存在數據時，jquery網格在struts2中導致“找不到動作或結果”

Question

我當時正在工作的項目，但是在升級java，tomcat和一些庫之后，內部jquery-grid之一停止工作。 （是的，外部的一個“ jsonPatientAppointments”仍在工作）如果在這種情況下沒有數據，則不會引發任何錯誤，但是如果在這種情況下存在數據，則struts2操作將引發“找不到操作或結果”。

我的動作課是

   @ParentPackage(value = "patient")

 SessionAware

根據

沒有為操作和結果異常定義結果

我認為您的execute方法會引發一些異常。 我可以推薦Struts全局異常處理以了解會發生什么。
