在平時的SSC程序修復，需要請搜索dsluntan.com 編碼過程中，返回給前端的數據都會統一規范起來，用一個泛型來作為響應對象
ServerResponse類
@JsonSerialize(include = ?JsonSerialize.Inclusion.NON_NULL)
//保證序列化json的時候,如果是null的對象,key也會消失
public class ServerResponse<T> implements Serializable{

????private int status;
????private String msg;
????private T data;

????private ServerResponse(int status){
????????this.status = status;
????}
????private ServerResponse(int status,T data){
????????this.status = status;
????????this.data = data;
????}

????private ServerResponse(int status,String msg,T data){
????????this.status = status;
????????this.msg = msg;
????????this.data = data;
????}

????private ServerResponse(int status,String msg){
????????this.status = status;
????????this.msg = msg;br/>????}
????@JsonIgnore
????//使之不在json序列化結果當中
????public boolean isSuccess(){
????????return this.status == ResponseCode.SUCCESS.getCode();
????}

????public int getStatus(){
????????return status;
????}
????public T getData(){
????????return data;
????}
????public String getMsg(){
????????return msg;
????}

????public static <T> ServerResponse<T> createBySuccess(){
????????return new ServerResponse<T>(ResponseCode.SUCCESS.getCode());
????}

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

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

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

????public static <T> ServerResponse<T> createByErrorMessage(String errorMessage){
????????return new ServerResponse<T>(ResponseCode.ERROR.getCode(),errorMessage);

????public static <T> ServerResponse<T> createByErrorCodeMessage(int errorCode,String errorMessage){
