Question

我正在开发基于Java和JSF2.0的Web应用程序，我正在使用Google AppEngine来托管它。我正在使用PrettyFaces来修改URL。自从我开始使用PrettyFaces以来，如果有人输入了无效的URL，则会发生重定向循环，如下所示：

www.example.com

是网站所以，如果你输入

www.example.com/invalidasdas

它会一直将index.jsp附加到无效URL的末尾，例如：

www.example.com/invalidasdas/index.jsp/index.jsp/index.jsp/index.jsp/index.jsp

我不确定如何解决这个问题。任何解决这个问题的建议都会很好。如果需要，我可以发布我的代码。

PrettyFaces配置：

    <pretty-config xmlns="http://ocpsoft.org/schema/rewrite-config-prettyfaces" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://ocpsoft.org/schema/rewrite-config-prettyfaces
                      http://ocpsoft.org/xml/ns/prettyfaces/rewrite-config-prettyfaces.xsd">

    <url-mapping id="home">
        <pattern value="/home/" />
        <view-id value="/index.jsf" />
    </url-mapping>
    <url-mapping id="blog">
        <pattern value="/blog/" />
        <view-id value="/blog.jsf" />
    </url-mapping>
    <url-mapping id="stockpicks">
        <pattern value="/stocks/" />
        <view-id value="/stockpicks.jsf" />
    </url-mapping>
    <url-mapping id="login">
        <pattern value="/login/" />
        <view-id value="/adminlogin.jsf" />
    </url-mapping>
    <url-mapping id="dashboard">
        <pattern value="/dashboard/" />
        <view-id value="/dashboard.jsf" />
    </url-mapping>
    <url-mapping id="error">
        <pattern value="/error/" />
        <view-id value="/WEB-INF/error.jsf" />
    </url-mapping>
    <url-mapping id="search">
        <pattern value="/search/#{searchBean.type}/#{searchBean.value}"></pattern>
        <view-id value="/search.jsf"/>
    </url-mapping>

</pretty-config>

这是我的web.xml文件！

编辑：事实证明问题是AppEngine而不是PrettyFaces。请不要在没有真正调查问题的情况下停止编辑帖子有人删除了AppEngine标签，这很烦人！

我遇到了与你相同的问题，但是当我添加＆＃34; / WEB-INF＆＃34;查看id值它的工作原理！即：

    ...
    <url-mapping id="home">
            <pattern value="/home/" />
            <view-id value="/WEB-INF/index.jsf" />
    </url-mapping>
    ...

它有效，但我不相信这个解决方案，我正在尝试调查它
