err.println("这个是AtudAction"+getName());                 service.save();                 return SUCCESS;           }}

3 配置创建Structs2的类工厂

package com.wuyihuai.factory;import java.util.Map;import javax.servlet.ServletContext;import org.apache.struts2.ServletActionContext;import org.springframework.context.ApplicationContext;import org.springframework.web.context.WebApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;import com.opensymphony.xwork2.Action;import com.opensymphony.xwork2.ObjectFactory;/** * 让Structs2 不去创建action 而是去Spring中取需要的Action * */public class MyObjectFactory extends ObjectFactory{@Overridepublic Object buildBean(Class cls, Map<String, Object> ctx)throws Exception {// TODO Auto-generated method stubSystem.err.println("创建了。。。。。。"+cls+""+ctx);//判断cls 是不是Action 的孩子 如果不断地的话由于struct的过滤器在Spring的bean.xml中找不到会报错if(Action.class.isAssignableFrom(cls)){ //是Action Struct2不创建，由Spring的 创建ServletContext cs=ServletActionContext.getServletContext();//此类是以经封装好的beans.xml中的对象数据//ApplicationContext appCtx=(ApplicationContext) cs.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);  ApplicationContext appCtx=WebApplicationContextUtils.getWebApplicationContext(cs);Object o=appCtx.getBean(cls);return o;}else{  //不是Action 就有Struct2自己创建  return super.buildBean(cls, ctx);}}       }

4 配置Struct2.xml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>                <!-- 配置自己的类工厂 -->               <bean type="com.opensymphony.xwork2.ObjectFactory" name="wuyihuai"                  class="com.wuyihuai.factory.MyObjectFactory" />                  <constant name="struts.objectFactory" value="wuyihuai" ></constant>                 <!-- 配置Action类 -->                 <package name="wuyihuai" extends="struts-default">                 <action name="stud" class="com.wuyihuai.stud.StudAction">                            <result>/index.jsp</result>                    </action>               </package></struts>

5 配置Spring.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: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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">              <!-- 配置action bean -->       <bean id="studAction" class="com.wuyihuai.stud.StudAction" scope="prototype">            <property name="service" ref="studService"></property>       </bean>        <!-- 声明自己的dao和service -->       <bean id="studService" class="com.wuyihuai.service.StudServiceImpl">                 <property name="dao">                     <bean class="com.wuyihuai.dao.StudDaoJdbc"></bean>                 </property>       </bean></beans>
