SpringBoot中@RestControllerAdvice 全局異常處理的實現(xiàn)

更新時間：2025年06月18日 10:37:50 作者：Muscleheng

本文主要介紹了SpringBoot中@RestControllerAdvice 全局異常處理的實現(xiàn),通過定義統(tǒng)一響應格式、自定義異常類及測試驗證,確保接口異常時返回指定格式的提示信息,提升錯誤處理一致性

一、定義統(tǒng)一響應體

package com.zhh.demo.common.response;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.io.Serializable;

/**
 * @Description: 接口出參統(tǒng)一響應實體
 * @Author: zhaoheng
 * @CreateTime: 2022-08-05  16:27
 */
@Data
@ApiModel("接口出參統(tǒng)一響應實體")
public class Response<T> implements Serializable {
    private static final long serialVersionUID = 3692286106860121474L;

    @ApiModelProperty(value = "狀態(tài)碼")
    private String code;

    @ApiModelProperty(value = "說明")
    private String message;

    private T data;

    public Response(){}

    public Response(String code, String message) {
        this.code = code;
        this.message = message;
    }

    public Response(String code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }
}

package com.zhh.demo.common.response;

import lombok.Getter;

/**
 * @Description: 統(tǒng)一響應code和說明
 * @Author: zhaoheng
 * @CreateTime: 2022-08-05  16:42
 */
public enum ResponseCode {

    /** 通用碼 **/
    FAIL("-1", "系統(tǒng)錯誤"),
    OK("200", "成功"),

    /**
     * 參考阿里巴巴開發(fā)手冊
     * 錯誤碼為字符串類型，共5位，分兩部分組成：錯誤標識+4位數(shù)字編號。
     * 例：A0001，A1001，B0001，C0001... A、B、分別代表不通業(yè)務或者來源
     **/

    /** 參數(shù)校驗不通過 **/
    PARAMETER_CHECK_FAILS("A0001","參數(shù)校驗不通過"),

    /** 用戶相關 A1xxx **/
    USER_NAME_NONSTANDARD("A1002", "用戶名不合規(guī)");

    ResponseCode(String code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    @Getter
    private String code;

    @Getter
    private String msg;
}

package com.zhh.demo.common.response;

import com.zhh.demo.entity.common.ResponsePage;

import java.util.List;

/**
 * @Description: 接口統(tǒng)一響應實體構造類
 * @Author: zhaoheng
 * @CreateTime: 2022-08-05  16:37
 */
public class ResponseFactory {

    /**
     * 默認成功
     * @param t
     * @param <T>
     * @return
     */
    public static <T> Response<T> success(T t){
       return new Response<T>(ResponseCode.OK.getCode(),ResponseCode.OK.getMsg(),t);
    }

    /**
     * 成功
     * @param responseCode  響應code和說明
     * @param t
     * @param <T>
     * @return
     */
    public static <T> Response<T> success(ResponseCode responseCode, T t){
        return new Response<T>(responseCode.getCode(),responseCode.getMsg(),t);
    }

    /**
     * 成功
     * @param responseCode  響應code和說明
     * @return
     */
    public static <T> Response<T> success(ResponseCode responseCode){
        return new Response<T>(responseCode.getCode(),responseCode.getMsg());
    }

    /**
     * 默認失敗
     * @param <T>
     * @return
     */
    public static <T> Response<T> error(){
        return new Response<T>(ResponseCode.FAIL.getCode(),ResponseCode.FAIL.getMsg());
    }

    /**
     * 失敗
     * @param responseCode  響應code和說明
     * @param t
     * @param <T>
     * @return
     */
    public static <T> Response<T> error(ResponseCode responseCode, T t){
        return new Response<T>(responseCode.getCode(),responseCode.getMsg(),t);
    }

    /**
     * 失敗
     * @param responseCode  響應code和說明
     * @return
     */
    public static <T> Response<T> error(ResponseCode responseCode){
        return new Response<T>(responseCode.getCode(),responseCode.getMsg());
    }

    /**
     * 失敗
     * @param code  錯誤碼
     * @param msg   說明
     * @param t     響應數(shù)據(jù)
     * @param <T>
     * @return
     */
    public static <T> Response<T> error(String code, String msg, T t){
        return new Response<T>(code,msg,t);
    }

    /**
     * 失敗
     * @param code  錯誤碼
     * @param msg   說明
     * @return
     */
    public static <T> Response<T> error(String code, String msg){
        return new Response<T>(code,msg);
    }

    public static <T> ResponsePage pageResult(List<T> list, int total){
        return new ResponsePage<T>(list,total);
    }

}

二、定義全局異常處理類

package com.zhh.demo.common.exception;

import com.zhh.demo.common.response.Response;
import com.zhh.demo.common.response.ResponseCode;
import com.zhh.demo.common.response.ResponseFactory;
import lombok.extern.slf4j.Slf4j;
import org.springframework.validation.BindingResult;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

import java.util.List;

/**
 * @Description: 全局異常處理
 * @Author: zhaoheng
 * @CreateTime: 2022-08-05  17:33
 */
@Slf4j
@RestControllerAdvice
public class ExceptionHandle {

    /**
     * 處理Exception異常
     * @param exception 異常類型
     * @return
     */
    @ExceptionHandler(value = Exception.class)
    public Response<?> ExceptionHandle(Exception exception){
        log.error("系統(tǒng)出現(xiàn)異常：",exception);
        return ResponseFactory.error(ResponseCode.FAIL);
    }

    /**
     * 處理業(yè)務異常
     * @param exception 異常類型
     * @return
     */
    @ExceptionHandler(value = BaseException.class)
    public Response<?> BaseExceptionHandle(BaseExceptionexception){
        log.error("系統(tǒng)業(yè)務異常：",exception);
        return ResponseFactory.error(exception.getCode(),exception.getMsg());
    }

    /**
     * 入?yún)⑿ｒ灝惓?，校驗不通過，拋出異常信息
     * @param exception Valid 入?yún)⑿ｒ灝惓?
     * @return
     */
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public Response<?> methodArgumentNotValidExceptionHandle(MethodArgumentNotValidException exception){
        log.error("入?yún)⑿ｒ灢煌ㄟ^",exception);
        BindingResult bindingResult = exception.getBindingResult();
        List<FieldError> fieldErrorList = bindingResult.getFieldErrors();
        fieldErrorList.forEach(fieldError -> {
            log.info("字段：{}，message：{}",fieldError.getField(),fieldError.getDefaultMessage());
        });
        // 一個一個給調用方返回提示
        String message = fieldErrorList.get(0).getDefaultMessage();
        return ResponseFactory.error(ResponseCode.PARAMETER_CHECK_FAILS.getCode(), message);
    }

}

自定義異常

package com.zhh.demo.common.exception;

import com.zhh.demo.common.response.Response;
import com.zhh.demo.common.response.ResponseCode;
import lombok.Data;

/**
 * @Description: 異?；?
 * @Author: zhaoheng
 * @CreateTime: 2022-08-05  17:22
 */
@Data
public abstract class BaseException extends RuntimeException{

    /**
     * code碼
     */
    private String code;

    /**
     * 異常說明
     */
    private String msg;

    /**
     * 響應體
     */
    private Response response;

    public BaseException(String code, String msg) {
        super(msg);
        this.code = code;
        this.msg = msg;
        this.response = new Response(code,msg);
    }

    public BaseException(ResponseCode responseCode) {
        super(responseCode.getMsg());
        this.code = responseCode.getCode();
        this.msg = responseCode.getMsg();
        this.response = new Response(responseCode.getCode(),responseCode.getMsg());
    }
}

三、編寫接口測試效果

package com.zhh.demo.controller;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;


@Api(tags = "test-api")
@RequestMapping("/api/test")
@RestController
@Validated // 開啟入?yún)⑿ｒ?
public class TestController {
    
    @ApiOperation("異常測試")
    @PostMapping("/t1")
    public String test(){
        // 模擬異常
        new ArrayList<>().get(1);
        return "";
    }
}

經(jīng)過測試，接口拋出異常后會被異常處理類處理，并且給調用端返回指定格式的提示信息

{
  "code": "-1",
  "message": "系統(tǒng)錯誤",
  "data": null
}
