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)
;
@Getter
@Setter
private String msg;
@Getter
@Setter
private 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 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 @Setter
protected String tag;
/** 版本(方便接口调试) */
@Getter @Setter
protected 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 Result 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message
public FailBuilder message(String message) {
this.message = message;
return this;
}
public FailBuilder data(Object data) {
this.data = data;
return this;
}
@SuppressWarnings("unchecked")
public Result 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
