返回格式如下：
{ "code": 200/400,
"msg": "成功"/"失败",
"total": n,
"data": [ {}，{}]}
1.在common中新增Result 类，代码如下
package com.xxx0523.common;
import lombok.Data;
@Data
public class Result {private int code;//编码 200.400private String msg;//成功、失败private Long total;//总记录数private Object data;//数据private String language;private static Result result (int code,String msg,String language,Long total,Object data){Result res =new Result();res.setLanguage(language);res.setData(data);res.setMsg(msg);res.setCode(code);res.setTotal(total);return res;}public static Result fail(){return result(400,"失败","中文",0L,null);}public static Result suc(){return result(200,"成功","中文",0L,null);}public static Result suc( Object data){return result(200,"成功","中文",0L,data);}public static Result suc( Object data,Long total){return result(200,"成功","中文",total,data);}}
2.更改用户控制类的代码
重启启动类并在在apipost中执行查看返回结果：
