我面临一些奇怪的问题。执行一条规则（最后一条规则）是在转发之前将 url 放入时间，这给了我 404 错误。

web.xml 内容

    <filter>
  <filter-name>UrlRewriteFilter</filter-name>
  <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
  <init-param>
    <param-name>logLevel</param-name>
    <param-value>DEBUG</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>UrlRewriteFilter</filter-name>
  <url-pattern>/*</url-pattern>
  <dispatcher>REQUEST</dispatcher>
  <!-- FORWARD dispatcher will keep on parsing requests through rule until
     atleast one rule is applied . It sometime may lead into infinite loop
     --> 
  <!--    <dispatcher>FORWARD</dispatcher>  -->
</filter-mapping>

我的规则

<rule>
    <name>DepreatedUrls</name>
    <from>(/my/url2|/my/url3)</from>
    <set type="status">410</set>
    <to last="true">%{context-path}/error/410.html</to>
</rule>

<rule>
    <name>AllRemainingRequests</name>
    <note>
        This rule will block all other requests and return http error
        404 ( not supported ) and custom error message .
    </note>
    <from>(.*)</from>
    <set type="status">404</set>
    <to last="true">/error/410.html</to>
</rule>

所有其他规则都执行得很好。每条规则都是最后一条规则 (last="true")。但是当执行最后一条规则时，它会将请求转发到 /error/410.html/error/410.html

为了简单起见，我删除了大部分规则定义。以下是调试日志

经过一番尝试和尝试，我找到了解决方案。AllRemainingRequests 的“来自”组件令人不安。当我对 AllRemainingRequests 进行以下定义时，它可以正常工作。

<rule>
    <name>AllRemainingRequests</name>
    <from>(/.*)</from> 
    <set type="status">404</set>
    <to last="true">/error/410.html</to>
</rule>

唯一的变化是“/”
