Spring 整合 struts2

第一步:导入 spring 和 struts2 的 jar 包

其中 struts2-spring-plugin 是必不可少的

第二步:在 web.xml中配置信息

<?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">
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  <!-- needed for ContextLoaderListener -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>

	<!-- Bootstraps the root web application context before servlet initialization -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
</web-app>
           

第三步:写一个Action类和一个供测试的类

import com.loveyiyi.spring.struts2.service.PersonService;

public class PersonAction {
	
	private PersonService personService;
	
	public void setPersonService(PersonService personService) {
		this.personService = personService;
	}
	
	public String execute(){
		
		System.out.println("PersonAction's execute...");
		personService.save();
		return "success";
		
	}
}
           
package com.loveyiyi.spring.struts2.service;

public class PersonService {
	public void save(){
		System.out.println("PersonService's save...");
	}
}
           

第四步:配置 applicationContext.xml 文件

在 Spring 的 IOC 容器中配置 Struts2 的 Action

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">

	<bean id="personAction" class="com.loveyiyi.spring.struts2.action.PersonAction" scope="prototype">
		<property name="personService" ref="personService"></property>
	</bean>
	
	<bean id="personService" class="com.loveyiyi.spring.struts2.service.PersonService"></bean>
	
</beans>
           

注意: 在 IOC 容器中配置 Struts2 的 Action 时, 需要配置 scope 属性, 其值必须为 prototype

第五步:配置 struts2 的配置文件 struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">


<struts>
   	
    <package name="helloworld" extends="struts-default">
    
    	<action name="person-save" class="personAction">
    		<result>/success.jsp</result>
    	</action>
    	
    
    </package>
    
</struts>
           

action 节点的 class 属性需要指向 IOC 容器中该 bean 的 id

第六步:写 两个 jsp 进行测试

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<a href="person-save" target="_blank" rel="external nofollow" >Person Save</a>
</body>
</html>
           

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<h4>Success Page</h4>
</body>
</html>
