Struts2 Bean验证

我目前正在设置一个Stuts2应用程序，该应用程序使用休眠bean验证来验证登录页面上的表单字段。我已经添加了所有必需的插件和依赖项，并将struts.xml配置为包括一个调用beanValidation拦截器的自定义堆栈。/ logon路径从authInterceptor中排除。不幸的是，即使填充了电子邮件和密码的表单字段，返回消息仍然是空白。我可以在调试器中看到已在LoginAction类中设置了电子邮件和密码，但是好像beanValidation没有此信息。如果我将拦截器的顺序切换到最后有beanValidation，则永远不会调用它。

我更改了拦截器的执行顺序，以便首先执行，defaultStack因为我的理解是它负责填充中的bean ActionClass。现在，验证正在按需进行。但是，如果我将任何字段保留为空白，则会返回正确的错误消息，但doLogon仍在调用ActionClass方法。我现在试图找出如何使beanValidation短路，以便ActionClass不被调用。
