* {@link FactoryBean} that creates and configures a Quartz {@link org.quartz.Scheduler},
* manages its lifecycle as part of the Spring application context, and exposes the
* Scheduler as bean reference for dependency injection.
*
* <p>Allows registration of JobDetails, Calendars and Triggers, automatically
* starting the scheduler on initialization and shutting it down on destruction.
* In scenarios that just require static registration of jobs at startup, there
* is no need to access the Scheduler instance itself in application code.
*
* <p>For dynamic registration of jobs at runtime, use a bean reference to
* this SchedulerFactoryBean to get direct access to the Quartz Scheduler
* ({@code org.quartz.Scheduler}). This allows you to create new jobs
* and triggers, and also to control and monitor the entire Scheduler.
*
* <p>Note that Quartz instantiates a new Job for each execution, in
* contrast to Timer which uses a TimerTask instance that is shared
* between repeated executions. Just JobDetail descriptors are shared.
*
* <p>When using persistent jobs, it is strongly recommended to perform all
* operations on the Scheduler within Spring-managed (or plain JTA) transactions.
* Else, database locking will not properly work and might even break.
* (See {@link #setDataSource setDataSource} javadoc for details.)
*
* <p>The preferred way to achieve transactional execution is to demarcate
* declarative transactions at the business facade level, which will
* automatically apply to Scheduler operations performed within those scopes.
* Alternatively, you may add transactional advice for the Scheduler itself.
*
* <p>Compatible with Quartz 2.1.4 and higher, as of Spring 4.1.

的全部属性如下图:

详解:

applicationContextSchedulerContextKey

Register ApplicationContext in Scheduler context.

从Scheduler上下文中获取ApplicationContext, 通过其指定的key获取。

startupDelay 

延迟秒

overwriteExistingJobs

重写已存在的任务(我认为会更新数据库)

dataSource

设置数据源

configLocation

设置配置文件例如:classpath:quartz/quartz.properties

exposeSchedulerInRepository

监控

taskExecutor

执行器

triggers

触发器
