java - 使用默认模板的 spring mvc 中的 404 错误

Question

我是 SpringSource 的新手，我从模板创建了一个 Spring MVC 项目，除了在服务器home.jsp文件上运行之外我什么也没做但是我得到了404 error

我不知道该怎么做，因为我的控制台没有错误。我能做些什么？请帮我。

这是我在控制台中得到的内容 在此先感谢。

（我无法附上图片，因为我没有足够的声望点。）

Answer 1

你想访问http://localhost:8080/your-context-root/WEB-INF/views/home.jsp吗？

如果是这样，请尝试访问： http://localhost:8080/your-context-root/

您将看到“Hello world！”。

Answer 2

在 Eclipse 中创建默认 Spring MVC 项目时，我遇到了同样的问题。通常，当您看到 404 时，您收集的应用程序的根上下文路径存在问题。

在 Eclipse 中，您可以在 PROJECT_NAME/.settings/ org.eclipse.wst.common.component下的文件中找到该集合。

<property name="context-root" value="my_app"/>

因此http://localhost:8080/my_app会起作用。

还要检查/Servers/Tomcat v7.0 Server/ server.xml

<Context docBase="project_name " path="/my_app" reloadable="true" source="org.eclipse.jst.jee.server:eatin"/>
