优雅REST风格的资源URL不希望带 .html 或 .do 等后缀.由于早期的Spring MVC不能很好地处理静态资源，所以在web.xml中配置DispatcherServlet的请求映射，往往使用 *.do 、 *.xhtml等方式。这就决定了请求URL必须是一个带后缀的URL，而无法采用真正的REST风格的URL。 如果将DispatcherServlet请求映射配置为"/"，则Spring MVC将捕获Web容器所有的请求，包括静态资源的请求，Spring MVC会将它们当成一个普通请求处理，因此找不到对应处理器将导致错误。 如何让Spring框架能够捕获所有URL的请求，同时又将静态资源的请求转由Web容器处理，是可将DispatcherServlet的请求映射配置为"/"的前提。由于REST是Spring3.0最重要的功能之一，所以Spring团队很看重静态资源处理这项任务，给出了堪称经典的两种解决方案。 先调整web.xml中的DispatcherServlet的配置，使其可以捕获所有的请求： <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load

That file is loaded automatically because it's called the same as a servlet. I want to thank everyone who tried to help me fix this issue. I'm keeping this question here, since it actually explains how to create a REST interface. It works perfectly. I'm trying to set up a RESTful interface with Spring-MVC. The server starts without issue, but any time I try to call the REST interface I get the message: 41 WARN [springframework.web

Can I use just glassfish-web.xml in my webapp and skip the others? 回答1: web.xml : Standard deployment descriptor defined by Java EE (Servlet JSR in particular, but used by many JSRs). It is used to specify the metadata used by the web container to deploy the application in a portable manner across application servers (such as the URL endpoint of a servlet). In Java EE 6 and beyond, it is optional (depending on technologies
