**1.先创建个枚举类**

import lombok.Getter;
    
    @Getter
    public enum ResultCode { 
    	//格式：A(),B(),C(); 末尾用分号
        RESULT_CODE_1(200, "操作成功"),
        RESULT_CODE_2(200, "操作失败");
    
        private int status;
        private String message;
    	
        ResultCode(int status, String message) { 
            this.status = status;
            this.message = message;
        }
    
    
    }

**2.再创建个实体**

public class ObjectResponse<T> { 
    
        private int status;
        private String message;
        private T data;
    
        public ObjectResponse(ResultCode code) { 
            this.status = code.getStatus();
            this.message = code.getMessage();
        }
    	
        @Override
        public String toString() { 
            return "ObjectResponse{" +
                    "status=" + status +
                    ", message='" + message + '\'' +
                    ", data=" + data +
                    '}';
        }
    
    	//测试
        public static void main(String[] args) { 
            ObjectResponse<Object> response = new ObjectResponse<>(ResultCode.RESULT_CODE_1);
            System.out.println(response.toString());
        }
    }
