springboot中500錯(cuò)誤的問(wèn)題解決

更新時(shí)間：2025年11月07日 09:29:36 作者：智能創(chuàng)新者

本文詳細(xì)介紹了Spring Boot中處理500錯(cuò)誤的幾種方法,包括自定義異常、可預(yù)知異常和不可預(yù)知異常的分類處理,具有一定的參考價(jià)值,感興趣的可以了解一下

ResultCode

/**
 * Created by mrt on 2018/3/5.
 * 10000-- 通用錯(cuò)誤代碼
 * 22000-- 媒資錯(cuò)誤代碼
 * 23000-- 用戶中心錯(cuò)誤代碼
 * 24000-- cms錯(cuò)誤代碼
 * 25000-- 文件系統(tǒng)
 */
public interface ResultCode {
    //操作是否成功,true為成功，false操作失敗
    boolean success();
    //操作代碼
    int code();
    //提示信息
    String message();

}

ResponseResult

import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;

@Data
@ToString
@NoArgsConstructor
public class ResponseResult implements Response {

    //操作是否成功
    boolean success = SUCCESS;

    //操作代碼
    int code = SUCCESS_CODE;

    //提示信息
    String message;

    public ResponseResult(ResultCode resultCode) {
        this.success = resultCode.success();
        this.code = resultCode.code();
        this.message = resultCode.message();
    }

    public static ResponseResult SUCCESS() {
        return new ResponseResult(CommonCode.SUCCESS);
    }

    public static ResponseResult FAIL() {
        return new ResponseResult(CommonCode.FAIL);
    }

}

自定義異常類

import com.xuecheng.framework.model.response.ResultCode;

/**
 * 自定義異常
 *
 * @author john
 * @date 2019/12/20 - 10:57
 */
public class CustomException extends RuntimeException {
    private ResultCode resultCode;

    public CustomException(ResultCode resultCode) {
        //異常信息為錯(cuò)誤代碼+異常信息
        super("錯(cuò)誤代碼：" + resultCode.code() + "錯(cuò)誤信息：" + resultCode.message());
        this.resultCode = resultCode;
    }

    public ResultCode getResultCode() {
        return this.resultCode;
    }
}

CommonCode (自定義異常信息返回?cái)?shù)據(jù)枚舉類)

import lombok.ToString;

@ToString
public enum CommonCode implements ResultCode{
    INVALID_METHOD(false,10004,"非法方法！"),
    INVALID_PARAM(false,10003,"非法參數(shù)！"),
    SUCCESS(true,10000,"操作成功！"),
    FAIL(false,11111,"操作失??！"),
    UNAUTHENTICATED(false,10001,"此操作需要登陸系統(tǒng)！"),
    UNAUTHORISE(false,10002,"權(quán)限不足，無(wú)權(quán)操作！"),
    SERVER_ERROR(false,99999,"抱歉，系統(tǒng)繁忙，請(qǐng)稍后重試！");
//    private static ImmutableMap<Integer, CommonCode> codes ;
    //操作是否成功
    boolean success;
    //操作代碼
    int code;
    //提示信息
    String message;
    private CommonCode(boolean success,int code, String message){
        this.success = success;
        this.code = code;
        this.message = message;
    }

    @Override
    public boolean success() {
        return success;
    }
    @Override
    public int code() {
        return code;
    }

    @Override
    public String message() {
        return message;
    }


}

異常處理（包含自定義異常和不可預(yù)見(jiàn)異常和可預(yù)見(jiàn)異常）

import com.google.common.collect.ImmutableMap;
import com.xuecheng.framework.model.response.CommonCode;
import com.xuecheng.framework.model.response.ResponseResult;
import com.xuecheng.framework.model.response.ResultCode;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.web.HttpRequestMethodNotSupportedException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @author john
 * @date 2019/12/20 - 11:01
 */
@Slf4j
@ControllerAdvice
public class ExceptionCatch {
    //使用EXCEPTIONS存放異常類型和錯(cuò)誤代碼的映射，ImmutableMap的特點(diǎn)的一旦創(chuàng)建不可改變，并且線程安全
    private static ImmutableMap<Class<? extends Throwable>, ResultCode> EXCEPTIONS;
    //使用builder來(lái)構(gòu)建一個(gè)異常類型和錯(cuò)誤代碼的異常
    protected static ImmutableMap.Builder<Class<? extends Throwable>, ResultCode> builder =
            ImmutableMap.builder();

    static {
        //在這里加入一些基礎(chǔ)的異常類型判斷---異常存在非自定義異常
        // 參數(shù)異常
        // 請(qǐng)求方法異常
        builder.put(HttpMessageNotReadableException.class, CommonCode.INVALID_PARAM);
        builder.put(HttpRequestMethodNotSupportedException.class, CommonCode.INVALID_METHOD);
    }


    //捕獲   CustomException異常
    @ExceptionHandler(CustomException.class)
    @ResponseBody
    public ResponseResult customException(CustomException e) {
        log.error("catch   exception   :   {}\r\nexception:   ", e.getMessage(), e);
        ResultCode resultCode = e.getResultCode();
        return new ResponseResult(resultCode);
    }


    //捕獲Exception異常---非自定義異常
    @ResponseBody
    @ExceptionHandler(Exception.class)
    public ResponseResult exception(Exception e) {
        log.error("catch   exception   :   {}\r\nexception:   ", e.getMessage(), e);
        if (EXCEPTIONS == null)
            EXCEPTIONS = builder.build();
        // 查看異常是否被定義返回格式---沒(méi)有就返回默認(rèn)錯(cuò)誤格式
        final ResultCode resultCode = EXCEPTIONS.get(e.getClass());
        final ResponseResult responseResult;
        if (resultCode != null) {
            responseResult = new ResponseResult(resultCode);
        } else {
            responseResult = new ResponseResult(CommonCode.SERVER_ERROR);
        }
        return responseResult;
    }
}
