WebApplicationInitializer是Spring提供用来配置Servlet 3.0+配置的接口，从而实现了替代web.xml的作用。

实现此接口将会自动被SpringServletContainerInitializer（用来启动Servlet3.0容器）获取到。

package com.lebron.springmvc;import javax.servlet.ServletContext;import javax.servlet.ServletException;import javax.servlet.ServletRegistration.Dynamic;import org.springframework.web.WebApplicationInitializer;import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;import org.springframework.web.servlet.DispatcherServlet;public class WebInitializer implements WebApplicationInitializer{@Overridepublic void onStartup(ServletContext servletContext) throws ServletException {AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();ctx.register(MyMvcConfig.class);   //加载springMVC配置ctx.setServletContext(servletContext);//注册springMVC的DispatcherServletDynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx)); servlet.addMapping("/");servlet.setLoadOnStartup(1);//servlet.setAsyncSupported(true);  //开启异步方法支持}}
