用於WebApplicationInitializers類的等效web.xml？

Question

什麼是WebApplicationInitializers類的web.xml的等價物？

package com.concretepage.config; 
    import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; 
    public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 
     @Override 
     protected Class<?>[] getRootConfigClasses() { 
      return new Class[] { AppConfig.class }; 
     } 
     @Override 
     protected Class<?>[] getServletConfigClasses() { 
      return null; 
     } 
     @Override 
     protected String[] getServletMappings() { 
      return new String[] { "/" }; 
     } 
    } 

Answer 1

看一看WebApplicationInitializer的API文檔 http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/WebApplicationInitializer.html

Answer 2

由於AppConfig的在rootConfig，應當通過的ContextLoaderListener
