集群环境下控制定时钟执行的一种方法

Java：
public class SignleTaskStart implements InitializingBean { private ResourceLoaderService resourceLoaderService; private Scheduler signleTaskStart; private CronTriggerBean payPointRetryTrigger; public void init() throws SchedulerException { if (!readStartFlag()) { return; } try { signleTaskStart.scheduleJob(payPointRetryTrigger.getJobDetail(), payPointRetryTrigger); } catch (SchedulerException e) { logger.error("SignleTaskStart.execute", e); throw e; } logger.info("add pay point service success"); } public boolean readStartFlag() { File f = null; boolean canRun = false; try { f = resourceLoaderService.getResourceAsFile("/singleRunFlag/taskrunflag", ResourceOption.NEED_NOT_EXIST); if (f != null && f.exists()) { canRun = true; FileUtils.touch(f); } } catch (ResourceNotFoundException e) { logger.info("pointRecoverFlag file not exist"); } catch (IOException e) { logger.error("touch file fail", e); } return canRun; } }

spring-config:

<bean class="com.test.task.point.SignleTaskStart" init-method="init"/> <bean id="signleTaskStart" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="waitForJobsToCompleteOnShutdown" value="true" /> <property name="autoStartup"><value>true</value></property> </bean>
