Question

我想使用jdbc数据存储库立即通过石英调度程序执行作业。但是，即使我使用now（）或调用triggerJob进行调度，在调度和触发火灾之间也要延迟20-30秒。

我试图用一个简单的触发器来执行作业：

JobKey key = //...
        JobDetail jobDetail = newJob(jobBean.getClass())
                .withIdentity(key)
                .usingJobData(new JobDataMap(jobParams))
                .storeDurably()
                .build();

        Trigger trigger = newTrigger()
                .withIdentity(key.getName(), key.getGroup())
                .startNow()
                .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                        .withMisfireHandlingInstructionFireNow()
                        .withRepeatCount(0))
                .build();

        scheduler.scheduleJob(jobDetail, trigger);

我还尝试使用调度程序进行触发：

 JobKey key = // ...
        JobDetail jobDetail = newJob(jobBean.getClass())
                .withIdentity(key)
                .storeDurably()
                .build();
        scheduler.addJob(jobDetail, true);


        scheduler.triggerJob(key, new JobDataMap(jobParams));

以下是显示延迟的侦听器日志。

我到处都发现面包屑，这表明问题与交易有关。因此，我从服务方法中删除了@Transactional，并且它起作用了。看起来像当您调用触发器时，调度程序线程尝试从数据库中查找调度和触发器，但此时未提交事务。稍后，调度程序线程再次查找数据库，并最终找到它。

石英触发器不会立即触发
