首先编写服务类:
package QuartzTest;
import java.util.Date;
public class CourseService {
public void start(){
System.out.println(new Date().getSeconds());
}
}
编写调度类,需要继承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;
}
}
编写配置文件
需要说明的是,我们有两种trigger,分别是simple和cron模式,simple方式和timertask类似,采用设置interval方式进行调度,而cron可以特有的语法很详细的定制调度执行时间,具体描述在配置文件的注释中
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >
<beans>
<bean id="courseService" class="QuartzTest.CourseService"/>
<!-- 创建调度任务 使用单独编写的调度类QuartzJob -->
<bean id="reportJbo" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass">
<value>QuartzTest.QuartzJob</value>
</property>
<property name="jobDataAsMap">
<map>
<!--采用jobDataAsMap方式进行courseService注入-->
<entry key="courseService">

</entry>
</map>
</property>
</bean>
<!-- 创建调度任务 使用已有的service类方法,不需要单独编写调度类QuartzJob
<bean id="reportJbo" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject">
<ref bean="courseService"/>
</property>
<property name="targetMethod">
<value>start</value>
</property>
</bean>
-->
<!-- 配置调度任务,简单模式 -->
<bean id="simpleReportTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail">
<ref bean="reportJbo"/>
</property>
<property name="repeatInterval">
<value>1000</value>
</property>
</bean>
<!-- 配置调度任务,复杂定制模式,月份中的日期和星期不能同时设置 -->
<bean id="cronReportTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="reportJbo"/>
</property>
<property name="cronExpression">
<value>02 20 21 7 6 ? 2007</value>
<!-- 1.秒 0-59
2.分钟 0-59
3.小时 0-23
4.月份中的日期 1-31
5.月份 1-12或者Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov Dec
6.星期中的日期 1-7或者MON,TUE,WED,THU,FRI,SAT,SUN.
-->
</property>
</bean>
<!-- 启动调度 -->
<bean id="start" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronReportTrigger"/>
</list>
</property>
</bean>
</beans>
Spring还为我们提供了更简单的加载调度的方式,也就说我们在已经有业务方法CourseService时不需要再额外编写调度类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>
