如何优雅地包装controller的返回结果，Result类封装

 import java.io.Serializable;  public class Result implements Serializable {     private Integer code;     private String message;     private Object data;      //构造函数     public Result(Integer code, String message, Object data) {         this.code = code;         this.message = message;         this.data = data;     }      public Result(ResultCode resultCode) {         this.code = resultCode.getCode();         this.message = resultCode.getMessage();     }      public Result(ResultCode resultCode, Object data) {         this.code = resultCode.getCode();         this.message = resultCode.getMessage();         this.data = data;     }      //静态方法     public static Result success(){         Result result = new Result(ResultCode.SUCCESS);         return result;     }      public static Result success(Object data){         Result result = new Result(ResultCode.SUCCESS, data);         return result;     }      public static Result failure(ResultCode resultCode){         Result result = new Result(resultCode);         return result;     }      public static Result failure(ResultCode resultCode,Object data){         Result result = new Result(resultCode, data);         return result;     }       //Code和Msg的枚举类，一般情况情况下，code和message是一起的     public enum ResultCode {          SUCCESS(1, "成功"),         PARAM_IS_INVALID(1001, "参数无效"),         PARAM_IS_BLANK(1002, "参数为空"),         USER_NOT_LOGGED_IN(2001, "用户未登录"),         USER_LOGIN_ERROR(2002, "用户不存在或密码错误"),         USER_NOT_EXISTED(2003, "用户不存在");          private Integer code;         private String message;          public Integer getCode() {             return code;         }          public String getMessage() {             return message;         }          ResultCode(Integer code, String message) {             this.code = code;             this.message = message;         }     }   }
