推荐答案
正如其他人指出的那样，映射中没有getTutorial动作，只有"tutorial".但是，我将跳过这一点，建议您学习如何理智检查Struts2应用程序.每当您设置新技术时，甚至当您使用熟悉的技术时，了解如何进行基本的健全性检查也非常有用-在这种情况下，您需要验证struts xml是否已成功解析，并且框架知道您的操作.
As others have pointed out, you do not have a getTutorial action in your mapping, only a "tutorial". However, I'm going to skip over that and suggest that you learn how to sanity check a Struts2 app. Anytime you are setting up a new technology, and even when you are working with a familiar technology, it is very useful to understand how to do a basic sanity check -- in this case, you need to verify that your struts xml has been successfully parsed and the framework knows about your actions.
我强烈建议您添加 Struts 2 Config Browser插件到您的struts 2应用程序.要添加插件，您只需
I HIGHLY RECOMMEND you add the Struts 2 Config Browser plugin to your struts 2 apps. To add the plugin, you just get the jar ( all struts 2 plugins are jars ) and put in your webapp's lib directory. That's it. When you start your applicaiton, hit this URL:
http://localhost:8080/starter/config-browser/index.action
它向您显示了框架知道的所有动作以及其他配置. Essentialy struts 2诊断工具，太容易使用了，无法使用.
And it shows you all of the actions, as well as other configurations, that the framework knows about. Essentialy struts 2 diagnostic tool, and too easy to use to not use it.
