1.引入quzrtz
<dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.1</version> <exclusions> <exclusion> <artifactId>slf4j-api</artifactId> <groupId>org.slf4j</groupId> </exclusion> </exclusions> </dependency>
2.新建1个类,模拟定时任务
ScheduledJob.java
public class ScheduledJob implements Job{ @Override public void execute(JobExecutionContext context) throws JobExecutionException { System.out.println("第一个定时任务" + new Date()); } }
3.新建类MyScheduler
package com.abc.data.jobs; import org.quartz.*; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.scheduling.quartz.SchedulerFactoryBean; import org.springframework.stereotype.Component; @Component public class MyScheduler { @Autowired SchedulerFactoryBean schedulerFactoryBean; static Scheduler scheduler; public void scheduleJobs() throws SchedulerException { scheduler = schedulerFactoryBean.getScheduler(); startJob1(); } public static void startJob1() throws SchedulerException { JobDetail jobDetail = JobBuilder.newJob(DataSyncJob.class).withIdentity("job1", "group1").build(); CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/2 * * * * ?"); CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1") .withSchedule(scheduleBuilder).build(); scheduler.scheduleJob(jobDetail, cronTrigger); } }
3.添加SchedulerListener.java,必须有@Configuration注解
package com.abc.data.jobs; import org.quartz.SchedulerException; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.ApplicationListener; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.event.ContextRefreshedEvent; import org.springframework.scheduling.quartz.SchedulerFactoryBean; @Configuration public class SchedulerListener implements ApplicationListener<ContextRefreshedEvent> { @Autowired public MyScheduler myScheduler; @Override public void onApplicationEvent(ContextRefreshedEvent event) { try { myScheduler.scheduleJobs(); } catch (SchedulerException e) { e.printStackTrace(); } } @Bean public SchedulerFactoryBean schedulerFactoryBean() { SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean(); return schedulerFactoryBean; } }
5.启动springboot 即可看到效果 2秒/次
