SpringBootでAOP

Dependencies Version

Library	Version
org.springframework.boot:spring-boot-starter-aop	2.4.0

実装例

aop.java

package com.example.aop;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class MethodStartEndAspect {

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

    @Before("execution(* com.example..*(..))")
    public void start(JoinPoint joinPoint) {
        logger.info("START {}#{}", joinPoint.getSignature().getDeclaringType().getName(), joinPoint.getSignature().getName());
    }

    @After("execution(* com.example..*(..))")
    public void end(JoinPoint joinPoint) {
        logger.info("END {}#{}", joinPoint.getSignature().getDeclaringType().getName(), joinPoint.getSignature().getName());
    }

}

@EnableAspectJAutoProxyは不要。

Spring Bootに内包されているので。
