封装类如下
HTTP状态码枚举类
package com.yyl.model.common.enums;
public enum AppHttpCodeEnum
// 成功段固定为200
SUCCESS(200,"操作成功"),
// 登录段1~50
NEED_LOGIN(1,"需要登录后操作"),
LOGIN_PASSWORD_ERROR(2,"密码错误"),
// TOKEN50~100
TOKEN_INVALID(50,"无效的TOKEN"),
TOKEN_EXPIRE(51,"TOKEN已过期"),
TOKEN_REQUIRE(52,"TOKEN是必须的"),
// SIGN验签 100~120
SIGN_INVALID(100,"无效的SIGN"),
SIG_TIMEOUT(101,"SIGN已过期"),
// 参数错误 500~1000
PARAM_REQUIRE(500,"缺少参数"),
PARAM_INVALID(501,"无效参数"),
PARAM_IMAGE_FORMAT_ERROR(502,"图片格式有误"),
SERVER_ERROR(503,"服务器内部错误"),
// 数据错误 1000~2000
DATA_EXIST(1000,"数据已经存在"),
AP_USER_DATA_NOT_EXIST(1001,"ApUser数据不存在"),
DATA_NOT_EXIST(1002,"数据不存在"),
// 数据错误 3000~3500
NO_OPERATOR_AUTH(3000,"无权限操作"),
NEED_ADMIND(3001,"需要管理员权限"),
// 自媒体文章错误 3501~3600
MATERIASL_REFERENCE_FAIL(3501,"素材引用失效");
int code;
String errorMessage;
AppHttpCodeEnum(int code, String errorMessage)
this.code = code;
this.errorMessage = errorMessage;
public int getCode()
return code;
public String getErrorMessage()
return errorMessage;
通用的结果返回类
package com.yyl.model.common.dtos;
import com.alibaba.fastjson.JSON;
import com.heima.model.common.enums.AppHttpCodeEnum;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* 通用的结果返回类
* @param <T>
*/
public class ResponseResult<T> implements Serializable
private String host;
private Integer code;
private String errorMessage;
private T data;
public ResponseResult()
this.code = 200;
public ResponseResult(Integer code, T data)
this.code = code;
this.data = data;
public ResponseResult(Integer code, String msg, T data)
this.code = code;
this.errorMessage = msg;
this.data = data;
public ResponseResult(Integer code, String msg)
this.code = code;
this.errorMessage = msg;
public static ResponseResult errorResult(int code, String msg)
ResponseResult result = new ResponseResult();
return result.error(code, msg);
public static ResponseResult okResult(int code, String msg)
ResponseResult result = new ResponseResult();
return result.ok(code, null, msg);
public static ResponseResult okResult(Object data)
ResponseResult result = setAppHttpCodeEnum(AppHttpCodeEnum.SUCCESS, AppHttpCodeEnum.SUCCESS.getErrorMessage());
if(data!=null)
result.setData(data);
return result;
public static ResponseResult errorResult(AppHttpCodeEnum enums)
return setAppHttpCodeEnum(enums,enums.getErrorMessage());
public static ResponseResult errorResult(AppHttpCodeEnum enums, String errorMessage)
return setAppHttpCodeEnum(enums,errorMessage);
public static ResponseResult setAppHttpCodeEnum(AppHttpCodeEnum enums)
return okResult(enums.getCode(),enums.getErrorMessage());
private static ResponseResult setAppHttpCodeEnum(AppHttpCodeEnum enums, String errorMessage)
return okResult(enums.getCode(),errorMessage);
public ResponseResult<?> error(Integer code, String msg)
this.code = code;
this.errorMessage = msg;
return this;
public ResponseResult<?> ok(Integer code, T data)
this.code = code;
this.data = data;
return this;
public ResponseResult<?> ok(Integer code, T data, String msg)
this.code = code;
this.data = data;
this.errorMessage = msg;
return this;
public ResponseResult<?> ok(T data)
this.data = data;
return this;
public Integer getCode()
return code;
public void setCode(Integer code)
this.code = code;
public String getErrorMessage()
return errorMessage;
public void setErrorMessage(String errorMessage)
this.errorMessage = errorMessage;
public T getData()
return data;
public void setData(T data)
this.data = data;
public String getHost()
return host;
public void setHost(String host)
this.host = host;
测试一下
写一个main方法在里面，测试各个功能：
import com.alibaba.fastjson.JSON;
import com.heima.model.common.enums.AppHttpCodeEnum;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
业务功能......
*/
public static void main(String[] args)
//前置
System.out.println("********************* 状态信息 *************************");
System.out.println("成功========================");
AppHttpCodeEnum success = AppHttpCodeEnum.SUCCESS;
System.out.println(success.getCode());
System.out.println(success.getErrorMessage());
System.out.println("需要登陆========================");
AppHttpCodeEnum login = AppHttpCodeEnum.NEED_LOGIN;
System.out.println(login.getCode());
System.out.println(login.getErrorMessage());
//查询一个对象
System.out.println("********************* 查询一个对象 *************************");
Map map = new HashMap();
map.put("name", "林若溪");
map.put("age", 18);
ResponseResult result = ResponseResult.okResult(map);
System.out.println(JSON.toJSONString(result));
//新增，修改，删除 在项目中统一返回成功即可
System.out.println("********************* 新增，修改，删除 *************************");
ResponseResult result1 = ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);
System.out.println(JSON.toJSONString(result1));
//根据不用的业务返回不同的提示信息 比如：当前操作需要登录、参数错误
System.out.println("********************* 根据不用的业务返回不同的提示信息 *************************");
ResponseResult result2 = ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN, "自定义提示信息：啦啦啦啦啦啦啦啦啦");
System.out.println(JSON.toJSONString(result2));
//查询分页信息
System.out.println("********************* 查询分页信息 *************************");
PageResponseResult responseResult = new PageResponseResult(1,2,10);
List list = new ArrayList();
list.add("玉雪凝");
list.add("苏映雪");
list.add("雪凝");
list.add("苏雪");
list.add("玉凝");
list.add("苏映");
responseResult.setData(list);
System.out.println(JSON.toJSONString(responseResult));
运行结果如下
