解决：

将CronTriggerBean修改为CronTriggerFactoryBean。如：

 <bean id="CronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
         <property name="jobDetail" ref="myjob"/>
         <property name="cronExpression" value="0/2 * * * * ?"/>
     </bean>

注意：

由于Quartz 2.x修改了部分API，所以需要修改一下Quartz的配置。大体来说很简单，如下：

1）升级Spring的jar包

2）升级Quartz的jar包

3）修改配置

• 将CronTriggerBean修改为CronTriggerFactoryBean
• 将JobDetailBean修改为JobDetailFactoryBean
