Class MethodInvokingTimerTaskFactoryBean

java.lang.Object
  org.springframework.util.MethodInvoker
      org.springframework.scheduling.timer.MethodInvokingTimerTaskFactoryBean

All Implemented Interfaces:

FactoryBean, InitializingBean

public class MethodInvokingTimerTaskFactoryBean

extends MethodInvoker

implements FactoryBean, InitializingBean

FactoryBean that exposes a TimerTask object that delegates job execution to a specified (static or non-static) method. Avoids the need to implement a one-line TimerTask that just invokes an existing business method.

Derived from MethodInvoker to share common properties and behavior with MethodInvokingFactoryBean.

Method Summary

void	afterPropertiesSet() Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).
java.lang.Object	getObject() Return an instance (possibly shared or independent) of the object managed by this factory.
java.lang.Class	getObjectType() Return the type of object that this FactoryBean creates, or null if not known in advance.
boolean	isSingleton() Is the bean managed by this factory a singleton or a prototype? That is, will getObject() always return the same object?

Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.ClassNotFoundException,
                               java.lang.NoSuchMethodException

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.lang.ClassNotFoundException

java.lang.NoSuchMethodException

getObject

public java.lang.Object 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.

Specified by:

getObject in interface FactoryBean

Returns:

an instance of the bean (should never be null)

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 to check for specific types of beans without instantiating objects, e.g. on autowiring.

For a singleton, this can simply return getObject().getClass(), or even null, as autowiring will always check the actual objects for singletons. For prototypes, returning a meaningful type here is highly advisable, as autowiring will simply ignore them else.

Specified by:

getObjectType in interface FactoryBean

Returns:

the type of object that this FactoryBean creates, or null

ListableBeanFactory.getBeansOfType(java.lang.Class, boolean, boolean)

isSingleton

public boolean isSingleton()

Description copied from interface: FactoryBean

Is the bean managed by this factory a singleton or a prototype? That is, will getObject() always return the same object?

The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory.

Specified by:

isSingleton in interface FactoryBean

Returns:

if this bean is a singleton
