我正在使用 SpringSource 工具套件，我从模板创建了一个 Spring MVC 项目，我很难理解为什么当我在项目中单击“运行为...”时它工作正常，但是当我单击它时WEB-INF/views 目录中的 home.jsp 文件出现 404 错误，因此我也看不到其他 jsp。这是正常的行为吗？如果是这样，你能解释一下或指出我的解释吗？

这就是我在控制台中得到的。

一般来说，像 home.jsp 这样的静态文件是通过控制器渲染的。

在这种情况下，您的控制器是由注释驱动的，由

<annotation-driven />

位于 WEB-INF/spring/appServlet/servlet-context.xml 中的 XML 元素（假设您没有移动任何东西，我只是从模板中制作了一个示例 mvc 项目）

这意味着 Spring 会扫描您的 java 文件以查找 @Controller 对象，然后它将获取并绑定到视图。

home.jsp 不呈现的原因是因为它是通过位于您的基础包中的 HomeController 呈现的。

您应该注意到有一个带有以下签名的注释

@RequestMapping(value = "/", method = RequestMethod.GET)

这将您的应用程序的根上下文（无论项目名称是什么）绑定到此注释下方的方法，该方法应该是（即 localhost:8080/your_app/）

public String home(Locale locale, Model model)

您应该注意的是此控制器方法的 String 的返回类型。这表示方法完成后将呈现的视图名称。在这种情况下，它应该是：

return "home";

下一部分可能有点令人困惑，但过一段时间应该会有意义。“home”与 ViewResolver 相关联，如果你回到你的 servlet-context.xml，应该有一个带有类的 bean

org.springframework.web.servlet.view.InternalResourceViewResolver

注意正在设置的属性：

<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />

这意味着视图解析器将开始在 /WEB-INF/views/ 中查找“home”视图文件，并将 .jsp 附加到 home 的末尾。它找到的第一个匹配项将被返回，如果您查看目录结构，则其中有一个 jsp 文件：

/WEB-INF/views/home.jsp

希望这个回答对你有所帮助，欢迎评论。
