用spring 3+quartz 2,然后照着网上的demo做的时候,可能你会遇到
class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class
这样的问题 ,就是说spring里的CronTriggerBean类继承的居然是quartz中的一个接口,CronTrigger在quartz 2的版本中是一个接口。而在quartz 1中它是个类。所以,一种方法是降低quartz 版本可以解决这个问题。
另一种方法是使用另一个spring提供的CronTriggerFactoryBean。具体可看这里。
