Spring AOP在Bean生命周期中的调用时机

之前有写了一个生命周期的例子，直接拿来用，在每个生命周期方法中调用print方法。

加上AOP的代码

package com.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class AroundAspect {

	@Around("execution(* com.bean.MyMode.*(..))")
	public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
		String methodName = pjp.getSignature().getName();
		System.out.println("----Aspect before " + methodName + " called ");
		Object retVal = pjp.proceed();
		System.out.println("----Aspect after " + methodName + " called ");
		return retVal;
	}


}

运行得到结果：

InstantiationBeanPostProcessor postProcessBeforeInstantiation called

MyMode constructor call 1 MyMode constructor finish

InstantiationBeanPostProcessor postProcessAfterInstantiation called

InstantiationBeanPostProcessor postProcessPropertyValues called

BeanPostProcessor postProcessBeforeInitialization called 1 BeanPostProcessor postProcessBeforeInitialization finish

Mode @PostConstruct anno init called 1 MyMode @PostConstruct anno init finish

Mode afterPropertiesSet called 1 MyMode afterPropertiesSet finish

Mode @Bean anno Init called 1 MyMode @Bean anno Initfinish

BeanPostProcessor postProcessAfterInitialization called ----Aspect before print called 1 ----Aspect after print called BeanPostProcessor postProcessAfterInitialization finish

----Aspect before print called 1 ----Aspect after print called

Mode @PreDestroy anno destory called 1 MyMode @PostConstruct anno destory finish

Mode destroy called 1 MyMode destroy finish

Mode @Bean anno destory called 1 MyMode @Bean anno destory finish

结论是：在Bean的整个生命周期中，只有在初始化方法调用完之后销毁之前，AOP是有效的。
