本文链接：https://blog.youkuaiyun.com/qq_37665834/article/details/84342027

本项目使用struts2为2.3 .2，spring为5.0.8
导入基本的struts2和spring的基本jar包，该包的作用https://blog.youkuaiyun.com/mjl960108/article/details/53541707?utm_source=blogxgwz6
引入struts2-spring-plugin-x.x.x.jar，这个包在Struts2的lib中

创建User类

package com.zg.sxsh.spring;

public class User {
    private String name;
    private String password;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

创建AddUser类

package com.zg.sxsh.spring;

import com.opensymphony.xwork2.ActionSupport;

public class AddUser extends ActionSupport {
    private User user;

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    @Override
    public String execute() throws Exception {
        System.out.println(user.getName());
        System.out.println(user.getPassword());
        return SUCCESS;
    }
}

配置web.xml文件，struts2与spring的整合要添加 <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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_4_0.xsd"
           version="3.0">
    <display-name>SXSH</display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <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>
</web-app>

配置applicationContext.xml文件

<?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.xsd">
    <bean name="addUser" class="com.zg.sxsh.spring.AddUser">
        <property name="user" ref="user"></property>
    </bean>
    <bean name="user" class="com.zg.sxsh.spring.User">
        <property name="name" value="lulu"></property>
        <property name="password" value="1234"></property>
    </bean>
</beans>

配置struts.xml文件

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

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
