统一响应结果（）

来源黑马，手敲下来 的，存一下防丢失

一般放在pojo目录下

Result.java

package com.example.pojo;

//统一响应结果封装类

public class Result {
    private Integer code;       //1成功，0失败
    private  String msg;        //提示信息
    private Object data;        //数据data

    public Result() {
    }

    public Result(Integer code, String msg, Object data) {
        this.code = code;
        this.msg = msg;
        this.data = data;
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

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

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }

    public static Result success(Object data){
        return new Result(1,"success",data);
    }
    public static Result success(){
        return new Result(1,"success",null);
    }
    public static Result error(String msg){
        return new Result(0,msg,null);
    }

    @Override
    public String toString() {
        return "Result{" +
                "code=" + code +
                ", msg='" + msg + '\'' +
                ", data=" + data +
                '}';
    }
}

 

或者

 

package com.example.pojo;

//统一响应结果封装类

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Result {
    private Integer code;       //1成功，0失败
    private  String msg;        //提示信息
    private Object data;        //数据data

//    查询   成功响应
    public static Result success(Object data){
        return new Result(1,"success",data);
    }
//    增删改      成功响应
    public static Result success(){
        return new Result(1,"success",null);
    }
//    失败响应
    public static Result error(String msg){
        return new Result(0,msg,null);
    }
}
