SingularSchedulerBean

public SingularSchedulerBean(DataSource dataSource)

Method Detail

getConfigTimeTaskExecutor

public static Executor getConfigTimeTaskExecutor()

Return the TaskExecutor for the currently configured Quartz Scheduler, to be used by LocalTaskExecutorThreadPool.

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

See Also:

setTaskExecutor(java.util.concurrent.Executor), LocalTaskExecutorThreadPool

getConfigTimeDataSource

public static DataSource getConfigTimeDataSource()

Return the DataSource for the currently configured Quartz Scheduler, to be used by SingularLocalDataSourceJobStore.

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

See Also:

setDataSource(javax.sql.DataSource), SingularLocalDataSourceJobStore

getConfigTimeNonTransactionalDataSource

public static DataSource getConfigTimeNonTransactionalDataSource()

Return the non-transactional DataSource for the currently configured Quartz Scheduler, to be used by SingularLocalDataSourceJobStore.

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

See Also:

setNonTransactionalDataSource(javax.sql.DataSource), SingularLocalDataSourceJobStore

setSchedulerFactoryClass

public void setSchedulerFactoryClass(Class<? extends org.quartz.SchedulerFactory> schedulerFactoryClass)

Set the Quartz SchedulerFactory implementation to use.

Default is StdSchedulerFactory, reading in the standard quartz.properties from quartz.jar. To use custom Quartz properties, specify the "configLocation" or "quartzProperties" bean property on this FactoryBean.

See Also:

StdSchedulerFactory, setConfigLocation(java.util.ResourceBundle), setQuartzProperties(java.util.Properties)

setSchedulerName

public void setSchedulerName(String schedulerName)

Set the name of the Scheduler to create via the SchedulerFactory.

If not specified, the bean name will be used as default scheduler name.

Specified by:

setSchedulerName in interface org.opensingular.schedule.quartz.SingularQuartzSchedulerAcessor

See Also:

SchedulerFactory.getScheduler(), SchedulerFactory.getScheduler(String)

setConfigLocation

public void setConfigLocation(ResourceBundle configLocation)

Specified by:

setConfigLocation in interface org.opensingular.schedule.quartz.SingularQuartzSchedulerAcessor

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(java.util.Properties)

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.

Specified by:

setQuartzProperties in interface org.opensingular.schedule.quartz.SingularQuartzSchedulerAcessor

See Also:

setConfigLocation(java.util.ResourceBundle)

setTaskExecutor

public void setTaskExecutor(Executor taskExecutor)

Set the Spring TaskExecutor to use as Quartz backend. Exposed as thread pool through the Quartz SPI.

Can be used to assign a JDK 1.5 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.

See Also:

setQuartzProperties(java.util.Properties), LocalTaskExecutorThreadPool, org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor, org.springframework.scheduling.commonj.WorkManagerTaskExecutor

setDataSource

public void setDataSource(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.

See Also:

setNonTransactionalDataSource(javax.sql.DataSource), setQuartzProperties(java.util.Properties), SingularLocalDataSourceJobStore

setNonTransactionalDataSource

public void setNonTransactionalDataSource(DataSource nonTransactionalDataSource)

Set the DataSource to be used by the Scheduler 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.

See Also:

setDataSource(javax.sql.DataSource), SingularLocalDataSourceJobStore

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 - 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(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(org.quartz.spi.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.

Specified by:

setJobFactory in interface org.opensingular.schedule.quartz.SingularQuartzSchedulerAcessor

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.

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.

Specified by:

setExposeSchedulerInRepository in interface org.opensingular.schedule.quartz.SingularQuartzSchedulerAcessor

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.

Specified by:

setWaitForJobsToCompleteOnShutdown in interface org.opensingular.schedule.quartz.SingularQuartzSchedulerAcessor
