【學習筆記】Spring-3.2.4 + Quartz-2.2.0集成實例

Spring3.0不支持Quartz2.0,因爲org.quartz.CronTrigger在2.0從class變成了一個interface造成IncompatibleClassChangeError錯誤:
Caused by: java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class

今天剛下載了Spring3.2.4,發現這個新版本已經支持quartz2.x了.以前的Spring版本只支持Quartz-1.8.x及以前的版本,做個小實例分享一下.

注：Spring3.2.4配置文件中使用CronTriggerFactoryBean來集成quartz2.x,使用CronTriggerBean來集成quartz1.8.x及以前版本.

代碼結構及引用jar見下圖:
