【问题描述】：
我目前正在设置一个使用休眠 bean 验证来验证登录页面上的表单字段的 Stuts2 应用程序。我添加了所有必要的插件和依赖项，并将 struts.xml 配置为包含一个调用 beanValidation 拦截器的自定义堆栈。 /logon 路径从 authInterceptor 中排除。不幸的是，即使填写了电子邮件和密码的表单字段，返回消息也是它们是空白的。我可以在调试器中看到在 LoginAction 类中设置了电子邮件和密码，但好像 beanValidation 没有此信息。如果我将拦截器的顺序切换到最后有 beanValidation，它永远不会被调用。

编辑 6/10/16
我更改了拦截器的执行顺序，以便 defaultStack 将首先执行，因为我的理解是它负责填充 ActionClass 中的 bean。现在，验证正在按应有的方式进行。但是，如果我将任何字段留空，则会返回正确的错误消息，但仍会调用 ActionClass 方法 doLogon。我现在正试图弄清楚如何让beanValidation 短路，以便不调用ActionClass。

问题是什么？有人可以发布正确答案吗？

问题就在最后。 “我现在正试图弄清楚如何让 beanValidation 短路，以便不调用 ActionClass。”
