High multiplexing response class:

package com.repairsystem.repairsys.common;

import org.codehaus.jackson.annotate.JsonIgnore;
import org.codehaus.jackson.map.annotate.JsonSerialize;

/ **
* highly multiplexed service response object
* @param <T>
* /
@JsonSerialize (= the include JsonSerialize.Inclusion.NON_NULL) // json serialization time, if a null object, key will disappear
public class ServerResponse <T> {
Private int Status;
Private String MSG;
Private Data T;

private ServerResponse(int status){
this.status = status;
}
private ServerResponse(int status, String msg){
this.status = status;
this.msg = msg;
}
private ServerResponse(int status, String msg, T data){
this.status = status;
this.msg = msg;
this.data = data;
}
private ServerResponse(int status, T data){
this.status = status;
this.data = data;
}
@JsonIgnore //使之不在json序列化的结果当中
public boolean isSuccess(){
return this.status == ResponseCode.SUCCESS.getCode();
}

public int getStatus() {
return status;
}

public String getMsg() {
return msg;
}

public T getData() {
return data;
}

public static <T> ServerResponse<T> createBySuccess(){
return new ServerResponse(ResponseCode.SUCCESS.getCode());
}
public static <T> ServerResponse<T> createBySuccessMassage(String msg){
return new ServerResponse(ResponseCode.SUCCESS.getCode(),msg);
}
public static <T> ServerResponse<T> createBySuccess(T data){

public static <T> ServerResponse<T> createBySuccess(String msg,T data){

}
}

Its role is to json format data into a desired sequence as a generic class T, such a method of providing a record of such objects, as the server's response.

Such as:

"status": 0,
"msg": "登录成功！",
"data":{
"adminId": 1,
"adminNum": "978978",
"adminPassword": "",
"adminName": "zplw",
"adminTel": "12345678900",
"adminImg": "css/img/content/p3.jpg"
},
"success": true

"Status": 0,
"msg": "login is successful!",
"the Data": {
"userId": 1,
"userNum": "978.24 thousand",
"the userPassword": "",
"userName": "ZZZZ",
"userBirth": "1998-03-02 in",
"userTel": "91,938,989,189",
"userImg": null
},
"Success": to true

use of technology:
the server: springboot + mybatis + websocket
front end: html + css + bootstrap JQ + ajax +
