Google App Engine Appstats的java问题

Question

我在让Appstats正常工作方面遇到了问题。使用/appstats或/appstats/stats会在一个无限循环中结束，该循环会不断重定向回/appstats/stats。这会导致404错误，表示页面没有正确重定向。知道问题是什么吗

以下是我网站上的相关内容。xml。这与文档here基本相同

<servlet>
    <servlet-name>appstats</servlet-name>
    <servlet-class>com.google.appengine.tools.appstats.AppstatsServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>appstats</servlet-name>
    <url-pattern>/appstats/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>appstats</filter-name>
    <filter-class>com.google.appengine.tools.appstats.AppstatsFilter</filter-class>
    <init-param>
        <param-name>logMessage</param-name>
        <param-value>Appstats available: /appstats/details?time={ID}</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>appstats</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<security-constraint>
    <display-name>appstatsConstraint</display-name>
    <web-resource-collection>
        <web-resource-name>appstatsCollection</web-resource-name>
        <url-pattern>/appstats/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>admin</role-name>
    </auth-constraint>
</security-constraint>

以下是我的appengine网站上的相关内容。xml。我尝试过同时使用/appstats/stats和/appstats，但它们都有相同的问题

<admin-console>
    <page name="Appstats" url="/appstats/stats" />
</admin-console>

下面是显示无限重定向循环的http头：

Answer 1

谢谢你发布答案。在过去的一个小时里，我一直在搜索谷歌文档，试图找出哪里出了问题，然后在阅读你的帖子时，我意识到我有该死的URLRewite过滤器设置！干杯

Answer 2

事实证明，这是我的网站中的URL重写过滤器配置的问题。xml。我必须确保没有匹配的规则。我编辑了我的重写。下面是xml

<urlrewrite>
    <rule>
        <from>^(?!/appstats/)/(.*)$</from>
        <to last="true">/app/$1</to>
    </rule>
</urlrewrite>

/app/*是我的Spring dispatcher servlet映射
