Tomcat URLRewriteFilter规则附加到url 2次

我面临着一些奇怪的问题。执行一条规则（最后一条规则）是在转发之前将url设置为times，这会给我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>

经过反复试验，我找到了解决办法。 所有剩余请求的“from”组件都很麻烦。 当我为AllRemainingRequests下以下定义时，它工作得很好

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

所有剩余请求
(/.*) 
404
/错误/410.html

唯一的变化是“/”
