struts2 - 在 struts.xml 文件（strust 2.3.4 框架）中使用“**constant**”时出现错误

Question

我正在尝试使用框架 strust2.3.4 运行项目，但是当我在 struts.xml 文件中使用“常量”时出现错误

<constant name="struts.convention.action.packages" value="com.pfs.pnn.action"/>

和配置动作

<action name="system_list" class="SystemListAction">
     <result name="success">/pages/system_list.jsp</result>
</action>

错误 ：

Caused by: Action class [SystemListAction] not found - action - file:/D:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/pnn/WEB-INF/classes/struts.xml:8:58

添加 struts2convention 插件，不提及完整包 <constant name="struts.convention.action.packages" value="action"/> 以获得更多链接https://cwiki.apache.org/confluence/display/WW/Convention%20Plugin
