Spring Quartz集成Quartz初始化兩次

Question

我一直在努力將當前的項目與Jersey集成，該Web應用程序使用Spring進行IOC和Quartz調度。 但是在啟動配置后，我在啟動過程中在日志文件中注意到以下內容：

2014-08-15 05:43:10,830 INFO  org.quartz.core.SchedulerSignalerImpl.<init>:63 - Initialized Scheduler Signaller of type: class org.quartz.core.SchedulerSignalerImpl

2014-08-15 05:43:11,796 INFO  org.quartz.core.QuartzScheduler.start:461 - Scheduler org.springframework.scheduling.quartz.SchedulerFactoryBean#0_$_NON_CLUSTERED started.

是什么導致此初始化發生兩次？

Answer 1

導致調度程序運行兩次的最常見情況是，被調度的bean包含在多個上下文中。

確保調度的bean僅屬於根應用程序上下文。
