Class VelocityEngineFactoryBean

java.lang.Object
  org.springframework.ui.velocity.VelocityEngineFactory
      org.springframework.ui.velocity.VelocityEngineFactoryBean

All Implemented Interfaces:

FactoryBean, InitializingBean, ResourceLoaderAware

public class VelocityEngineFactoryBean

extends VelocityEngineFactory

implements FactoryBean, InitializingBean, ResourceLoaderAware

Factory bean that configures a VelocityEngine and provides it as bean reference. This bean is intended for any kind of usage of Velocity in application code, e.g. for generating email content. For web views, VelocityConfigurer is used to set up a VelocityEngine for views.

See base class VelocityEngineFactory for configuration details.

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.io.IOException,
                               org.apache.velocity.exception.VelocityException

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.io.IOException

org.apache.velocity.exception.VelocityException

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
