开始还以为是包冲突，到处找jar包。

搞不好久没有解决，后来无意间看了一下配置，（当时想知道，谁启动的它）就看了一下web.xml

  <filter>
    <filter-name>Struts2</filter-name>
    <filter-class>org.texturemedia.smarturls.SmartURLsFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>Struts2</filter-name>
    <url-pattern>*.jsp</url-pattern>
  </filter-mapping>
