我仍然收到这个问题：警告：org.springframework.web.servlet.PageNotFound-在名为“appServlet”的DispatcherServlet中找不到URI为[/learning/avionSave]的HTTP请求的映射在我的avion.jsp页面中按AvionNew按钮后

该项目的工作原理如下：它将加载主页，在那里我将通过按avion按钮来重定向到avion.jsp页面。将出现名为AvionNew的新按钮。当我按下这个按钮时，我希望它加载@RequestMapping（value=“/avionSave”。。并仅打印到控制台System.out.println（“我们在这里吗？”）；但它不起作用，它仍然向我显示错误：(

我在谷歌上搜索了很多，看到了很多类似的话题，但我无法修复它：( 有人能帮我吗？

谢谢

您指向了错误的上下文路径。使用Tomcat，您可以在启动时在日志中看到类似的内容

OK - Deployed application at context path /foo

因此，您可以了解应用程序的上下文。

共享servlet-context.xml您是在根上下文下部署应用程序还是在tomcat中部署应用程序？请添加

根上下文.xml

和

servlet上下文.xml

文件我已经在主题中添加了根上下文和servlet上下文。如果我正在部署它？嗯，我正在本地主机上使用tomcat运行它
