篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了quartz 定时任务调度管理器相关的知识，希望对你有一定的参考价值。
本项目使用的是spring-quartz
以下配置可以开启多个已知定时任务
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:task="http://www.springframework.org/schema/task" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 6 http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> 7 8 9 <!--<util:properties id="quartz" location="classpath:quartz.properties" />--> 10 11 <!-- single thread --> 12 <task:executor id="threadPoolTaskExecutor" pool-size="1"/> 13 14 <!-- Scheduler factory bean to glue together jobDetails and triggers to Configure Quartz Scheduler --> 15 <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 16 <property name="jobFactory"> 17 <bean class="com.xxx.servicenode.pushtaskserver.quartz.task.MySpringBeanJobFactory"/> 18 </property> 19 <property name="startupDelay" value="0"/> 20 <property name="taskExecutor" ref="threadPoolTaskExecutor"/> 21 <property name="triggers"> 22 <list> 23 <ref bean="cronTrigger"/> 24 </list> 25 </property> 26 </bean> 27 28 <!-- Run the job every 5 seconds --> 29 <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> 30 <property name="jobDetail" ref="myjobDetail"/> 31 <!--<property name="cronExpression" value="0/5 * * ? * SAT-SUN" />--> 32 <property name="cronExpression" value="#{config[‘quartz.time‘]}"/> 33 </bean> 34 <bean id="myjobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean"> 35 <property name="jobClass" value="com.xxx.servicenode.pushtaskserver.quartz.task.MyJob"/> 36 </bean> 37 38 </beans>
MySpringBeanJobFactory:
1 public class MySpringBeanJobFactory extends SpringBeanJobFactory { 2 3 @Autowired 4 private AutowireCapableBeanFactory autowireCapableBeanFactory; 5 6 @Override 7 protected Object createJobInstance(TriggerFiredBundle bundle)throws Exception { 8 Object jobInstance = super.createJobInstance(bundle); 9 autowireCapableBeanFactory.autowireBean(jobInstance); 10 return jobInstance; 11 } 12 }
MyJob:
1 public class MyJob extends QuartzJobBean { 2 3 private final static Logger logger = LoggerFactory.getLogger(MyJob.class); 4 5 @Override 6 protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException { 7 //处理自己的业务逻辑 8 } 9 }

经测试：定时任务调度器开启的定时任务，当任务状态为：完成（COMPLETE）时，此任务自动回收
