• 新建DefaultConfigration.java

public class DefaultConfigration implements WebApplicationInitializer {

	@Override
	public void onStartup(ServletContext sct) throws ServletException {
		sct.setInitParameter("contextConfigLocation", "classpath:spring/spring-context.xml");
		
		XmlWebApplicationContext appContext = new XmlWebApplicationContext();
		appContext.setConfigLocation("classpath:springmvc/spring-mvc.xml");

		// spring监听器
		sct.addListener(ContextLoaderListener.class);

		// request监听器
		sct.addListener(RequestContextListener.class);

		// Introspector缓存清除监听器
		sct.addListener(IntrospectorCleanupListener.class);

		// 系统配置初始化监听
		sct.addListener(PaltfromListener.class);

		// 字符编码过滤器
		FilterRegistration.Dynamic encodingFilter = sct.addFilter("encodingFilter", CharacterEncodingFilter.class);
		encodingFilter.setInitParameter("encoding", "UTF-8");
		encodingFilter.setInitParameter("forceEncoding", "true");
		encodingFilter.addMappingForUrlPatterns(
				EnumSet.of(DispatcherType.REQUEST, DispatcherType.FORWARD, DispatcherType.INCLUDE), false, "/");

		ServletRegistration.Dynamic dispatcher = sct.addServlet("dispatcher", new DispatcherServlet(appContext));
		dispatcher.setLoadOnStartup(1);
		dispatcher.addMapping("/");

	
	
	}
}
之后按照你的web.xml 配置好上述文件，删除web.xml
