Spring集成quartz框架实现定时任务(一)

1.添加pom.xml依赖

spring 依赖包

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context-support</artifactId>

<version>3.2.13.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-core</artifactId>

<version>3.2.13.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context</artifactId>

<version>3.2.13.RELEASE</version>

</dependency>

quartz依赖包

<dependency>

<groupId>org.quartz-scheduler</groupId>

<artifactId>quartz</artifactId>

<version>1.8.4</version>

</dependency>

2.接口设计

package ceilometer.timeTask;

import org.apache.log4j.Logger;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

import org.springframework.scheduling.quartz.QuartzJobBean;

public class NovaVmTask extends QuartzJobBean {

private static final Logger logger = Logger.getLogger(NovaVmTask.class);

/**

* Time Task：time update virtualhost！

*

* @param context

* job

* @throws JobExecutionException

* JobExecutionException

*/

@Override

protected void executeInternal(JobExecutionContext context)

throws JobExecutionException {

long start = System.currentTimeMillis();

try {

System.out.println("________________hello time world!!!!!!!!!!________________________");

} catch (Exception e) {

logger.error("PerforTask Error:", e);

}

}

}

3.applicationContext.xml配置定时任务,主要配置由定义调度工作任务,出发任务调节,启动定时任务组成

<!-- 1.定义调度工作任务 ,可以有好几种实现方式,这里只是其中有一种-->

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

<property name="jobClass">

<value>ceilometer.timeTask.NovaVmTask</value>

</property>

<property name="jobDataAsMap">

<map>

<entry key="novaVmService">

<ref bean="novaVmService" />

</entry>

</map>

</property>

</bean>

<!-- 2. 触发任务条件 -->

<bean id="novaVmTaskTrigger" lazy-init="false"

class="org.springframework.scheduling.quartz.CronTriggerBean">

<property name="jobDetail">

<!-- 要调用的业务 -->

<ref bean="novaVmTask" />

</property>

<property name="cronExpression">

<!-- 每5分钟触发一次 -->

<!-- <value>0 0/1 * * * ?</value> -->

<value>0 0/2 * * * ?</value>

</property>

</bean>

<!-- 3.启动定时器 -->

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"

autowire="no">

<property name="quartzProperties">

<props>

<prop key="org.quartz.scheduler.skipUpdateCheck">true</prop>

</props>

</property>

<property name="triggers">

<list>

<ref bean="novaVmTaskTrigger" />

</list>

</property>

</bean>

</beans>
