用struts2给的jar包解析json

用struts2给的jar包解析json

1 ,添加jar包struts2 - json - plugin - 2.3 . 1.2 .jar
2 .在json - struts.xml里配置
     < package  name = " myjson "    extends = " json-default " >
             < action name = " myjson "    class = " com.yjw.web.MyjsonAction " >
                 < result  type = " json " >
                     <!-- 找到根节点 -->
                 < param name = " root " > user </ param >
                 <!-- 浏览器不要缓存 -->
                 < param name = " noCache " > true </ param >
                 <!-- GZIP网页压缩协议，可以让传送更快，省流量 -->
                 < param name = " enableGZIP " > true </ param >
                     <!-- 排除action里是null的属性 -->
                 < param name = " excludeNullProperties " > true </ param >
                 </ result >
             </ action >
         </ package >
在MyjsonAction里写：
package  com.yjw.web;

import  com.opensymphony.xwork2.Action;

public   class  MyjsonAction   implements   Action  {
    private User user;
    private String x;

    public String execute() throws Exception {
        user = new  User();
        user.setId(1);
        user.setMoney(22);
        user.setName("tom");
        
        return "success";
    }

    public User getUser() {
        return user;
    }

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

    public String getX() {
        return x;
    }

    public void setX(String x) {
        this.x = x;
    }

}
