我的web.xml是这样的:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

在这个论坛上阅读后我尝试了很多东西:

  1. 尝试了不同版本的JAR。
  2. 将WAR手动部署到Tomcat中。
  3. 也将servlet-api JAR放入lib文件夹中(尽管它存在于服务器lib中)。
  4. 阅读Tomcat日志,发现没什么不同。 (请告诉我,我也可以粘贴)
  5. 但他们都没有帮助。所以,不得已,我在这里发帖。

因为您使用的是Struts 2.3,

不推荐使用FilterDispatcher 。你必须使用StrutsPrepareAndExecuteFilter(或它的小兄弟)。

From the official documentation

  

<强>已过时即可。 自Struts 2.1.3起,使用 StrutsPrepareAndExecuteFilter StrutsPrepareFilter StrutsExecuteFilter ,如果需要使用ActionContextCleanUp过滤器

然后改变这个

<!-- Struts < 2.1.3 -->
<filter-class>
    org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>

到此:

<!-- Struts >= 2.1.3 and < 2.5 -->
<filter-class>
     org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>

请注意,从2.5开始,它将改为:

<!-- Struts >= 2.5 -->
<filter-class>
     org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
</filter-class>
