springboot2.2x版本项目中配置全局异常处理

作者:互联网

说明

  1. AjaxException.class 为项目自定义的一个运行时异常类,若项目中未定义专用的异常类型,则可删除此异常处理方法;
  2. 在springboot的启动类需要配置@ComponentScan(basePackages = {“异常类的包路径”}),相对路径或绝对路径都可,否则异常处理类不生效;

核心异常处理类

package com.spin.common.multi.error;


import com.spin.common.base.ApiResult;
import com.spin.common.enums.ResponseEnum;
import com.spin.common.exceptions.AjaxException;
import lombok.extern.slf4j.Slf4j;
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 org.springframework.web.method.annotation.MethodArgumentTypeMismatchException;

import javax.servlet.http.HttpServletRequest;
import java.util.List;


@RestControllerAdvice
@Slf4j
public class BusinessExceptionHandler {

	 /**
     * 自定义异常类处理方法
     */
    @ExceptionHandler(AjaxException.class)
    public ApiResult<String> customExceptionHandler(HttpServletRequest request, AjaxException ex){
        ApiResult<String> apiResult=new ApiResult<>();
        apiResult.setMessage(ex.getMessage());
        apiResult.setSuccess(false);
        apiResult.setErrCode(String.valueOf(ex.getCode()));
        log.error("全局异常处理输入错误信息,请求路径:-------->{}",request.getRequestURL());
        log.error("全局异常处理输入错误信息,error:-------->",ex);
        return apiResult;
    }

    /**
     * 通用的接口映射异常处理方
     */
    @ExceptionHandler(Exception.class)
    protected ApiResult<String> commonExceptionHandler(HttpServletRequest request,Exception ex) {
        ApiResult<String> apiResult =new ApiResult<>();
        if (ex instanceof MethodArgumentNotValidException) {
            MethodArgumentNotValidException exception = (MethodArgumentNotValidException) ex;
            List<FieldError> fieldErrors = exception.getBindingResult().getFieldErrors();
            //多个错误,取第一个
            FieldError error = fieldErrors.get(0);
            String msg = error.getDefaultMessage();
            apiResult.setMessage(msg);
            apiResult.setSuccess(false);
            apiResult.setErrCode(ResponseEnum.RESPONSE_100000002.getCode().toString());
        }else if (ex instanceof MethodArgumentTypeMismatchException) {
            MethodArgumentTypeMismatchException exception = (MethodArgumentTypeMismatchException) ex;
            log.error("参数转换失败,方法:" + exception.getParameter().getMethod().getName() + ",参数:" + exception.getName()
                    + ",信息:" + exception.getLocalizedMessage());
            apiResult.setMessage(ResponseEnum.RESPONSE_402.getName());
            apiResult.setSuccess(false);
            apiResult.setErrCode(ResponseEnum.RESPONSE_402.getCode().toString());
        }else {
            apiResult.setErrCode(ResponseEnum.RESPONSE_500.getCode().toString());
            apiResult.setSuccess(false);
            apiResult.setMessage(ResponseEnum.RESPONSE_500.getName());
        }
        log.error("全局异常处理输入错误信息,请求路径:-------->{}",request.getRequestURL());
        log.error("全局异常处理输入错误信息,error:-------->",ex);
        return apiResult;
    }
}
