本文介绍如何使用Spring AOP实现控制器方法的日志记录功能，包括请求URL、方法、客户端IP等信息，并展示了如何通过环绕通知处理请求过程。

1.引入相关依赖

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

2.创建TimeAspect类

@Aspect
@Component
public class TimeAspect {

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

    @Pointcut("execution(public * com.springboot.springbootlearning.controller.TestController.*(..))")
    public void log(){}

    @Before("log()")
    public void doBefore(JoinPoint joinPoint){
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        //url
        logger.info("url={}",request.getRequestURI());
        //method
        logger.info("method={}",request.getMethod());
        //ip
        logger.info("ip={}",request.getRemoteAddr());
        //类方法
        logger.info("class_method={}",joinPoint.getSignature().getDeclaringType()+"."+joinPoint.getSignature().getName());
        //参数
        logger.info("args={}",joinPoint.getArgs());
    }

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

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

使用环绕通知实现

package com.lzc.aop.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
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 HelloAspect {
    @Around("execution(* com.lzc.aop.controller.*.*(..))") // 这里是指controller包下所有类的所有方法
    public Object helloAspect(ProceedingJoinPoint jp) {
        try {
            ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            HttpServletRequest request = attributes.getRequest();
            System.out.println("拦截地址：" + request.getRequestURI());
            Object result = jp.proceed(); // 获取请求返回的结果
            return result;
        } catch (Throwable throwable) {
            throwable.printStackTrace();
            System.out.println("拦截出现异常：");
        }
        return null;
    }
}
