我试图通过更改AdmissionForm.jsp 文件中h3 标记的内容来提供一些具有主题多重支持的主页，但在单击红色或绿色链接后我遇到了问题，我收到以下警告:
No mapping found for HTTP request with URI [/FirstSpringMVCProject/stylegreen.css] in DispatcherServlet with name 'spring-dispatcher'
or
No mapping found for HTTP request with URI [/FirstSpringMVCProject/stylered.css] in DispatcherServlet with name 'spring-dispatcher'

最佳答案
资源不应该存在于 WEB-INF 下，因为 servlet 容器绝不能直接从那里提供任何服务。由于您将调度程序 servlet 映射到 / 而不是 /*，因此 WEB-INF 之外的资源可以直接由 tomcat 提供服务。
只需将 css 文件直接在 WebContent 下移动一级即可。
关于java - 在 DispatcherServlet 中未找到名称为 'spring-dispatcher' 的 URI [/FirstSpringMVCProject/stylegreen.css] 的 HTTP 请求映射，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37974214/
