我是做spring MVC的新手。 我能够创建一个 helloSpring 类型的应用程序，但这是基于注释的。 我删除了注释，因为我仍在学习 Spring MVC，所以我想首先学习 XML 配置方式，但由于某种原因，一旦我删除了注释部分，我的 jsp 就不会呈现。我想我已经正确设置了所有配置。奇怪的是，我的 JSP 修改出现时甚至没有呈现在页面上，所以我在地址栏上按下回车键以确认 Tomcat 是否没有呈现缓存设置并且它失败并显示 404。我使用 STS 作为我的 IDE。

刚才的Controller代码我也改成..
mv.setViewName("home");
mv.addObject("serverTime2", today);
谢谢 迪仁
最佳答案
似乎没有任何类型的错误，只是没有 Controller 和操作被映射到该 URL。根据您发布的内容，没有定义路由，因此 Spring MVC 不知道该怎么做。
我建议您打开日志记录以准确查看 spring 正在做什么，这将使您更好地了解管道中哪里出现故障。
我最近也学习了 spring，在 Spring MVC 3.0 中，注释是与 Controller 一起使用的方式，因为它比尝试在 XML 配置中正确连接所有内容更容易且更不容易出错。
如果您担心使用注解会将您的 Controller 耦合到 Spring，那么在实际 Controller 中还需要很多其他 Spring 组件，如果不付出大量努力，您将无法真正避免它。由于无论如何 Controller 都应该很薄，只需让您的 Controller (本质上是前端)绑定(bind)到 spring，然后您就可以根据需要保持后端解耦。
