Spring MVC 3中关于url-pattern设成"/"后，资源访问问题

SpringMVC3中关于url-pattern设成"/"后，CSS等资源的访问会报错：No mapping found for HTTP request with URI。

解决办法是将资源类文件夹放到resources目录中，然后在 servlet-context.xml中 添加

xmlns:mvc="http://www.springframework.org/schema/mvc"

<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory --> <resources mapping="/resources/**" location="/resources/" />

运行服务输出：

INFO : org.springframework.web.servlet.handler.SimpleUrlHandlerMapping - Mapped URL path [/resources/**] onto handler 'org.springframework.web.servlet.resource.ResourceHttpRequestHandler#0'
