springboot定义aop切面

1、创建springboot的demo项目

2、在pom.xml中引入依赖

<!--aop依赖-->

<dependency>
   <groupId>org.aspectj</groupId>
   <artifactId>aspectjrt</artifactId>
   <version>1.8.6</version>
</dependency>
<dependency>
   <groupId>org.aspectj</groupId>
   <artifactId>aspectjweaver</artifactId>
   <version>1.8.6</version>
</dependency>
<!--cglib依赖-->
<dependency>
   <groupId>cglib</groupId>
   <artifactId>cglib</artifactId>
   <version>3.1</version>
</dependency>
<!--slf4j依赖-->
<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-api</artifactId>
   <version>1.7.21</version>
</dependency>
<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-log4j12</artifactId>
   <version>1.7.21</version>
</dependency>

3、定义aop切面

package com.example.demo.controller;

import java.util.Arrays;
import javax.servlet.http.HttpServletRequest;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
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;

@Slf4j
@Aspect
@Component
public class OyoLogAcpect {
   
   /**
    * 定义切入点
    */
   @Pointcut("execution(public * com.example.demo..*.*(..))")
   public void webLog(){}

   /**
    * 动态代理在执行方法前记录日志
    * @param joinPoint
    * @throws Throwable
    */
   @Before("webLog()")
   public void doBefore(JoinPoint joinPoint) throws Throwable {
       // 接收到请求，记录请求内容
       ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
       HttpServletRequest request = attributes.getRequest();

       // 记录下请求内容
       log.info("URL : " + request.getRequestURL().toString());
       log.info("HTTP_METHOD : " + request.getMethod());
       log.info("IP : " + request.getRemoteAddr());
       log.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
       log.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
   }

}

4、写一个hello程序

5、测试

运行并访问

6、查看控制台

7、so easy！😚
