spring集成quartz
|
|
|
|
注意：出现异常“Caused by: java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class”
|
|
|
|
Spring3.0不支持Quartz2.0,因为org.quartz.CronTrigger在2.0从class变成了一个interface造成IncompatibleClassChangeError错误:
|
|
|
|
|
|
|
|
有两种办法：
|
|
|
|
第一种降低quartz的版本为，最好是quartz1.8
|
|
|
|
第二种是升级spring版本为Spring3.2以上
|
|
|
|
注：Spring3.2.4配置文件中使用CronTriggerFactoryBean来集成quartz2.x,
|
|
|
|
使用CronTriggerBean来集成quartz1.8.x及以前版本.
|
|
|
|
|
|
|
|
以下是一个小例子demo
|
|
|
|
<!-- 启动触发器的配置开始 -->
|
|
|
|
<bean name="startQuertz" lazy-init="false" autowire="no"
|
|
|
|
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
|
|
|
|
<property name="triggers">
|
|
|
|
<list>
|
|
|
|
<ref bean="myJobTrigger" />
|
|
|
|
</list>
|
|
|
|
</property>
|
|
|
|
</bean>
|
|
|
|
<!-- 启动触发器的配置结束 -->
|
|
|

|
|
|
|
<!-- 调度的配置开始 -->
|
|
|
|
<!--
