spring boot aop 方法请求参数日志打印

1.引入starter

            org.springframework.boot
            spring-boot-starter-aop

2.切面代码

package com.util;

import javax.servlet.http.HttpServletRequest;

import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import com.alibaba.fastjson.JSON;

    @Before("log()")
    public void exBefore(JoinPoint joinPoint){
        ServletRequestAttributes sra = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = sra.getRequest();
        logger.info("url:"+request.getRequestURL());

        logger.info("args:"+JSON.toJSONString(joinPoint.getArgs()));
    }
    
    @After("log()")
    public void exAfter(JoinPoint joinPoint){
        logger.info("class method:"+joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName()
                +"方法执行完毕！");
