嚴重: Dispatcher initialization failed java.lang.RuntimeException: java.lang.reflect.InvocationTargetException 問題解決

 

如果struts2版本是2.1以前

web.xml配置過濾器的時候應該是這樣：

<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>
</web-app>

 

如果struts2 版本是2.1以上

web.xml配置

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
  </filter>
  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>
