在DispatcherServlet中找不到带有URI [/]的HTTP请求的映射，其名称为“dispatcherServlet”但是多次

Question

我遇到了Spring MVC的奇怪问题。

当我在项目中打开根页面时，我看到：

WARNING: No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'dispatcherServlet'

没关系，因为我没有将任何内容映射到根...但问题是我连续3次收到此错误。

фев 27, 2015 12:41:44 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'dispatcherServlet'

фев 27, 2015 12:41:45 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'dispatcherServlet'

这是我的web.xml
