推荐答案
如果你有...
- 包括所有必要的罐子
- 正确配置构建路径
- 将它们全部添加到部署程序集中
正确.
那么你也会收到java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher"错误，那么你可能做错了以下事情.
then also you getting "java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher" error then you could be doing below things wrong.
解决方案:
检查您的 struts2-core-x.x.jar 版本.
-->如果它是 struts2-core-2.5.jar 然后将 web.xml 中的过滤器类标记值更改为
-->if it is struts2-core-2.5.jar then change your filter class tag value in web.xml to
<filter-class>
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
</filter-class>
-->如果它是 struts2-core-2.1.3.jar 然后将 web.xml 中的过滤器类标记值更改为
-->if it is struts2-core-2.1.3.jar then change your filter class tag value in web.xml to
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
FilterDispatcher 从 Struts 2.1.3 开始被弃用.如果您使用的是旧版本，请使用上述解决方案.
FilterDispatcher is deprecated since Struts 2.1.3. If you are working with older versions then user above solution.
-->如果是 struts2-core-2.3.X.jar 然后将 web.xml 中的过滤器类标记值更改为
-->if it is struts2-core-2.3.X.jar then change your filter class tag value in web.xml to
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
这一切背后的原因是 struts 2 控制器被放置在不同版本的 struts2-core jar 中的不同位置，并且有时它们被称为不同的名称，如您在 2.1.3 中所见.
Reason behind all this is struts 2 controllers are placed in different location in different version of struts2-core jar and some time they are called by different name as you can see in 2.1.3.
