If Quartz scheduler is not set to start automatically. You need to start it explicitly.
scheduler.start();
If Quartz scheduler started successful, you should see information in your log or console output similar as below.
[main] INFO org.quartz.core.QuartzScheduler - Scheduler meta-data: Quartz Scheduler (v2.2.1)
'org.springframework.scheduling.quartz.SchedulerFactoryBean#0' with instanceId 'MyScheduler'
Scheduler class: 'org.quartz.core.QuartzScheduler' - running locally.
NOT STARTED.
Currently in standby mode.
Number of jobs executed: 0
Using thread pool 'org.quartz.simpl.SimpleThreadPool' - with 10 threads.
Using job-store 'org.quartz.simpl.RAMJobStore' - which does not support persistence. and is not clustered.
...
[main] INFO org.quartz.core.QuartzScheduler - started

Finally I found solution for my problem, after enabling quartz log4j (adding log4j.logger.org.quartz=DEBUG in my log4j.properties ), I saw the jdbc exception in console, the exception related to using outdated quartz-query.
I added quartz 2.2.1 dependency in my POM but I used quartz sql query for 2.1.7 version and that mismatched between quartz jar and quartz sql query version cause missing some table like SCHED_TIME.
