在 Quartz-Scheduler 中创建 bean 时出错

Question

我将quartz库从版本1.5.2更改为2.1.2。使用旧版本的项目可以正常运行，但使用 2.1.2 时出现异常：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'lcJobDetail' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.InstantiationError: org.quartz.JobDetail

applicationContext.xml 中的quartz 声明：

<bean name="lcTask" class="com.deveto.struts.triggers.TriggerLeagueCup"></bean>

<bean id="lcJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="lcTask" />
    <property name="targetMethod" value="execute" />
</bean>

<bean id="lcCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="lcJobDetail" />
    <property name="cronExpression" value="0 30 12 1/1 * ? *"/>
</bean>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
           <ref bean="lcCronTrigger"/>
        </list>
    </property>
</bean>

我找不到问题出在哪里，也许在你们的帮助下我会找到的。

Spring 3.1 版本中添加了 Quartz2 支持：

http://static .springsource.org/spring/docs/3.1.0.RC1/changelog.txt

将 Spring 依赖项更新到该版本（至少）或使用 Quartz 版本 1.8.x
