All Implemented Interfaces:
org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.FactoryBean<Scheduler>, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.ResourceLoaderAware, org.springframework.context.SmartLifecycle
public class SchedulerFactoryBean extends SchedulerAccessor implements org.springframework.beans.factory.FactoryBean<Scheduler>, org.springframework.beans.factory.BeanNameAware, org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean, org.springframework.context.SmartLifecycle
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 2.1.4 and higher, as of Spring 4.1.

      See Also:

    • setSchedulerFactory

      public void setSchedulerFactory(SchedulerFactory schedulerFactory)
      Set an external Quartz SchedulerFactory instance to use.

      Default is an internal StdSchedulerFactory instance. If this method is called, it overrides any class specified through setSchedulerFactoryClass(java.lang.Class<? extends org.quartz.SchedulerFactory>) as well as any settings specified through setConfigLocation(org.springframework.core.io.Resource), setQuartzProperties(java.util.Properties), setTaskExecutor(java.util.concurrent.Executor) or setDataSource(javax.sql.DataSource).

      NOTE: With an externally provided SchedulerFactory instance, local settings such as setConfigLocation(org.springframework.core.io.Resource) or setQuartzProperties(java.util.Properties) will be ignored here in SchedulerFactoryBean, expecting the external SchedulerFactory instance to get initialized on its own.

      Since:
      4.3.15
      See Also:

    • setSchedulerFactoryClass

      public void setSchedulerFactoryClass(Class<? extends SchedulerFactory> schedulerFactoryClass)
      Set the Quartz SchedulerFactory implementation to use.

      Default is the StdSchedulerFactory class, reading in the standard quartz.properties from quartz.jar. For applying custom Quartz properties, specify "configLocation" and/or "quartzProperties" etc on this local SchedulerFactoryBean instance.

      See Also:

    • setSchedulerName

      public void setSchedulerName(String schedulerName)
      Set the name of the Scheduler to create via the SchedulerFactory, as an alternative to the org.quartz.scheduler.instanceName property.

      If not specified, the name will be taken from Quartz properties (org.quartz.scheduler.instanceName), or from the declared SchedulerFactoryBean bean name as a fallback.

      See Also:

    • setConfigLocation

      public void setConfigLocation(org.springframework.core.io.Resource configLocation)
      Set the location of the Quartz properties config file, for example as classpath resource "classpath:quartz.properties".

      Note: Can be omitted when all necessary properties are specified locally via this bean, or when relying on Quartz' default configuration.

      See Also:

    • setQuartzProperties

      public void setQuartzProperties(Properties quartzProperties)
      Set Quartz properties, like "org.quartz.threadPool.class".

      Can be used to override values in a Quartz properties config file, or to specify all necessary properties locally.

      See Also:

    • setTaskExecutor

      public void setTaskExecutor(Executor taskExecutor)
      Set a Spring-managed Executor to use as Quartz backend. Exposed as thread pool through the Quartz SPI.

      Can be used to assign a local JDK ThreadPoolExecutor or a CommonJ WorkManager as Quartz backend, to avoid Quartz's manual thread creation.

      By default, a Quartz SimpleThreadPool will be used, configured through the corresponding Quartz properties.

      Since:
      2.0
      See Also:

    • setDataSource

      public void setDataSource(DataSource dataSource)
      Set the default DataSource to be used by the Scheduler.

      Note: If this is set, the Quartz settings should not define a job store "dataSource" to avoid meaningless double configuration. Also, do not define a "org.quartz.jobStore.class" property at all. (You may explicitly define Spring's LocalDataSourceJobStore but that's the default when using this method anyway.)

      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 (for example, 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.

      Since:
      1.1
      See Also:

    • setNonTransactionalDataSource

      public void setNonTransactionalDataSource(DataSource nonTransactionalDataSource)
      Set the DataSource to be used for non-transactional access.

      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.

    • setSchedulerContextAsMap

      public void setSchedulerContextAsMap(Map<String,?> schedulerContextAsMap)
      Register objects in the Scheduler context via a given Map. These objects will be available to any Job that runs in this Scheduler.

      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.

      Parameters:
      schedulerContextAsMap - a Map with String keys and any objects as values (for example Spring-managed beans)
      See Also:

    • setApplicationContextSchedulerContextKey

      public void setApplicationContextSchedulerContextKey(String applicationContextSchedulerContextKey)
      Set the key of an ApplicationContext reference to expose in the SchedulerContext, for example "applicationContext". Default is none. Only applicable when running in a Spring ApplicationContext.

      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 responsible for the lifecycle of its Jobs.

      See Also:

    • setJobFactory

      public void setJobFactory(JobFactory jobFactory)
      Set the Quartz JobFactory to use for this Scheduler.

      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.

    • setAutoStartup

      public void setAutoStartup(boolean autoStartup)
      Set whether to automatically start the scheduler after initialization.

      Default is "true"; set this to "false" to allow for manual startup.

    • isAutoStartup

      public boolean isAutoStartup()
      Return whether this scheduler is configured for auto-startup. If "true", the scheduler will start after the context is refreshed and after the start delay, if any.
      Specified by:
      isAutoStartup in interface org.springframework.context.SmartLifecycle

    • setPhase

      public void setPhase(int phase)
      Specify the phase in which this scheduler should be started and stopped. The startup order proceeds from lowest to highest, and the shutdown order is the reverse of that. By default this value is Integer.MAX_VALUE meaning that this scheduler starts as late as possible and stops as soon as possible.
      Since:
      3.0

    • getPhase

      public int getPhase()
      Return the phase in which this scheduler will be started and stopped.
      Specified by:
      getPhase in interface org.springframework.context.Phased
      Specified by:
      getPhase in interface org.springframework.context.SmartLifecycle

    • setStartupDelay

      public void setStartupDelay(int startupDelay)
      Set the number of seconds to wait after initialization before starting the scheduler asynchronously. Default is 0, meaning immediate synchronous startup on initialization of this bean.

      Setting this to 10 or 20 seconds makes sense if no jobs should be run before the entire application has started up.

    • setExposeSchedulerInRepository

      public void setExposeSchedulerInRepository(boolean exposeSchedulerInRepository)
      Set whether to expose the Spring-managed 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.

    • setWaitForJobsToCompleteOnShutdown

      public void setWaitForJobsToCompleteOnShutdown(boolean waitForJobsToCompleteOnShutdown)
      Set whether to wait for running jobs to complete on shutdown.

      Default is "false". Switch this to "true" if you prefer fully completed jobs at the expense of a longer shutdown phase.

    • setBeanName

      public void setBeanName(String name)
      Specified by:
      setBeanName in interface org.springframework.beans.factory.BeanNameAware

    • setApplicationContext

      public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
      Specified by:
      setApplicationContext in interface org.springframework.context.ApplicationContextAware

    • afterPropertiesSet

      public void afterPropertiesSet() throws Exception
      Specified by:
      afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean
      Throws:
      Exception

    • createScheduler

      protected Scheduler createScheduler(SchedulerFactory schedulerFactory, @Nullable String schedulerName) throws SchedulerException
      Create the Scheduler instance for the given factory and scheduler name. Called by afterPropertiesSet().

      The default implementation invokes SchedulerFactory's getScheduler method. Can be overridden for custom Scheduler creation.

      Parameters:
      schedulerFactory - the factory to create the Scheduler with
      schedulerName - the name of the scheduler to create
      Returns:
      the Scheduler instance
      Throws:
      SchedulerException - if thrown by Quartz methods
      See Also:

    • startScheduler

      protected void startScheduler(Scheduler scheduler, int startupDelay) throws SchedulerException
      Start the Quartz Scheduler, respecting the "startupDelay" setting.
      Parameters:
      scheduler - the Scheduler to start
      startupDelay - the number of seconds to wait before starting the Scheduler asynchronously
      Throws:
      SchedulerException

    • getScheduler

      public Scheduler getScheduler()
