初次尝试Quartz与Spring集成启动报错！

Question

本人菜鸟一枚 初次尝试Quartz与Spring集成

我这里尝试的是业务类继承QuartzJobBean的做法。Spring 3.2.4+Quartz2.2.1。

但是不幸的是启动的时候就报错了，唉。很蛋疼。报错找不到我的任务类。报错信息在下面有。

代码如下：

要调度的业务类：

package com.bdqn.service;

import java.util.Date;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class Services extends QuartzJobBean{
		@Override
		protected void executeInternal(JobExecutionContext arg0)
				throws JobExecutionException {
			// TODO Auto-generated method stub
			System.out.println("调用任务--"+new Date());
		}
}

applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</bean>
		
	 <!-- 定义触发时间 每隔2秒触发一次-->
	<bean id="CronTriggerFactoryBean" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
			<property name="jobDetail" ref="JobDetailFactoryBean"></property>
			<property name="cronExpression" value="0/2 * * * * ?"/>   
	</bean>
	
	<!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序  -->
	<!-- 如果lazy-init='true',则需要实例化该bean才能执行调度程序 -->
	<bean name="startQuertz" lazy-init="false" autowire="no"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="CronTriggerFactoryBean" />
			</list>
		</property>
	</bean>
</beans>

web.xml中也配置了。

报错信息：

Answer 1

嗯 你说的对。我改成ref不用value也是可以的！Tank You！

Answer 2

初看了一下

<property name="jobClass" value="Services"></property>

value应该是com.bdqn.service.Services吧，上面那个bean定义可以去了

你试试看，也不知道对不对
