在配置了appfuse + Quartz 之後,本來測試的時候只是打印個測試語句而已,所以沒有發現該問題,當進行作業調度使用到相關的Manager的時候,才發現Quartz 是獨立的線程,無法獲取到appfuse裏的 ServletActionContext ,報出如下異常:
java.lang.NullPointerException

後經過請教高人,一下就解決了,解決方案可能有多種,我目前的解決方式是在項目裏構建一個ContextManager(假設就叫這個名字),然後在StartupListener中爲ContextManager設置當前的上下文對象,然後在Quartz啓動並使用Manager的時候,從ContextManager中獲取上下文.
