Question

我正在编写一个部署在Tomcat上的Spring MVC应用程序。我的应用程序的上下文名称是tranning。当我向http://localhost:8080/tranning/发送请求时，应用程序以HTTP状态404响应并记录以下内容：

＆＃34;警告：org.springframework.web.servlet.PageNotFound - 没有映射在DispatcherServlet中找到带有URI [/ tranning /]的HTTP请求 name＆＃39; appServlet＆＃39; ＆＃34;

的web.xml

    <?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

servlet的context.xml中

我在/WEB-INF/views/home.jsp上有一个JSP资源 enter image description here

认为你的网址存在问题。你在控制器类上使用了@RequestMapping("/tranning")注释吗？还使用了@Controller。

并将<mvc:annotation-driven>用于application-context.xml。

警告：org.springframework.web.servlet.PageNotFound - 在DispatcherServlet中找不到带有URI []的HTTP请求的映射，名称为＆＃39; appServlet＆＃39;
