spring quartz配置定时器

首先建立bean.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
	<!--起动Bean-->
	<bean id="test"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="cronReportTrigger" />
			</list>
		</property>
	</bean>
	<!--实际的工作Bean-->
	<bean id="testjobbean"
		class="com.zhouxf.quartz.TestJobBean">
	</bean>
	<!--jobBean用于设定启动时运用的Bean与方法-->
	<bean id="scheduledReportJobDetail"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject">
			<ref bean="testjobbean" />
		</property>
		<property name="targetMethod">
			<value>run</value>
		</property>
	</bean>
	<!--定时器设定(0/2 43 12-17 * * ?在12-17点43分,每隔2秒运行一次)-->
	<bean id="cronReportTrigger"
		class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="scheduledReportJobDetail" />
		</property>
		<property name="cronExpression">
			<value>0/2 43 12-17 * * ?</value>
		</property>
	</bean>

</beans>



JOB代码:

public class TestJobBean{

    public void run() {
        System.out.println("run..................");
    }
}


测试代码:
 public static void main(String[] args) throws BeansException, FileNotFoundException, InterruptedException {
        // new LogInit("WEB-INF/classes/com/spring/helloworld/log4j.properties");
        BeanFactory factory = new XmlBeanFactory(
                                                 new FileSystemResource(
                                                                        "///home/zhouxf/work/WebPro/WebContent/WEB-INF/bean.xml"));
        factory.getBean("test");

    }



还有另一种配置方式,使用QuartzJobBean,它是JobDetailBean的子类,代码如下:
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class TestJobBean extends QuartzJobBean {

    @Override
    protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
        // TODO Auto-generated method stub
        System.out.println("TestJobBean..run................");
    }

}



配置文件中加入:
<bean id="reportJob" 
       class="org.springframework.scheduling.quartz.JobDetailBean"> 
    <property name="jobClass"> 
      <value>com.zhouxf.quartz.TestJobBean</value> 
    </property>  
  </bean> 
  
  	<!--定时器设定(0/2 43 12-17 * * ?在12-17点43分,每隔2秒运行一次)-->
	<bean id="cronReportTrigger2"
		class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="reportJob" />
		</property>
		<property name="cronExpression">
			<value>0/1 31 12-17 * * ?</value>
		</property>
	</bean>



测试代码改为:
public static void main(String[] args) throws BeansException, FileNotFoundException, InterruptedException {
        // new LogInit("WEB-INF/classes/com/spring/helloworld/log4j.properties");
        BeanFactory factory = new XmlBeanFactory(
                                                 new FileSystemResource(
                                                                        "///home/zhouxf/work/WebPro/WebContent/WEB-INF/bean.xml"));
        factory.getBean("test");
        factory.getBean("test2
    }




默认情况下,Quartz Jobs是无状态的,可能导致jobs之间互相的影响。如果你为相同的JobDetail指定两个Trigger, 很可能当第一个job完成之前,第二个job就开始了。如果JobDetail对象实现了Stateful接口,就不会发生这样的事情。 第二个job将不会在第一个job完成之前开始。为了使得jobs不并发运行,设置MethodInvokingJobDetailFactoryBean中的concurrent标记为false。

<bean id="scheduledReportJobDetail"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject">
			<ref bean="simpleJob" />
		</property>
		<property name="targetMethod">
			<value>run</value>
		</property>
		<property name="concurrent" value="false" />
</bean>

但是第二种方式的,没办法设置这个属性,暂时还不知道怎么去设置这个属性。
