java.lang.Object org.springframework.scheduling.quartz.SchedulerAccessor org.springframework.scheduling.quartz.SchedulerFactoryBean
public class SchedulerFactoryBean
FactoryBean
that creates and configures a Quartz Scheduler
,
manages its lifecycle as part of the Spring application context, and exposes the
Scheduler as bean reference for dependency injection.
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.
For dynamic registration of jobs at runtime, use a bean reference to
this SchedulerFactoryBean to get direct access to the Quartz Scheduler
(org.quartz.Scheduler
). This allows you to create new jobs
and triggers, and also to control and monitor the entire Scheduler.
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.
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 setDataSource
javadoc for details.)
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.
Compatible with Quartz 1.5+ as well as Quartz 2.0/2.1, as of Spring 3.1.

public void setDataSource(DataSource dataSource)
Note: If this is set, the Quartz settings should not define a job store "dataSource" to avoid meaningless double configuration.
A Spring-specific subclass of Quartz' JobStoreCMT will be used. It is therefore 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 (e.g. if trying to obtain a lock on Oracle without a transaction).
Supports both transactional and non-transactional DataSource access. With a non-XA DataSource and local Spring transactions, a single DataSource argument is sufficient. In case of an XA DataSource and global JTA transactions, SchedulerFactoryBean's "nonTransactionalDataSource" property should be set, passing in a non-XA DataSource that will not participate in global transactions.

public void setNonTransactionalDataSource(DataSource nonTransactionalDataSource)
This is only necessary if the default DataSource is an XA DataSource that will always participate in transactions: A non-XA version of that DataSource should be specified as "nonTransactionalDataSource" in such a scenario.
This is not relevant with a local DataSource instance and Spring transactions. Specifying a single default DataSource as "dataSource" is sufficient there.

public void setSchedulerContextAsMap(Map schedulerContextAsMap)
Note: When using persistent Jobs whose JobDetail will be kept in the database, do not put Spring-managed beans or an ApplicationContext reference into the JobDataMap but rather into the SchedulerContext.

values (for example Spring-managed beans)JobDetailBean.setJobDataAsMap(java.util.Map)
public void setApplicationContextSchedulerContextKey(String applicationContextSchedulerContextKey)
Note: When using persistent Jobs whose JobDetail will be kept in the database, do not put an ApplicationContext reference into the JobDataMap but rather into the SchedulerContext.
In case of a QuartzJobBean, the reference will be applied to the Job instance as bean property. An "applicationContext" attribute will correspond to a "setApplicationContext" method in that scenario.
Note that BeanFactory callback interfaces like ApplicationContextAware are not automatically applied to Quartz Job instances, because Quartz itself is reponsible for the lifecycle of its Jobs.

public void setJobFactory(org.quartz.spi.JobFactory jobFactory)
Default is Spring's AdaptableJobFactory
, which supports
Runnable
objects as well as standard Quartz
Job
instances. Note that this default only applies
to a local Scheduler, not to a RemoteScheduler (where setting
a custom JobFactory is not supported by Quartz).
Specify an instance of Spring's SpringBeanJobFactory
here
(typically as an inner bean definition) to automatically populate a job's
bean properties from the specified job data map and scheduler context.

Setting this to 10 or 20 seconds makes sense if no jobs should be run before the entire application has started up.
public void setExposeSchedulerInRepository(boolean exposeSchedulerInRepository)
Scheduler
instance in the
Quartz SchedulerRepository
. Default is "false", since the Spring-managed
Scheduler is usually exclusively intended for access within the Spring context.
Switch this flag to "true" in order to expose the Scheduler globally. This is not recommended unless you have an existing Spring application that relies on this behavior. Note that such global exposure was the accidental default in earlier Spring versions; this has been fixed as of Spring 2.5.6.
public void setWaitForJobsToCompleteOnShutdown(boolean waitForJobsToCompleteOnShutdown)
Default is "false". Switch this to "true" if you prefer fully completed jobs at the expense of a longer shutdown phase.

BeanNameAware
Invoked after population of normal bean properties but before an
init callback such as InitializingBean.afterPropertiesSet()
or a custom init-method.
setBeanName

name
- the name of the bean in the factory.
Note that this name is the actual bean name used in the factory, which may
differ from the originally specified name: in particular for inner bean
names, the actual bean name might have been made unique through appending
"#..." suffixes. Use the BeanFactoryUtils.originalBeanName(String)
method to extract the original bean name (without suffix), if desired.public void setApplicationContext(ApplicationContext applicationContext)
ApplicationContextAware
Invoked after population of normal bean properties but before an init callback such
as InitializingBean.afterPropertiesSet()
or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader)

FactoryBean
As with a BeanFactory
, this allows support for both the
Singleton and Prototype design pattern.
If this FactoryBean is not fully initialized yet at the time of
the call (for example because it is involved in a circular reference),
throw a corresponding FactoryBeanNotInitializedException
.
As of Spring 2.0, FactoryBeans are allowed to return null
objects. The factory will consider this as normal value to be used; it
will not throw a FactoryBeanNotInitializedException in this case anymore.
FactoryBean implementations are encouraged to throw
FactoryBeanNotInitializedException themselves now, as appropriate.

public Class<? extends Scheduler> getObjectType()

null
if not known in advance.
This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return
null
here. Therefore it is highly recommended to implement
this method properly, using the current state of the FactoryBean.

FactoryBean.getObject()
always return the same object
(a reference that can be cached)?
NOTE: If a FactoryBean indicates to hold a singleton object,
the object returned from getObject()
might get cached
by the owning BeanFactory. Hence, do not return true
unless the FactoryBean always exposes the same reference.
The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
NOTE: This method returning false
does not
necessarily indicate that returned objects are independent instances.
An implementation of the extended SmartFactoryBean
interface
may explicitly indicate independent instances through its
SmartFactoryBean.isPrototype()
method. Plain FactoryBean
implementations which do not implement this extended interface are
simply assumed to always return independent instances if the
isSingleton()
implementation returns false
.
