SpringBoot实现AOP

引入pom

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
    <version>2.6.1</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.9.7</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.5.4</version>
</dependency>

　　新建AOP类

package com.geebox.wmstest.config;

import org.aspectj.lang.JoinPoint;
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.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;
import java.util.Arrays;

@Aspect
@Component
public class WebLogAcpect {
    private Logger logger = LoggerFactory.getLogger(WebLogAcpect.class);
    /**
     * 定义切入点
     */
    @Pointcut("execution(public * com.geebox.wmstest.controller..*.*(..))")
    public void webLog(){}

    /**
     * 前置通知：在连接点之前执行的通知
     * @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
        logger.info("URL : " + request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        logger.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
    }
    @AfterReturning(returning = "ret",pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求，返回内容
        logger.info("RESPONSE : " + ret);
    }
}

常见的切面表达式
1 所有公有方法的执行
execution(public * *(..))
2 所有以set开头的公有方法的执行
execution(* set*(..))
3 AccountService接口下的所有方法的执行
execution(* com.xyz.service.AccountService.*(..))
4 com.xyz.service包下的所有方法的执行
execution(* com.xyz.service.*.*(..))
5 com.xyz.service包及其子包下的所有方法的执行
execution(* com.xyz.service..*.*(..))
6 匹配com.xyz.service包下的所有类的所有方法（不含子包）
within(com.xyz.service.*)
7 com.xyz.service包和子包的所有方法
within(com.xyz.service..*)
8 匹配AccountService的代理类（不支持通配符）
this(com.xyz.service.AccountService)
