spring boot integrates quartz to achieve multiple timed tasks

Recently, I have received a lot of emails, all wanting to know how spring boot integrates quartz to achieve multiple timing tasks. Since I did not use multiple timing tasks in production, here is the idea of implementation.

1. Create two new timed tasks, as follows:

public class ScheduledJob implements Job{  
  @Override 
  public void execute(JobExecutionContext context) throws JobExecutionException {  
    System.out.println("schedule job1 is running .....................................................................  ");  
  } 
} 
public class ScheduledJob2 implements Job { 
 
  @Override 
  public void execute(JobExecutionContext context) throws JobExecutionException {  
    System.out.println("schedule job2 is running  ......................................................................................................... ");  
  } 
} 

2. Configure the above two tasks

@Component 
public class SchedulerAllJob { 
  @Autowired 
  private SchedulerFactoryBean schedulerFactoryBean;    
  /* 
   *  Here you can inject database operations to query all task configurations  
   */    
  /** 
   *  This method is used to start all timing tasks  
   * @throws SchedulerException 
   */ 
  public void scheduleJobs() throws SchedulerException { 
    Scheduler scheduler = schedulerFactoryBean.getScheduler();      
    /** 
     *  
     */ 
    scheduleJob1(scheduler);  
    scheduleJob2(scheduler);  
  } 
   
  /** 
   *  configuration Job1 
   *  The tasks here can be configured and placed properties Or you could put it in a database  
   *  If you need to do dynamic timed tasks at this time, please refer to: http://blog.csdn.net/liuchuanhong1/article/details/60873295 
   *  In the blog ScheduleRefreshDatabase class  
   * @param scheduler 
   * @throws SchedulerException 
   */ 
  private void scheduleJob1(Scheduler scheduler) throws SchedulerException{ 
    /* 
     *  Here you can first query the database by task name, if the task exists in the database, according to ScheduleRefreshDatabase Class, configuration of update tasks, and triggers  
     *  If the task is not found in the database at this point, follow the steps below to create it 1 Task, and configure the initialization parameters, and save the configuration to the database  
     */ 
    JobDetail jobDetail = JobBuilder.newJob(ScheduledJob.class) .withIdentity("job1", "group1").build();  
    //  every 5s perform 1 time  
    CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ?");  
    CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1") .withSchedule(scheduleBuilder).build();  
    scheduler.scheduleJob(jobDetail,cronTrigger);  
  }    
  /** 
   *  configuration Job 
   * @param scheduler 
   * @throws SchedulerException 
   */ 
  private void scheduleJob2(Scheduler scheduler) throws SchedulerException{  
    JobDetail jobDetail = JobBuilder.newJob(ScheduledJob2.class) .withIdentity("job2", "group1").build(); 
    CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/10 * * * * ?");  
    //  every 10s perform 1 time  
    CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("trigger2", "group1") .withSchedule(scheduleBuilder).build();  
    scheduler.scheduleJob(jobDetail,cronTrigger); 
  } 
} 

3. Start two tasks

@Configuration 
@EnableScheduling 
@Component 
public class SchedulerListener {    
  @Autowired 
  public SchedulerAllJob myScheduler;    
  /** 
   *  Execute the method on startup, or use ApplicationListener , executes the method on startup  
   *  For specific use, please refer to: http://blog.csdn.net/liuchuanhong1/article/details/77568187 
   * @throws SchedulerException 
   */ 
  @Scheduled(cron="0 08 18 ? * *") 
  public void schedule() throws SchedulerException {  
      myScheduler.scheduleJobs(); 
   }  
   
  @Bean 
  public SchedulerFactoryBean schedulerFactoryBean(){ 
    SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();  
    return schedulerFactoryBean;  
  } 
} 

4. The test results are as follows

schedule job1 is running .....................................................................   
schedule job2 is running  .........................................................................................................  
schedule job1 is running .....................................................................   
schedule job1 is running .....................................................................   
schedule job2 is running  .........................................................................................................  
schedule job1 is running .....................................................................   
schedule job1 is running .....................................................................   
schedule job2 is running  .........................................................................................................  
schedule job1 is running .....................................................................
