A Spring FactoryBean for creating a Quartz org.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 org.quartz.JobDetail. This allows SchedulerFactoryBean to automatically register a trigger for the corresponding JobDetail, instead of registering the JobDetail separately.

Method Detail

afterPropertiesSetback to summary
public void afterPropertiesSet() throws ParseException

Implements org.springframework.beans.factory.InitializingBean.afterPropertiesSet.

Doc from org.springframework.beans.factory.InitializingBean.afterPropertiesSet.

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.

Annotations
@Override
getJobDataMapback to summary
public org.quartz.JobDataMap getJobDataMap()

Return the trigger's JobDataMap.

getObjectback to summary
public org.quartz.CronTrigger getObject()

Implements org.springframework.beans.factory.FactoryBean.getObject.

Doc from org.springframework.beans.factory.FactoryBean.getObject.

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.

Returns:org.quartz.CronTrigger

an instance of the bean (can be null)

Annotations
@Override
@Nullable
getObjectTypeback to summary
public Class<?> getObjectType()

Implements org.springframework.beans.factory.FactoryBean.getObjectType.

Doc from org.springframework.beans.factory.FactoryBean.getObjectType.

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.

Returns:Class<?>

the type of object that this FactoryBean creates, or null if not known at the time of the call

Annotations
@Override
isSingletonback to summary
public boolean isSingleton()

Overrides default org.springframework.beans.factory.FactoryBean.isSingleton.

Doc from org.springframework.beans.factory.FactoryBean.isSingleton.

Is the object managed by this factory a singleton? That is, will 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.

Returns:boolean

whether the exposed object is a singleton

Annotations
@Override
setBeanNameback to summary
public void setBeanName(String beanName)

Implements org.springframework.beans.factory.BeanNameAware.setBeanName.

Doc from org.springframework.beans.factory.BeanNameAware.setBeanName.

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.

Parameters
beanName:String

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.

Annotations
