json转换的Bean
package com.example.demo.text;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import er;
/**

*/
public class t1 {
public static void main(String[] args) {
User user = new User(1,"⽼王","⽼王");
// 转成Json
String json = JSON.toJSONString(user);
System.out.println(json);
final Object parse = JSON.parse(json);
System.out.println(parse);
// 变成JavaBean对象
final User user1 = JSONObject.parseObject(json, User.class);
System.out.println(user1);
}
}
华丽的分割线：——————————————————————————————————————————————————————————————————————————————————————————————————————输出结果
{"id":1,"name":"⽼王","password":"⽼王"}
{"password":"⽼王","name":"⽼王","id":1}
User{id=1, name='⽼王', password='⽼王'}。
