CronTriggerFactoryBean

java.lang.Object
- org.springframework.scheduling.quartz.CronTriggerFactoryBean

All Implemented Interfaces:

Aware, BeanNameAware, FactoryBean<CronTrigger>, InitializingBean
```
public class CronTriggerFactoryBean
extends java.lang.Object
implements FactoryBean<CronTrigger>, BeanNameAware, InitializingBean
```
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.

Since:

3.1

public void setDescription(java.lang.String description)
```

  - setBeanName
```
public void setBeanName(java.lang.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
    
    Parameters:
    
    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 java.text.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:
    
    java.text.ParseException
  - getObject
```
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>
    
    Returns:
    
    an instance of the bean (can be null)
    
    See Also:
    
    FactoryBeanNotInitializedException
  - getObjectType
```
public java.lang.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>
    
    Returns:
    
    the type of object that this FactoryBean creates, or null if not known at the time of the call
    
    See Also:
    
    ListableBeanFactory.getBeansOfType(java.lang.Class<T>)
  - 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.
    
    Specified by:
    
    isSingleton in interface FactoryBean<CronTrigger>
    
    Returns:
    
    whether the exposed object is a singleton
