Class SchedulerAccessor

java.lang.Object

org.springframework.scheduling.quartz.SchedulerAccessor

All Implemented Interfaces:

Aware, ResourceLoaderAware

Direct Known Subclasses:

SchedulerAccessorBean, SchedulerFactoryBean

public abstract class SchedulerAccessor
extends Object
implements ResourceLoaderAware

Common base class for accessing a Quartz Scheduler, i.e. for registering jobs, triggers and listeners on a Scheduler instance.

For concrete usage, check out the SchedulerFactoryBean and SchedulerAccessorBean classes.

Compatible with Quartz 1.5+ as well as Quartz 2.0/2.1, as of Spring 3.1.

Since:

2.5.6

Method Detail

setOverwriteExistingJobs

public void setOverwriteExistingJobs(boolean overwriteExistingJobs)

Set whether any jobs defined on this SchedulerFactoryBean should overwrite existing job definitions. Default is "false", to not overwrite already registered jobs that have been read in from a persistent job store.

setJobSchedulingDataLocation

public void setJobSchedulingDataLocation(String jobSchedulingDataLocation)

Set the location of a Quartz job definition XML file that follows the "job_scheduling_data_1_5" XSD or better. Can be specified to automatically register jobs that are defined in such a file, possibly in addition to jobs defined directly on this SchedulerFactoryBean.

See Also:

XmlSchedulingDataProcessor

setJobSchedulingDataLocations

public void setJobSchedulingDataLocations(String[] jobSchedulingDataLocations)

Set the locations of Quartz job definition XML files that follow the "job_scheduling_data_1_5" XSD or better. Can be specified to automatically register jobs that are defined in such files, possibly in addition to jobs defined directly on this SchedulerFactoryBean.

See Also:

XmlSchedulingDataProcessor

setJobDetails

public void setJobDetails(JobDetail[] jobDetails)

Register a list of JobDetail objects with the Scheduler that this FactoryBean creates, to be referenced by Triggers.

This is not necessary when a Trigger determines the JobDetail itself: In this case, the JobDetail will be implicitly registered in combination with the Trigger.

See Also:

setTriggers(org.quartz.Trigger[]), JobDetail, JobDetailBean, JobDetailAwareTrigger, Trigger.setJobName(java.lang.String)

setCalendars

public void setCalendars(Map<String,Calendar> calendars)

Register a list of Quartz Calendar objects with the Scheduler that this FactoryBean creates, to be referenced by Triggers.

Parameters:

calendars - Map with calendar names as keys as Calendar objects as values

See Also:

Calendar, Trigger.setCalendarName(java.lang.String)

setTriggers

public void setTriggers(Trigger[] triggers)

Register a list of Trigger objects with the Scheduler that this FactoryBean creates.

If the Trigger determines the corresponding JobDetail itself, the job will be automatically registered with the Scheduler. Else, the respective JobDetail needs to be registered via the "jobDetails" property of this FactoryBean.

See Also:

setJobDetails(org.quartz.JobDetail[]), JobDetail, JobDetailAwareTrigger, CronTriggerBean, SimpleTriggerBean

setSchedulerListeners

public void setSchedulerListeners(SchedulerListener[] schedulerListeners)

Specify Quartz SchedulerListeners to be registered with the Scheduler.

setGlobalJobListeners

public void setGlobalJobListeners(JobListener[] globalJobListeners)

Specify global Quartz JobListeners to be registered with the Scheduler. Such JobListeners will apply to all Jobs in the Scheduler.

setJobListeners

public void setJobListeners(JobListener[] jobListeners)

Specify named Quartz JobListeners to be registered with the Scheduler. Such JobListeners will only apply to Jobs that explicitly activate them via their name.

See Also:

JobListener.getName(), JobDetail.addJobListener(java.lang.String), JobDetailBean.setJobListenerNames(java.lang.String[])

setGlobalTriggerListeners

public void setGlobalTriggerListeners(TriggerListener[] globalTriggerListeners)

Specify global Quartz TriggerListeners to be registered with the Scheduler. Such TriggerListeners will apply to all Triggers in the Scheduler.

setTriggerListeners

public void setTriggerListeners(TriggerListener[] triggerListeners)

Specify named Quartz TriggerListeners to be registered with the Scheduler. Such TriggerListeners will only apply to Triggers that explicitly activate them via their name.

See Also:

TriggerListener.getName(), Trigger.addTriggerListener(java.lang.String), CronTriggerBean.setTriggerListenerNames(java.lang.String[]), SimpleTriggerBean.setTriggerListenerNames(java.lang.String[])

setTransactionManager

public void setTransactionManager(PlatformTransactionManager transactionManager)

Set the transaction manager to be used for registering jobs and triggers that are defined by this SchedulerFactoryBean. Default is none; setting this only makes sense when specifying a DataSource for the Scheduler.

setResourceLoader

public void setResourceLoader(ResourceLoader resourceLoader)

Description copied from interface: ResourceLoaderAware

Set the ResourceLoader that this object runs in.

This might be a ResourcePatternResolver, which can be checked through instanceof ResourcePatternResolver. See also the ResourcePatternUtils.getResourcePatternResolver method.

Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked before ApplicationContextAware's setApplicationContext.

Specified by:

setResourceLoader in interface ResourceLoaderAware

Parameters:

resourceLoader - ResourceLoader object to be used by this object

See Also:

ResourcePatternResolver, ResourcePatternUtils.getResourcePatternResolver(org.springframework.core.io.ResourceLoader)

registerJobsAndTriggers

protected void registerJobsAndTriggers()
                                throws SchedulerException

Register jobs and triggers (within a transaction, if possible).

Throws:

SchedulerException

registerListeners

protected void registerListeners()
                          throws SchedulerException

Register all specified listeners with the Scheduler.

Throws:

SchedulerException

getScheduler

protected abstract Scheduler getScheduler()

Template method that determines the Scheduler to operate on. To be implemented by subclasses.
