Spring知识点

1、缓存规范JSR107

2、FactoryBean和BeanFactory

工厂 BeanFactory 

bean FactoryBean

应用

例如自己实现一个FactoryBean，功能：用来代理一个对象，对该对象的所有方法做一个拦截，在调用前后都输出一行LOG

3、ApplicationContextAware

 https://docs.spring.io/spring/docs/5.0.4.BUILD-SNAPSHOT/javadoc-api/org/springframework/context/ApplicationContextAware.html

4、InitializingBean

/**
 * Interface to be implemented by beans that need to react once all their
 * properties have been set by a BeanFactory: for example, to perform custom
 * initialization, or merely to check that all mandatory properties have been set.
 *
 * <p>An alternative to implementing InitializingBean is specifying a custom
 * init-method, for example in an XML bean definition.
 * For a list of all bean lifecycle methods, see the
 * {@link BeanFactory BeanFactory javadocs}.
 *
 * @author Rod Johnson
 * @see BeanNameAware
 * @see BeanFactoryAware
 * @see BeanFactory
 * @see org.springframework.beans.factory.support.RootBeanDefinition#getInitMethodName
 * @see org.springframework.context.ApplicationContextAware
 */
public interface InitializingBean {

	/**
	 * Invoked by a BeanFactory after it has set all bean properties supplied
	 * (and satisfied BeanFactoryAware and ApplicationContextAware).
	 * <p>This method allows the bean instance to perform initialization only
	 * possible when all bean properties have been set and to throw an
	 * exception in the event of misconfiguration.
	 * @throws Exception in the event of misconfiguration (such
	 * as failure to set an essential property) or if initialization fails.
	 */
	void afterPropertiesSet() throws Exception;
