java - Spring Controller 请求映射未被识别

Question

我从事一个业余项目已经有一段时间了，但我对 spring 框架仍然有些陌生。我注意到，当我在 tomcat 服务器上编译 Web 应用程序时，请求映射永远不会被识别。我已确保使用了组件扫描 xml 标记，但我不确定还可以在哪里查找它们未加载的原因。这是 github 项目的链接:

http://github.com/dmcquillan314/YouthMinistryHibernate.git

根据要求，这是我的 web.xml

<web-app id="WebApp_ID" version="2.4"

如果我需要进一步发布任何内容，请告诉我。

非常感谢任何帮助。提前致谢。

我无法检查您的项目是否存在本地问题，下面的链接解释了您可能使用的不同类型的配置标签，例如 mvc:annotation-drive 、context component-scan 等。

Different Spring Annotation XML Declarations

而且我还建议您将log4j添加到项目中，然后将日志级别设置为调试。这样当你启动项目时它可以打印出@RequestMapping中的所有url，当你向服务器发送请求时，它也可以打印出你发送的url，这样你就可以很容易地发现问题。
