Java guice-struts2-plugin-2.0支持struts2.x吗？

我正在我的应用程序中使用Guice 2.0及其struts插件“Guice-struts2-plugin-2.0”。struts版本是'Struts2-core-2.1.8.1，应用服务器是JBoss4.2.2。 部署应用程序时遇到问题

google guice真的支持Struts2集成吗？？？guice-struts2-plugin-2.0是struts的成熟插件吗

---

请提供任何帮助。

该页面是将guice与struts 2.2及更高版本结合使用的示例。看起来您正在使用struts 2.1.8.1，因此该示例对您不起作用。我也遇到了同样的问题，但是通过使用上的示例，我能够将guice与struts<2.2一起使用。还有一点工作量，但确实有效。

感谢kodova的回复。我很久以前就解决了这个问题。struts 2.1.8.1可以正常工作，我忘了添加guice-servlet-2.0.jar.guice-struts2-plugin-2.0.jar来处理guice2.0。
