Spring boot and Quartz - Job not executing immediately

Question

I am configuring Quartz job with Spring boot. The requirement is to execute the job immediately without attaching any schedule.

Here is what my code looks like

JobDetailFactoryBean factoryBean = new JobDetailFactoryBean();

String jobName = jobName(taskContext);

factoryBean.setJobClass(MyJobClass.class);
factoryBean.setDurability(true);
factoryBean.setApplicationContext(applicationContext);
factoryBean.setName("Hello job");
factoryBean.setGroup("Hello job group");

JobDataMap jobData = new JobDataMap(new HashMap<>());
factoryBean.setJobDataMap(jobData);
factoryBean.afterPropertiesSet();

JobDetail job = factoryBean.getObject();
Scheduler scheduler = schedulerFactoryBean.getScheduler();
scheduler.addJob(job, replace);
scheduler.triggerJob(job.getKey());

And here is how quartz.properties looks like

org.quartz.scheduler.instanceName=springBootQuartzApp
org.quartz.scheduler.instanceId=AUTO
org.quartz.threadPool.threadCount=10
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
org.quartz.jobStore.useProperties=true
org.quartz.jobStore.misfireThreshold=2000
org.quartz.jobStore.tablePrefix=qrtz_
org.quartz.jobStore.isClustered=false
org.quartz.plugin.shutdownHook.class=org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownHook.cleanShutdown=TRUE

The problem is that the job is not firing immediately and is getting picked up as misfire instruction. It is executed right exactly after the misfireThreshold.

Please let me know, if I have missed something in the configuration or didn't call any appropriate API.

I got the same issue.

If your quartz is using a data source with transaction: @EnableTransactionManagement. Please add @Transactional to the method of your code, then the transaction is committed immediately. Later the scheduler thread looks up the db again and fire it finally.
