我在SpringMVC项目中遇到这个错误。我必须在浏览器中手动添加完整路径来运行代码，但我不能直接运行它。
org.springframework.web.servlet.DispatcherServlet noHandlerFound

请告诉我如何解决问题。
将springMVC-servlet.xml更改为大写S SpringMVC-servlet.xml
我认为您的应用程序上下文路径是“/”，而不是“SpringMVC”。您的请求uri不需要“/ SpringMVC”，例如“http://localhost:8080/student1”
更改你的应用程序pom.xml
<properties>
<springframework.version>4.0.6.RELEASE</springframework.version>
</properties>
