如何将子文件夹用作web.xml的欢迎目录 [英] How to use a sub-folder as web.xml welcome directory
问题描述
我想为Google App Engine配置我的web.xml，但我的配置不起作用。我想用 WebApp / index.html 更改默认的 index.html 。
以下是 web.xml ：
< servlet的>
< servlet-name> App< / servlet-name>
< servlet-class> bg.app.AppServlet< / servlet-class>
< / servlet>
< servlet-mapping>
< servlet-name> App< / servlet-name>
< url-pattern> / WebApp / *< / url-pattern>
< / servlet-mapping>
< welcome-file-list>
< welcome-file> WebApp / index.html< / welcome-file>
< / welcome-file-list>
welcome file代表需要的物理文件通过URL请求文件夹时提供服务。例如。 / 或 / WebApp / 或 WebApp / foo / 。它并不代表许多首发者似乎认为的主页文件。让欢迎文件指向子文件夹是没有意义的。当另一个子文件夹被请求时，它会失败。
只要将 index.html 作为欢迎文件，在 / WebApp / 文件夹中创建所需的主页文件，并在根文件夹中创建另一个包含以下内容： index.html /
$ b
<！DOCTYPE html>
< html lang =en>
< head>
< title>虚拟主页< / title>
< meta http-equiv =refreshcontent =0; url = WebApp/>
< / head>
< / html>
这将重定向到 / WebApp / （搜索机器人会将它视为301），然后它将提供所需的主页文件。

I want to configure my web.xml for Google App Engine, but my configuration doesn't work. I want to change the default index.html with WebApp/index.html.
Here is the web.xml:
<servlet>
<servlet-name>App</servlet-name>
<servlet-class>bg.app.AppServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>App</servlet-name>
<url-pattern>/WebApp/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>WebApp/index.html</welcome-file>
</welcome-file-list>
The "welcome file" represents the physical file which needs to be served when a folder is requested by URL. E.g. / or /WebApp/ or WebApp/foo/. It does not represent the "homepage file" or so as many starters seem to think. It does not make sense to let the welcome file point to a subfolder. It would fail when another subfolder is been requested.
Just stick to index.html as welcome file, put the desired homepage file in /WebApp/ folder and create another index.html file in root folder / with the following content:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Dummy homepage</title>
<meta http-equiv="refresh" content="0; url=WebApp" />
</head>
</html>
This will redirect to /WebApp/ (searchbots will treat it as 301) which in turn should serve the desired homepage file.
