1、MagCode，错误码枚举类

package com.mgx.common.enums;import lombok.*;
import lombok.extern.slf4j.Slf4j;/*** 错误码* @author mgx*/
@Slf4j
@NoArgsConstructor
@AllArgsConstructor
public enum MsgCode {/*** 枚举标识，根据业务类型进行添加*/Code_200("操作成功",200),Code_400("错误请求", 400),Code_401("未授权", 401),Code_402("权限不足，请联系管理员", 402),Code_403("禁止请求", 403),Code_404("找不到相关内容", 404),Code_408("请求超时", 408),Code_410("该资源已删除", 410),Code_413("请求体过大", 413),Code_414("请求URI过长", 414),Code_415("不支持的媒体类型", 415),Code_500("系统错误", 500),Code_501("用户未登录", 501),Code_502("错误网关", 502),Code_503("服务不可用", 503),Code_504("网关超时", 504),Code_505("HTTP版本暂不支持", 505),Code_506("时间格式错误", 506)//自定义提示,Code_2001("参数错误", 2001),Code_2002("传入参数不符合条件", 2002),Code_2003("缺少请求参数", 2003),Code_2004("请求方式错误", 2004),Code_2005("sql语法错误", 2005),Code_2006("数据不存在", 2006),Code_2007("同步失败", 2007),Code_2008("添加失败", 2008),Code_2009("修改失败", 2009),Code_2010("删除失败", 2010),Code_2011("查询失败", 2011),Code_2012("评估失败", 2012),Code_2013("移出黑名单失败",2013),Code_2014("该车辆已在黑名单中",2014),Code_2015("请输入正确的手机号",2015),Code_2016("不支持的编码格式", 2016),Code_2017("不支持的解码格式", 2017),Code_2018("保存失败", 2018);@Getter@Setterprivate String msg;@Getter@Setterprivate Integer code;public static String getMessage(Integer code){MsgCode msgCode;try {msgCode = Enum.valueOf(MsgCode.class, "Code_" + code);} catch (IllegalArgumentException e) {log.error("传入枚举code错误！code：{}",code);return null;}return msgCode.getMsg();}}

2、统一返回结果类

package com.mgx.common.dto;import com.mgx.common.enums.MsgCode;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;import java.io.Serializable;/*** @author mgx*/
@AllArgsConstructor
@NoArgsConstructor
public class Result<T> implements Serializable {private static final long serialVersionUID = 1L;/** 成功与否 */@Getter protected boolean success;/** 结果代码 */@Getter protected Integer code;/** 消息 */@Getter protected String message;/** 标识（方便接口调试） */@Getter @Setterprotected String tag;/** 版本（方便接口调试） */@Getter @Setterprotected String version;/** 结果数据 */@Getter protected T data;/*** 不需指定code和message* @return SuccessBuilder*/public static SuccessBuilder success() {return new SuccessBuilder(Boolean.TRUE, MsgCode.Code_200.getCode(), MsgCode.Code_200.getMsg());}/*** 同时指定code和message* @return FailBuilder*/public static FailBuilder failure() {return new FailBuilder(Boolean.FALSE);}public static class SuccessBuilder {protected boolean success;protected Integer code;protected String message;protected String tag = "mgx";protected String version = "1.0";protected Object data;protected SuccessBuilder(boolean success, Integer code, String message) {this.success = success;this.code = code;this.message = message;}public SuccessBuilder data(Object data) {this.data = data;return this;}@SuppressWarnings("unchecked")public <T> Result<T> build() {return new Result<>(success, code, message, tag, version, (T) data);}}public static class FailBuilder {protected boolean success;protected Integer code;protected String message;protected String tag = "mgx";protected String version = "1.0";protected Object data;protected FailBuilder(boolean success) {this.success = success;}public FailBuilder code(Integer code) {this.code = code;String message = MsgCode.getMessage(code);if(message != null){this.message = message;}return this;}//如果调用code再调用此message方法，此message方法会覆盖code方法中set的messagepublic FailBuilder message(String message) {this.message = message;return this;}public FailBuilder data(Object data) {this.data = data;return this;}@SuppressWarnings("unchecked")public <T> Result<T> build() {return new Result<>(success, code, message, tag, version, (T) data);}}}

3、BooleanResult封装

package com.mgx.common.dto;import lombok.Data;import java.io.Serializable;/*** @author mgx*/
@Data
public class BooleanResult implements Serializable {private Boolean result;private String reason;public static BooleanResult success(){BooleanResult booleanResult = new BooleanResult();booleanResult.setResult(true);return booleanResult;}public static BooleanResult fail(){return fail(null);}public static BooleanResult fail(String reason){BooleanResult booleanResult = new BooleanResult();booleanResult.setResult(false);booleanResult.setReason(reason);return booleanResult;}}

4、结构展示
