@Deprecated
public class VelocityEngineFactoryBean
extends VelocityEngineFactory
implements FactoryBean<org.apache.velocity.app.VelocityEngine>, 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.

The simplest way to use this class is to specify a "resourceLoaderPath"; you do not need any further configuration then. For example, in a web application context:

 <bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
   <property name="resourceLoaderPath" value="/WEB-INF/velocity/"/>
 </bean>

See the base class VelocityEngineFactory for configuration details.

void	afterPropertiesSet() Deprecated. Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws IOException,
                               org.apache.velocity.exception.VelocityException

Deprecated.

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:

IOException

org.apache.velocity.exception.VelocityException

getObject

public org.apache.velocity.app.VelocityEngine getObject()

Deprecated.

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<org.apache.velocity.app.VelocityEngine>

Returns:

an instance of the bean (can be null)

See Also:

FactoryBeanNotInitializedException

getObjectType

public Class<? extends org.apache.velocity.app.VelocityEngine> getObjectType()

Deprecated.

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<org.apache.velocity.app.VelocityEngine>

Returns:

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

ListableBeanFactory.getBeansOfType(java.lang.Class<T>)

isSingleton

public boolean isSingleton()

Deprecated.

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<org.apache.velocity.app.VelocityEngine>

Returns:

whether the exposed object is a singleton
