最近调试springboot的启动过程.看各种事件.
ServletWebServerApplicationContext.onRefresh
-->createWebServer()
-->this.webServer = factory.getWebServer(getSelfInitializer());
-->getSelfInitializer()
-->selfInitialize
ServletWebServerApplicationContext.selfInitialize
-->ServletWebServerApplicationContext.getServletContextInitializerBeans
-->ServletContextInitializerBeans.ServletContextInitializerBeans()
-->ServletContextInitializerBeans.addServletContextInitializerBeans
-->ServletContextInitializerBeans.getOrderedBeansOfType(ServletContextInitializer)
-->beanFactory.getBeanNamesForType(type-->ServletContextInitializer)
这个返回各种filter的名字.就是filter加载位置

// 这一段, md, 谁能看懂.
boolean matchFound =
(allowEagerInit || !isFactoryBean || (dbd != null && !mbd.isLazyInit()) || containsSingleton(beanName)) &&
(includeNonSingletons || (dbd != null ? mbd.isSingleton() : isSingleton(beanName))) && isTypeMatch(beanName, type);
if (!matchFound && isFactoryBean) {
// In case of FactoryBean, try to match FactoryBean instance itself next.
beanName = FACTORY_BEAN_PREFIX + beanName;
matchFound = (includeNonSingletons || mbd.isSingleton()) && isTypeMatch(beanName, type);
}
if (matchFound) {
result.add(beanName);
}
看不出有啥特征, servlet之类的.
