解决：

将CronTriggerBean修改为CronTriggerFactoryBean。如：

[java] view
plaincopy





<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

Jobs added with no trigger must be durable

分类： quartz

quartz版本号：2.1.7

错误：Jobs added with no trigger must be durable

解决办法：

<property name="durability" value="true" />

durability 表示任务完成之后是否依然保留到数据库，默认false
