整合目标：使用spring的bean管理struts action service。

整合步骤：

一、加入spring

1、加入spring jar包

2、配置web.xml文件

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

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

3、加入spring配置文件

二、加入struts2

1、加入struts2 jar包

2、在web.xml配置

<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>

 

 

2、加入struts2 对spring支持的插件包struts2-spring-plugin-2.3.31.jar

3、加入struts2配置文件

4、创建一个简单service和action

package com.hy.service;

public class PersonService {
    public void save() {
        System.out.println("personService save...");
    }
}
package com.hy.action;

import com.hy.service.PersonService;

public class PersonAction {
    
    private PersonService personService;
    
    
    
    public PersonService getPersonService() {
        return personService;
    }



    public void setPersonService(PersonService personService) {
        this.personService = personService;
    }



    public String execute() {
        System.out.println("execute...");
        personService.save();
        return "success";
    }
}

5、在spring的配置文件中配置action和service

<bean name="personService" class="com.hy.service.PersonService"></bean>
    <bean name="personAction" class="com.hy.action.PersonAction" scope="prototype">
        <property name="personService" ref="personService"></property>
    </bean>

注意action的scope必须是prototype（非单例模式）

 

6、在struts2配置文件中配置action

<action name="person-save" class="personAction">
            <result>/success.jsp</result>
        </action>

7、创建测试页面

<%@ 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">person-save</a>
</body>
</html>
