高可用复用对象的设计

在web开发中，现在比较流行的是从控制层往前台返回json格式的数据，而若每次的返回都设计一个类的话，不方便使用的同时也会显得很臃肿。因此可以设计一个高可用复用的对象，来统一返回的json格式的数据。

//字段为空的话，不序列化进json数据，即不像前台返回空的值。@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)public class ServerResponse<T> {    private T  data;    private String msg;    private int code;    public T getData() {        return data;    }    public String getMsg() {        return msg;    }    public int getCode() {        return code;    }    private ServerResponse(int code){         this.code=code;    }    private ServerResponse(int code,String msg){        this.code=code;        this.msg=msg;    }    private ServerResponse(int code ,String msg,T data){        this.code=code;        this.msg=msg;        this.data = data;    }    public static void main(String[] args) {        System.out.println(createBySuccess("222") );    }    private ServerResponse(int coede ,T data){        this.code=code;        this.data=data;    }    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){        return new ServerResponse<T>(errorCode,errorMessage);    }        //不返回是否成功这个标志位，即在向前台返回的数据中不包含：isSuccess:true 或isSuccess:false    @JsonIgnore    public boolean isSuccess(){        return this.code == ResponseCode.SUCCESS.getCode();    }    @Override    public String toString() {        return "ServerResponse{" +                "data=" + data +                ", msg='" + msg + '\'' +                ", code=" + code +                '}';    }}
