Class CronTriggerFactoryBean

All Implemented Interfaces:
Aware, BeanNameAware, FactoryBean<CronTrigger>, InitializingBean

public class CronTriggerFactoryBean extends Object implements FactoryBean<CronTrigger>, BeanNameAware, InitializingBean
A Spring FactoryBean for creating a Quartz CronTrigger instance, supporting bean-style usage for trigger configuration.

CronTrigger(Impl) 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.

    • setName

      public void setName(String name)
      Specify the trigger's name.
    • setGroup

      public void setGroup(String group)
      Specify the trigger's group.
    • setJobDetail

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

      public void setJobDataMap(JobDataMap jobDataMap)
      Set the trigger's JobDataMap.
      See Also:
    • getJobDataMap

      public JobDataMap getJobDataMap()
      Return the trigger's JobDataMap.
    • setJobDataAsMap

      public void setJobDataAsMap(Map<String,?> jobDataAsMap)
      Register objects in the JobDataMap via a given Map.

      These objects will be available to this Trigger only, in contrast to objects in the JobDetail's data map.

      jobDataAsMap - a Map with String keys and any objects as values (for example Spring-managed beans)
    • setStartTime

      public void setStartTime(Date startTime)
      Set a specific start time for the trigger.

      Note that a dynamically computed setStartDelay(long) specification overrides a static timestamp set here.

    • setStartDelay

      public void setStartDelay(long startDelay)
      Set the start delay in milliseconds.

      The start delay is added to the current system time (when the bean starts) to control the start time of the trigger.

    • setCronExpression

      public void setCronExpression(String cronExpression)
      Specify the cron expression for this trigger.
    • setTimeZone

      public void setTimeZone(TimeZone timeZone)
      Specify the time zone for this trigger's cron expression.
    • setCalendarName

      public void setCalendarName(String calendarName)
      Associate a specific calendar with this cron trigger.
    • setPriority

      public void setPriority(int priority)
      Specify the priority of this trigger.
    • setMisfireInstruction

      public void setMisfireInstruction(int misfireInstruction)
      Specify a misfire instruction for this trigger.
    • 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:
    • setDescription

      public void setDescription(String description)
      Associate a textual description with this trigger.
    • 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 such as InitializingBean.afterPropertiesSet() or a custom init-method.

      Specified by:
      setBeanName in interface BeanNameAware
      beanName - 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 ParseException
      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
    • getObject

      @Nullable public CronTrigger 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<CronTrigger>
      an instance of the bean (can be null)
      See Also:
    • getObjectType

      public Class<?> 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<CronTrigger>
      the type of object that this FactoryBean creates, or null if not known at the time of the call
      See Also:
    • 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<CronTrigger>
      whether the exposed object is a singleton
