action返回了success但是页面也没有局部刷新问题

首先：struts.xml文件没有错

<?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">
<struts>
    <constant name="struts.devMode" value="true" />
    <constant name="struts.ui.theme" value="simple"/>
   
    <package name="house-json"  extends = "json-default">
        <action name="login" class="com.pb.web.action.UserAction" method="login" >
            <result type="json" name="success" ></result>
            <result name="login" type="json"></result>
        </action>
    </package>
 
</struts>

其他地方貌似也没有什么错误！后来有仔细研究了一个上午，才发现，原来是UserAction里面的service使用了getter/setter方法，将其getter/setter方法去掉就好了。

package com.pb.web.action;

import java.util.Map;

import com.pb.base.action.BaseAction;
import com.pb.entity.HouseUser;
import com.pb.service.IUserService;
import com.pb.service.impl.UserServiceImpl;
import com.pb.util.Constant;

public class UserAction extends BaseAction {
    private HouseUser user;
    private IUserService service = new UserServiceImpl();
    private String msg;
   
    public String login(){
       System.out.println(user.getUsername()+"--"+user.getPassword());
       if(user!=null){
            Map<String, Object> map = service.login(user);
            user = (HouseUser)map.get("user");
            System.out.println(user.getUsername()+"==22222=="+user.getPassword());
            if(user!=null){
                System.out.println(user.getUsername()+"--进来session这块儿"+user.getPassword());
                this.session.put(Constant.LOGIN_USER, user);
                msg = "true";
                System.out.println("将返回success-------");
                return "success";
            }else{
                msg = (String)map.get("msg");
            }
        }
        System.out.println("将返回login");
        return LOGIN;
    }

//下面黄色部分删掉！！

   public IUserService getService() {
        return service;
    }

    public void setService(IUserService service) {
        this.service = service;
    } 

    public HouseUser getUser() {
        return user;
    }

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

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }
}
