package?QuartzTest;

import?java.util.Date;

public?class?CourseService?...{
???public?void?start()...{
???????System.out.println(new?Date().getSeconds());
???}
}
編寫調度類，需要繼承QuartzJobBean ： package?QuartzTest;

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


public?class?QuartzJob?extends?QuartzJobBean?...{????
????
????protected?void?executeInternal(JobExecutionContext?arg0)?throws?JobExecutionException?...{
????????courseService.start();
????}

????private?CourseService?courseService;

????public?CourseService?getCourseService()?...{
????????return?courseService;
????}

????public?void?setCourseService(CourseService?courseService)?...{
????????this.courseService?=?courseService;
????}
????

}
編寫配置文件 需要說明的是，我們有兩種trigger，分別是simple和cron模式，simple方式和timertask類似，采用設置interval方式進行調度，而cron可以特有的語法很詳細的定制調度執行時間，具體描述在配置文件的注釋中 <?xml?version="1.0"?encoding="UTF-8"?>
<!DOCTYPE?beans?PUBLIC?"-//SPRING//DTD?BEAN//EN"?"http://www.springframework.org/dtd/spring-beans.dtd"?>

?????????<ref?bean="cronReportTrigger"/>
???????</list>

???</bean>
</beans>

Spring還為我們提供了更簡單的加載調度的方式，也就說我們在已經有業務方法CourseService時不需要再額外編寫調度類QuartzJob,可以直接配置service的方法 <bean id="reportJbo" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
???? <property name="targetObject">
????? <ref bean="courseService"/>
???? </property>
???? <property name="targetMethod">
??????? <value>start</value>
???? </property>
?? </bean>
