      extended byorg.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 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
See Also:
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
