1.首先加入maven依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2.写一个Http请求的aop

package com.example.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

@Aspect
@Component
public class HttpAspect {

    private final static Logger logger = LoggerFactory.getLogger(HttpAspect.class);

    @Pointcut("execution(public * com.example.controller.PersonController.getpersons())")
    public void log(){
    }

    @Before("log()")
    public void doBefore(JoinPoint joinPoint){
        logger.info("before!!!!!!!!!!!");
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        //url
        logger.info("url={}", request.getRequestURL());

        //method
        logger.info("method={}", request.getMethod());
        //ip
        logger.info("ip={}", request.getRemoteAddr());
        //类方法
        logger.info("class method={}", joinPoint.getSignature().getDeclaringTypeName() +", "+joinPoint.getSignature().getDeclaringTypeName()+".");
        //参数
        logger.info("url={}", joinPoint.getArgs());
    }

    @After("log()")
    public void doAfter(){
        logger.info("after!!!!!!!!!!!");
    }

    @AfterReturning(returning = "object",pointcut = "log()")
    public void doAfterReturning(Object object){
        logger.info("response={}",object.toString());
    }
}
