特别注意一点，与Spring整合必须使用Quartz1.8.x及以下版本，最初我拿2.1.3的，怎么搞都报错： 
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.scheduling.quartz.CronTriggerBean]
for bean with name 'mytrigger' defined in class path resource [applicationContext.xml]: problem with class file or dependent class; nested exception is java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.CronTriggerBean has
interface org.quartz.CronTrigger as super class 

查看发现spring3.0.5中org.springframework.scheduling.quartz.CronTriggerBean继承了org.quartz.CronTrigger（public class
CronTriggerBeanextends CronTrigger），而在quartz2.1.3中org.quartz.CronTrigger是个接口（publicabstract interface CronTrigger extends Trigger），而在quartz1.8.5及1.8.4中org.quartz.CronTrigger是个类（publicclass CronTrigger extends Trigger），从而造成无法在applicationContext中配置触发器。这是spring3和quartz2版本不兼容的一个bug。 

在Spring中使用Quartz有两种方式实现：第一种是任务类继承QuartzJobBean，第二种则是在配置文件里定义任务类和要执行的方法，类和方法仍然是普通类。很显然，第二种方式远比第一种方式来的灵活。 

第一种方式的JAVA代码： 

package com.ncs.hj;  

  

import org.quartz.JobExecutionContext;  

import org.quartz.JobExecutionException;  

import org.springframework.scheduling.quartz.QuartzJobBean;  

  

public class SpringQtz extends QuartzJobBean{  

    private static int counter = 0;  

    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {  

        System.out.println();  

        long ms = System.currentTimeMillis();  

        System.out.println("\t\t" + new Date(ms));  

        System.out.println(ms);  

        System.out.println("(" + counter++ + ")");  

        String s = (String) context.getMergedJobDataMap().get("service");  

        System.out.println(s);  

        System.out.println();  

    }  

}  

第二种方式的JAVA代码： 

package com.ncs.hj;  

  

import org.quartz.JobExecutionContext;  

import org.quartz.JobExecutionException;  

import org.springframework.scheduling.quartz.QuartzJobBean;  

  

import java.util.Date;  

  

public class SpringQtz {  

    private static int counter = 0;  

    protected void execute()  {  

        long ms = System.currentTimeMillis();  

        System.out.println("\t\t" + new Date(ms));  

        System.out.println("(" + counter++ + ")");  

    }  

}  

Spring的配置文件： 

<!------------ 配置调度程序quartz ，其中配置JobDetail有两种方式-------------->    

    <!--方式一：使用JobDetailBean，任务类必须实现Job接口 -->     

    <bean id="myjob" class="org.springframework.scheduling.quartz.JobDetailBean">    

     <property name="name" value="exampleJob"></property>    

     <property name="jobClass" value="com.ncs.hj.SpringQtz"></property>   

     <property name="jobDataAsMap">  

<map>  

    <entry key="service"><value>simple is the beat</value></entry>  

</map>  

;/property>  

    </bean>   

    <!--运行时请将方式一注释掉！ -->    

    <!-- 方式二：使用MethodInvokingJobDetailFactoryBean，任务类可以不实现Job接口，通过targetMethod指定调用方法-->    

    <!-- 定义目标bean和bean中的方法 -->  

    <bean id="SpringQtzJob" class="com.ncs.hj.SpringQtz"/>  

    <bean id="SpringQtzJobMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">  

    <property name="targetObject">  

        <ref bean="SpringQtzJob"/>  

    </property>  

    <property name="targetMethod">  <!-- 要执行的方法名称 -->  

        <value>execute</value>  

    </property>  

</bean>  

  

<!-- ======================== 调度触发器 ======================== -->  

<bean id="CronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">  

    <property name="jobDetail" ref="SpringQtzJobMethod"></property>  

    <property name="cronExpression" value="0/5 * * * * ?"></property>  

</bean>  

  

<!-- ======================== 调度工厂 ======================== -->  

<bean id="SpringJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  

    <property name="triggers">  

        <list>  

            <ref bean="CronTriggerBean"/>  

        </list>  

    </property>  

</bean>
