Question

我遇到问题让Appstats正常工作。使用/ appstats或/ appstats / stats会在无限循环中结束，该循环会重定向回/ appstats / stats。这会导致404错误，表明页面未正确重定向。知道问题是什么吗？

以下是我的web.xml中的相关行。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-web.xml中的相关行。我尝试过使用/ appstats / stats和/ appstats，但他们都有同样的问题。

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

以下是显示无限重定向循环的http标头：

Answer 1

事实证明这是我在web.xml中使用的URL重写过滤器配置的问题。我必须确保没有匹配/appstats/*的规则。我将我的重写urlrewrite.xml编辑到下面。

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

/app/*是我的Spring调度程序servlet映射。

感谢您发布答案。我一直在寻找谷歌文档最后一个小时试图找出什么是错的，然后我意识到在阅读你的帖子，我有该死的urlrewrite过滤器设置！干杯！
