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。见上一篇

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@Componentpublic 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。
