SpringBoot真正的入口是？

 

 真正的入口是鼠标指的类！！！！

org.springframework.web.SpringServletContainerInitializer

public void onStartup(@Nullable Set<Class<?>> webAppInitializerClasses, ServletContext servletContext) throws ServletException {
    List<WebApplicationInitializer> initializers = new LinkedList();
    Iterator var4;
    if(webAppInitializerClasses != null) {
        var4 = webAppInitializerClasses.iterator();

        while(var4.hasNext()) {
            Class<?> waiClass = (Class)var4.next();
            if(!waiClass.isInterface() && !Modifier.isAbstract(waiClass.getModifiers()) && WebApplicationInitializer.class.isAssignableFrom(waiClass)) {
                try {
                    initializers.add((WebApplicationInitializer)ReflectionUtils.accessibleConstructor(waiClass, new Class[0]).newInstance(new Object[0]));
                } catch (Throwable var7) {
                    throw new ServletException("Failed to instantiate WebApplicationInitializer class", var7);
                }
            }
        }
    }
