qqyycom / AbstractAnnotationConfigDispatcherServletInitializer

Last active December 22, 2020 10:26

springMVC中servletContext的初始化过程

	// Initializer结构中最顶层的抽象类，可以直接拓展它，使用了模板方法的设计模式，每个子类都专注一个功能
	public abstract class AbstractAnnotationConfigDispatcherServletInitializer
	extends AbstractDispatcherServletInitializer {

	// 如果实现类没重写createRootApplicationContext()方法, 则在创建RootApplicationContext会被调用
	@Override
	@Nullable
	protected WebApplicationContext createRootApplicationContext() {
	//指定rootWebApplicationContext的configClasses类，可以有多个,也可以没有; 如果有,getRootConfigClasses()需要被重写
	Class<?>[] configClasses = getRootConfigClasses();

springBean的生命周期

	public abstract class AbstractApplicationContext extends DefaultResourceLoader
	implements ConfigurableApplicationContext {
	//每次refresh会destory Beanfactory中已经初始化的对象
	public void refresh() throws BeansException, IllegalStateException {
	synchronized (this.startupShutdownMonitor) {

	prepareRefresh();

	// ,刷新beanFactory(如果没有,就创建一个)从配置文件或配置类中读取beanName,beanDefinition等信息,并注册到beanFactory中
	ConfigurableListableBeanFactory beanFactory = obtainFreshBeanFactory();
