我的基本Spring MVC Web应用程序不起作用。我创建了Simple Spring Web Maven项目并删除了不必要的代码来简化它。然后，我添加了Controller实现，并在我最近阅读的书中注释了它。我从book和我刚刚创建的应用程序部署了一个示例应用程序。示例应用程序正常工作 - 我没有。当我尝试访问URL ... localhost ... / app-name / start / basic / show Tomcat Server显示404错误。这是我的代码：
spring.app包中的BasicController
@Controller
@RequestMapping("/basic")
public class BasicController{
@RequestMapping("/show")
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
Map < String, String > modelData = new HashMap < String, String >();
modelData.put("message", "Hello World!");
return new ModelAndView("showMessage", modelData);
}
}

我试图解决这个问题，但所有内容都像示例应用程序一样实现，所以我不知道它为什么会失败。
我的痕迹，当我选择“在服务器上运行”并且我只部署了这个应用程序时：

好吧，假设我通过创建Spring MVC Project而不是Simple Spring Web Maven Project来解决这个问题。现在一切正常。
