日志异常处理-spring aop注解

spring aop 可以在不破坏我们程序代码的前提下很好的对程序异常进行打印，网上也有很多这样的例子，我这里写的比较简单，只是针对程序出异常时进行见到的日志打印，代码比较简单。

异常日志处理类

package com.apt.study.exception;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import com.alibaba.fastjson.JSONObject;

@Component
@Aspect
public class ExceptionToJson {

    public Logger logger = LoggerFactory.getLogger(ExceptionToJson.class);

    @Pointcut("execution(* com.apt.study.service..*.*(..))")
    public void exceptionLog() {

    }

     @AfterThrowing(pointcut = "exceptionLog()", throwing="e")
     public  void doAfterThrowing(JoinPoint joinPoint, Throwable e) {
         try {
              logger.error("------->Error Class:" + e.getClass().getName());
             logger.error("------->Error msg:" + e.getMessage());
             logger.error("------->Error method:" + (joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()"));
             Object[] arguments = joinPoint.getArgs();
             if (arguments !=  null && arguments.length > 0) {
                 for ( int i = 0; i < arguments.length; i++) {
                   logger.error("------->args[" + i + "]: " + JSONObject.toJSONString(arguments[i]));
                 }
             }
        }  catch (Exception ex) {
            //记录本地异常日志
            logger.error("------->异常通知异常");
            logger.error("------->异常信息:{}", ex.getMessage());
        }

     }
}
