spring代码笔记

ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");

//BeanFactory 的子类
XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource("Beans.xml"));

//ApplicationContext接口，常用的接口实现FileSystemXmlApplicationContext，ClassPathXmlApplicationContext，WebXmlApplicationContext
ApplicationContext context = new FileSystemXmlApplicationContext("C:/Users/ZARA/workspace/HelloSpring/src/Beans.xml");

<bean id="..." class="..." init-method="..." scope="...">
</bean>

bean的作用域：singleton单例，prototype多例，request，session，global-session
bean的生命周期：bean的建立，Setter注入，BeanNameAware的setBeanName(),BeanFactoryAware的setBeanFactory(),BeanPostProcessors的processBeforeInitialization(),InitializingBean的afterPropertiesSet(),Bean定义文件中定义init-method,BeanPostProcessors的processAfterInitialization(),DisposableBean的destroy(),Bean定义文件中定义destroy-method
