1.创建一个spring Boot 工程；spring-boot-quartz

2.引入关联包

    			
     
      org.springframework
     			
     
      spring-context-support
     			
     
      4.3.9.RELEASE
     		
    		
    			
     
      org.springframework
     			
     
      spring-tx
     			
     
      4.3.9.RELEASE
     		
    		
    			
     
      org.quartz-scheduler
     			
     
      quartz
     			
     
      2.2.3
     		
    		
    			
     
      org.quartz-scheduler
     			
     
      quartz-jobs
     			
     
      2.2.3
     		
    

3.创建Quartz配置类：QuartzConfiguare

/***quartz配置类*1.创建 SchedulerFactoryBean *2.创建 Scheduler */@Configuration //必须public class QuartzConfig {    @Bean    public SchedulerFactoryBean  schedulerFactoryBean(){        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();        return   schedulerFactoryBean;    }    @Bean    public Scheduler scheduler(){        return  schedulerFactoryBean().getScheduler();    }}

4.创建Job类;并实现Job接口

public class MyJob implements Job{    @Override    public void execute(JobExecutionContext context) throws JobExecutionException {        System.out.println("this is a Job "+new Date());    }}

5.创建任务类Task；包含：JobDetail、SimpleScheduleBuilder、Trigger、Scheduler

@Service // 通过spring事务来管理任务类，自动扫描实例化public class MyTask {    @Autowired    private Scheduler scheduler;    @PostConstruct // 相当于init-method    public void init(){        //jobDetail        JobDetail jobDetail = JobBuilder.newJob(MyJob.class).withIdentity("myJob","group1").build();//定义每两秒执行一次，执行到永远       SimpleScheduleBuilder simpleScheduleBuilder =SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2).repeatForever();        //trigger        Trigger trigger = TriggerBuilder.newTrigger().withIdentity("myTrigger","group2").startNow().withSchedule(simpleScheduleBuilder).build();        try {            scheduler.scheduleJob(jobDetail,trigger);        } catch (SchedulerException e) {            e.printStackTrace();        }    }}

6.最后执行SpringBoot运行类
