Spring 新手：我的 DispatcherServlet 的 url 模式似乎“覆盖”了欢迎文件

Question

我使用 Spring 来呈现 JSP，并且我的 DispatcherServlet 的 url 模式是“/”。这似乎使得欢迎文件列表永远不会被考虑。我实际上希望 DispatcherServlet 能够处理除“/”之外的所有内容。但是，我想避免使用文件扩展名（例如 *.html、.do 等），并且我使用 InternalResourceViewResolver，因此为调度程序 servlet 设置 url 模式到“/”使其接受太多（例如，InternalResourceViewResolver 生成的 JSP 页面的内部请求将被调度程序 servlet 拦截，然后抛出一个错误，因为它没有 /WEB-INF/jsp/about.jsp 的映射）。任何帮助将不胜感激 - 我对 Spring 非常 很陌生（例如 2 天;-) ）

以下是适当的文件：

目录结构

/war (I'm using AppEngine)
  index.jsp (Simply includes WEB-INF/jsp/index.jsp)
  /WEB-INF
    XML Config files

    /jsp
      index.jsp
      about.jsp
      ...

    We purposefully do not make this /*. The convention here is to define
    mappings for files that exist, and write a good 404 page for anything
    else. Also, if you say /*, then the dispatcher servlet will intercept
    all requests, and the InternalResourceViewResolver will fail to
    resolve internal resources (e.g. jsp pages) because the dispatcher
    servlet will be intercepting all of the requests, even the internal
    ones

<!--
    Given an arbitrary view name, such as 'about, that has been returned
    from a handler (controller), this will simply create
    '/WEB-INF/jsp/about.jsp' and send that to the Dispatcher Servlet.
    Because of the way ViewResolvers are chained (e.g. search until a View
    is found), coupled with the annoyance that this ViewResolver cannot
    determine if a View is found, this *has* to be the last ViewResolver
    considered, so I have set the order very high. See
    http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-viewresolver-chaining

JSP 控制器（控制器之一）包含在 org.foo.server.controllers 包中）

@Controller
public class WebportalController {
@RequestMapping(value = "/myforms", method = RequestMethod.GET)
public String getMyForms() {
    return "myforms";
}

@RequestMapping(value = "/about", method = RequestMethod.GET)
public String getAbout() {
    return "about";
}
... etc (for now all of the JSP pages are fairly static)
}

Answer 1

我解决这个问题的方法是给 dipatcher servlet 一些前缀，并将带有该前缀的所有内容转发给它（包括扩展）。就我而言，我使用了 webapp，然后还有其他一级目录，例如 images 等。这是我发现的唯一方法（除了 URL 重写）让这个发挥作用。此外，如果您愿意，您可以使用 URL 重写引擎从没有扩展名的请求中删除 webapp 等。
