Quartz - JobSchedulingDataLoaderPlugin_jobInitializer'JobExecutionException'

我遇到了Quartz 1.8.4的問題。下面顯示'問題'（對Quartz沒有影響，除了混亂我的日誌文件）。Quartz - JobSchedulingDataLoaderPlugin_jobInitializer'JobExecutionException'

問：爲什麼拋出這個異常？

我在Tomcat 7.0.27運行此。

看來調度程序無法找到quartz_jobs.xml文件，因此無法爲此構建上下文。然而，你說從.xml作業正在執行，這讓人想知道如何。 Quartz本身或您的配置都有問題。因此，只需在最新版本的Quartz上運行它即可縮小範圍。 – Shinchan

你用scanInterval 10試過了嗎？它是否仍然有相同的警告？我的猜測是它無法獲得文件的鎖定 –

我調試了代碼，發現在調度程序上下文中找不到偵聽器名稱時會發生此異常。簡而言之，請查看您要調用的類文件是否存在於類路徑中，並且它們的路徑是否在屬性文件中正確設置。一個簡單的拼寫錯誤可能會導致此異常。一個簡單的方法是首先安排一個實例，看看它是否在沒有警告的情況下工作，然後添加另一個實例並查看警告等。

FileScanListener listener = (FileScanListener)schedCtxt.get(listenerName); 

    if(listener == null) { 
     throw new JobExecutionException("FileScanListener named '" + 
        listenerName + "' not found in SchedulerContext"); 
    }

希望它有幫助。
