为什么我的 spring mvc 视图不会加载？

•浏览 1

Why won't my spring mvc views load?

我是 spring mvc 的新手。我目前正在使用 netbeans 8.0.2。以及一个spring mvc插件。从我在项目的 \\'libraries\\' 部分下看到的 jar 文件中，我似乎使用的是 spring mvc 4.0.1。

我可以从 tomcat 服务器甚至 glassfish 加载 index.jsp 页面，但如果我应该在目录结构 WEB-INFO>jsp>response.jsp 下创建另一个 .jsp 文件作为示例。我从服务器收到错误 404。这可能是一个可笑的简单修复，但到目前为止没有成功。

我怀疑这与我的控制器和 [springapp]-servlet.xml 文件有关。我在网上看到的大多数示例都使用 spring mvc 3.x 并避免在控制器设置中使用注释方法，乍一看后者对我来说似乎更容易。然后这些示例继续向上述 xml 文件添加几行。但是，我认为通过使用注释控制器设置，spring mvc 会自动检测我的控制器。不推荐使用注解方式吗？

我的配置文件如下：

如果有此问题的解决方案或更多信息

需要请告诉我。我也想解释任何答案

在我尝试学习时给出，而不仅仅是复制和粘贴解决方案。

这是我第一次尝试使用 java 创建 Web 应用程序，我必须说仅配置似乎相当令人生畏。

提前感谢您的时间和耐心。

好的，所以我找到的解决方案是将在 springapp-servlet.xml 中处理请求的控制器定义为 bean，并在控制器本身中重新定义该方法，以便它返回一个 ModelAndView (import org. springframework.web.servlet.ModelAndView；)。

我的页面现在呈现。

我应该注意到我已经重写了模型，但没有使用注释形式来编写控制器，但我很快也会以这种形式对其进行测试。现在我只是简单地实现了控制器接口。

感谢所有回复的人。感谢您的意见。

我认为在 web.xml 文件的欢迎文件列表中，您应该提供 Spring 控制器请求映射而不是 jsp 文件名，如下所示。
