Question

我们正在将Web应用程序从struts 2.3.16升级到2.5.13。我们使用Web sphere应用程序服务器（WAS 8.5）来运行，IDE是RAD。

我添加了所有必需的JAR文件，但是我收到了此错误

Error 500: javax.servlet.ServletException: Filter [struts2]: Could not find required filter class - org.apache.struts2.dispatcher.FilterDispatcher.class

当我检查新的Struts-core-2.5.13时，它不包含org.apache.struts2.dispatcher.FilterDispatcher.class

我已在web.xml中更改过滤器，如下所示：

<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

Answer 1

过滤器org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter在Struts 2.5.x中不存在。

您应该使用org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter

有关详细信息，请参阅

Changed filter package in Struts >= 2.5
 As from Struts 2.5 all filters were moved to top package, see example:

 <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

在struts 2.5.13中找不到org.apache.struts2.dispatcher.filterdispatcher.class
