Question

我已经为Java项目实现了Quartz调度程序。我还配置了JDBCJobStore来存储MySQL数据库中的所有作业，以便它可以在重启后恢复作业。我现在遇到的问题是，调度程序在启动应用程序时不会恢复任何作业。当我注释掉JDBCJobStore配置时，调度程序按预期工作，但它只适用于JDBCJobStore配置。我在下面添加了类和配置文件。我错过了什么吗？任何帮助都将受到高度赞赏。

FutureEventScheduler.java

public class FutureEventScheduler {
  private Scheduler scheduler = null;
  private JobDetail job;
  private Trigger trigger;
  private Logger logger = Logger.getLogger(FutureEventScheduler.class);

  private void initialize() {
    try {
      scheduler = new StdSchedulerFactory().getScheduler();
      job = JobBuilder.newJob(FutureEventSchedulerJob.class).withIdentity("Future Event Job", Config.getSdkName()).requestRecovery(true).storeDurably(true).build();
      trigger = TriggerBuilder.newTrigger().withIdentity("Future Event Trigger", Config.getSdkName()).withSchedule(
          CronScheduleBuilder.cronSchedule("*/3 * * * * ?")
      ).build();

    } catch (SchedulerException e) {
      logger.error(e.getMessage(), e);
    }
  }

  public FutureEventScheduler() {
    initialize();
  }

  public void start() throws SchedulerException {
    scheduler.start();
    try {
      scheduler.scheduleJob(job, trigger);
    } catch (ObjectAlreadyExistsException e) {
      logger.info("Already exists in database. Will restore it. " + e.getMessage());
    }
  }

  public void stop() throws SchedulerException {
    scheduler.shutdown();
  }

FutureEventSchedulerJob.java

public class FutureEventSchedulerJob implements Job {

  private static Logger logger = Logger.getLogger(FutureEventSchedulerJob.class);

  @Override
  public void execute(JobExecutionContext context) throws JobExecutionException {

    logger.debug("future job");

  }
}
