在使用Spring3.0和Quartz2.0结合的时候出现的异常

异常信息：

<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE beans PUBLIC “-//SPRING//DTD BEAN//EN” “http://www.springframework.org/dtd/spring-beans.dtd“>
<beans>     
 <!–一： 调用工作的类 –>
 <bean id=”myjob” class=”com.wafer.springquartz.MyJob”>
 </bean>
 
 <!–二： 定义调用对象和调用对象的方法 –>
 <bean id=”jobinfo” class=”org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean”>
  <!– 1.调用的类 –>
  <property name=”targetObject”>
   <ref bean=”myjob”/>

  <!– 2.调用的方法 –>
  <property name=”targetMethod”>
   <value>helloword</value>

 <!–三:定义触发时间   org.springframework.scheduling.quartz.CronTriggerFactoryBean–>
 <bean id=”doTime” class=”org.springframework.scheduling.quartz.CronTriggerBean”>
  <property name=”jobDetail”>

  <!–四：总管理类 如果将lazy-init=’false’那么容器启动就会执行调度程序 –>
 <bean id=”StartQuertz” lazy-init=”false” autowire=”no” class=”org.springframework.scheduling.quartz.SchedulerFactoryBean”>
  <property name=”triggers”>
   <list>
    <ref bean=”doTime”/>
   </list>
  </property>
 </bean>
</beans> 

解决办法：

将doTime标签中的bean的class由：org.springframework.scheduling.quartz.CronTriggerBean

改为：  org.springframework.scheduling.quartz.CronTriggerFactoryBean即可

具体原因参见以下链接(本人解决办法也参照的如此链接知识版权属于原作者)：http://blog.csdn.net/shootyou/article/details/8175754

 

 

Caused by: java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class

 

原因是Spring 3.0版本中内置的Quartz版本是<2.0的，在使用最新的Quartz包(>2.0)之后，接口不兼容。

 

解决办法有两种：

1.降低Quartz版本，降到1.X去。

 

2.升级Spring版本到3.1+，根据Spring的建议，将原来的**TriggerBean替换成**TriggerFactoryBean，例如CronTriggerBean 就可以替换成 CronTriggerFactoryBean。替换之后问题解决。
