当存在数据时，jquery 网格在 struts2 中产生 "Could not find action or result"

Question

我有工作项目，但在升级 java、tomcat 和少数库后，内部 jquery-grid 之一停止工作。（是的，外部 "jsonPatientAppointments" 仍在工作）如果在这种情况下没有数据，它不会抛出任何错误，但如果在这种情况下存在数据 struts2 操作将抛出 "Could not find action or result"。

我的行动class是

   @ParentPackage(value = "patient")
 public class JsonAppointmentHistoryAction extends ActionSupport implements 
 SessionAware

根据

no result defined for action and result exception

我认为您的执行方法抛出一些异常。我可以推荐 Struts Global Exception Handling 看看会发生什么。

当存在数据时，jquery 网格在 struts2 中产生 "Could not find action or result"

jquery grid results in "Could not find action or result" in struts2 when data is present
