Class SchedulerFactoryBean

  • All Implemented Interfaces:
    Aware, BeanNameAware, DisposableBean, FactoryBean<Scheduler>, InitializingBean, ApplicationContextAware, Lifecycle, Phased, ResourceLoaderAware, SmartLifecycle

    public class SchedulerFactoryBean
extends SchedulerAccessor
implements FactoryBean<Scheduler>, BeanNameAware, ApplicationContextAware, InitializingBean, DisposableBean, 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.

      • getConfigTimeDataSource

        @Nullable
public static javax.sql.DataSource getConfigTimeDataSource()
        Return the DataSource for the currently configured Quartz Scheduler, to be used by LocalDataSourceJobStore.

        This instance will be set before initialization of the corresponding Scheduler, and reset immediately afterwards. It is thus only available during configuration.

      • setConfigLocation

        public void setConfigLocation(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.

        setQuartzProperties(java.util.Properties)

      • setQuartzProperties

        public void setQuartzProperties(java.util.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.

        setConfigLocation(org.springframework.core.io.Resource)

      • setTaskExecutor

        public void setTaskExecutor(java.util.concurrent.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.

        2.0

        setQuartzProperties(java.util.Properties), LocalTaskExecutorThreadPool, ThreadPoolTaskExecutor, DefaultManagedTaskExecutor

      • setDataSource

        public void setDataSource(javax.sql.DataSource dataSource)
        Set the default DataSource to be used by the Scheduler. If set, this will override corresponding settings in Quartz properties.

        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.

        Since:
        1.1

      • setNonTransactionalDataSource

        public void setNonTransactionalDataSource(javax.sql.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.

        1.1

        setDataSource(javax.sql.DataSource), LocalDataSourceJobStore

      • setSchedulerContextAsMap

        public void setSchedulerContextAsMap(java.util.Map<java.lang.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:
        JobDetailFactoryBean.setJobDataAsMap(java.util.Map<java.lang.String, ?>)

      • setApplicationContextSchedulerContextKey

        public void setApplicationContextSchedulerContextKey(java.lang.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:
        JobDetailFactoryBean.setApplicationContextJobDataKey(java.lang.String), ApplicationContext

      • 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.

        2.0
        See Also:
        AdaptableJobFactory, SpringBeanJobFactory

      • 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.

      • 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

      • 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.

        See Also:
        Scheduler.shutdown(boolean)

      • setBeanName

        public void setBeanName(java.lang.String name)
        Description copied from interface: BeanNameAware
        Set the name of the bean in the bean factory that created this bean.

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

        Specified by:
        setBeanName in interface BeanNameAware
        Parameters:
        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.

      • afterPropertiesSet

        public void afterPropertiesSet()
                        throws java.lang.Exception
        Description copied from interface: InitializingBean
        Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

        This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

        Specified by:
        afterPropertiesSet in interface InitializingBean
        Throws:
        java.lang.Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason

      • 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

      • getObject

        @Nullable
public Scheduler getObject()
        Description copied from interface: FactoryBean
        Return an instance (possibly shared or independent) of the object managed by this factory.

        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.

        Specified by:
        getObject in interface FactoryBean<Scheduler>
        Returns:
        an instance of the bean (can be null)
        See Also:
        FactoryBeanNotInitializedException

      • getObjectType

        public java.lang.Class<? extends Scheduler> getObjectType()
        Description copied from interface: FactoryBean
        Return the type of object that this FactoryBean creates, or 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.

        Specified by:
        getObjectType in interface FactoryBean<Scheduler>
        Returns:
        the type of object that this FactoryBean creates, or null if not known at the time of the call
        See Also:
        ListableBeanFactory.getBeansOfType(java.lang.Class<T>)

      • isSingleton

        public boolean isSingleton()
        Description copied from interface: FactoryBean
        Is the object managed by this factory a singleton? That is, will 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.

        The default implementation returns true, since a FactoryBean typically manages a singleton instance.

        Specified by:
        isSingleton in interface FactoryBean<Scheduler>
        Returns:
        whether the exposed object is a singleton
        See Also:
        FactoryBean.getObject(), SmartFactoryBean.isPrototype()

      • stop

        public void stop()
          throws SchedulingException
        Description copied from interface: Lifecycle
        Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method. Consider implementing SmartLifecycle and its stop(Runnable) variant when asynchronous stop behavior is necessary.

        Note that this stop notification is not guaranteed to come before destruction: On regular shutdown, Lifecycle beans will first receive a stop notification before the general destruction callbacks are being propagated; however, on hot refresh during a context's lifetime or on aborted refresh attempts, a given bean's destroy method will be called without any consideration of stop signals upfront.

        Should not throw an exception if the component is not running (not started yet).

        In the case of a container, this will propagate the stop signal to all components that apply.

        Specified by:
        stop in interface Lifecycle
        Throws:
        SchedulingException
        See Also:
        SmartLifecycle.stop(Runnable), DisposableBean.destroy()

      • isRunning

        public boolean isRunning()
                  throws SchedulingException
        Description copied from interface: Lifecycle
        Check whether this component is currently running.

        In the case of a container, this will return true only if all components that apply are currently running.

        Specified by:
        isRunning in interface Lifecycle
        Returns:
        whether the component is currently running
        Throws:
        SchedulingException
