导读：我将石英库从版本1.5.2更改为2.1.2.使用它的旧版本,项目运行并且工作正常,但是在2.1.2中我得到了异常： Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'lcJobDetail' defined in class path resource

我将石英库从版本1.5.2更改为2.1.2.使用它的旧版本,项目运行并且工作正常,但是在2.1.2中我得到了异常：

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>

我无法找到问题所在,或许我会帮助你.

解决方法

Spring版本3.1中添加了Quartz2支持：

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

要么将Spring依赖项更新到该版本(至少),要么使用Quartz 1.8.x版
