springboot-20-全局异常处理

springboot的全局异常处理

1. 新建一个类GlobalDefaultExceptionHandler
在class上注解  @ControllerAdvice

方法上注解 @ExceptionHandler(value=Exception.class)

这样程序出错, 就会返回默认配置的信息了

package com.iwhere.scrapy.exception;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.lang3.ArrayUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

import com.iwhere.scrapy.enums.PublicRespEnum;
import com.iwhere.scrapy.model.ResponseModel;

@ControllerAdvice
public class GlobalExceptionHandler {
    private static final Logger LOGGER = LoggerFactory.getLogger(GlobalExceptionHandler.class);

    @ExceptionHandler(Exception.class)
    @ResponseBody
    public ResponseModel defaultHandler(HttpServletRequest request, Exception exception) {
        StringBuffer url = request.getRequestURL();
        String params = request.getQueryString();
        // 发生地点
        int lineNum = 0;
        String className = null;
        String methodName = null;
        StackTraceElement[] st = exception.getStackTrace();
        if (ArrayUtils.isNotEmpty(st)) {
            lineNum = st[0].getLineNumber();
            className = st[0].getClassName();
            methodName = st[0].getMethodName();
        }

        String message = exception.getMessage();
        LOGGER.info("Exception: {}#{}() 在第{}行发生{}异常!!! url: {}, params: {}, info: {}", className, methodName, lineNum,
                exception.getClass().getName(), url, params, message);
        
        return ResponseModel.getModel(PublicRespEnum.RESCODE_500, message);
    }

}

其中ResponseModel 是一个统一返回模型
