Class CronTriggerBean

java.lang.Object
  extended by org.quartz.Trigger
      extended by org.quartz.CronTrigger
          extended by org.springframework.scheduling.quartz.CronTriggerBean
All Implemented Interfaces:
Serializable, Cloneable, Comparable, BeanNameAware, InitializingBean, JobDetailAwareTrigger

public class CronTriggerBean
extends CronTrigger
implements JobDetailAwareTrigger, BeanNameAware, InitializingBean

Convenience subclass of Quartz's CronTrigger class, making bean-style usage easier.

CronTrigger itself is already a JavaBean but lacks sensible defaults. This class uses the Spring bean name as job name, the Quartz default group ("DEFAULT") as job group, the current time as start time, and indefinite repetition, if not specified.

This class will also register the trigger with the job name and group of a given JobDetail. This allows SchedulerFactoryBean to automatically register a trigger for the corresponding JobDetail, instead of registering the JobDetail separately.

NOTE: This convenience subclass does not work with trigger persistence in Quartz 1.6, due to a change in Quartz's trigger handling. Use Quartz 1.5 if you rely on trigger persistence based on this class, or the standard Quartz CronTrigger class instead.

Constructor Detail

CronTriggerBean

public CronTriggerBean()
Method Detail

setMisfireInstructionName

public void setMisfireInstructionName(String constantName)
Set the misfire instruction via the name of the corresponding constant in the CronTrigger class. Default is MISFIRE_INSTRUCTION_SMART_POLICY.

See Also:
CronTrigger.MISFIRE_INSTRUCTION_FIRE_ONCE_NOW, CronTrigger.MISFIRE_INSTRUCTION_DO_NOTHING, Trigger.MISFIRE_INSTRUCTION_SMART_POLICY

setTriggerListenerNames

public void setTriggerListenerNames(String[] names)
Set a list of TriggerListener names for this job, referring to non-global TriggerListeners registered with the Scheduler.

A TriggerListener name always refers to the name returned by the TriggerListener implementation.

See Also:
SchedulerFactoryBean.setTriggerListeners(org.quartz.TriggerListener[]), TriggerListener.getName()

setJobDetail

public void setJobDetail(JobDetail jobDetail)
Set the JobDetail that this trigger should be associated with.

This is typically used with a bean reference if the JobDetail is a Spring-managed bean. Alternatively, the trigger can also be associated with a job by name and group.

See Also:
Trigger.setJobName(java.lang.String), Trigger.setJobGroup(java.lang.String)

getJobDetail

public JobDetail getJobDetail()
Description copied from interface: JobDetailAwareTrigger
Return the JobDetail that this Trigger is associated with.

Specified by:
getJobDetail in interface JobDetailAwareTrigger
Returns:
the associated JobDetail, or null if none

setBeanName

public void setBeanName(String beanName)
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 like InitializingBean's afterPropertiesSet or a custom init-method.

Specified by:
setBeanName in interface BeanNameAware
Parameters:
beanName - the name of the bean in the factory

afterPropertiesSet

public void afterPropertiesSet()
                        throws ParseException
Description copied from interface: InitializingBean
Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:
afterPropertiesSet in interface InitializingBean
Throws:
ParseException
