IOC容器 bean生命周期

bean生命周期

GitHub code

<bean id="cycle1" class="club.cser.springroad.beans.BeanLifeCycle" init-method="initttt" destroy-method="destroyyyy">
    <property name = "cycle" value = "#{'spel city'}"/>
</bean>

1. constructt method...null

2. settingg method...spel city

3. initt method...spel city

4. BeanLifeCycle{cycle='spel city'} // 这个是 System.out.println(cycle1);

5. destroyy method...spel city //容器关闭时调用

BeanPostProcessor在init方法前后处理bean

实现 org.springframework.beans.factory.config.BeanPostProcessor

GitHub Code

1. constructt method...null

2. settingg method...spel city

3. postProcessBeforeInitialization: bean=BeanLifeCycle{cycle='spel city'} beanName=cycle1

4. initt method...spel city

5. postProcessAfterInitialization: bean=BeanLifeCycle{cycle='spel city'} beanName=cycle1

6. BeanLifeCycle{cycle='spel city'} // 这个是 System.out.println(cycle1);

7. destroyy method...spel city //容器关闭时调用
