public class FilterDefinitionFactoryBean extends Object implements FactoryBean<FilterDefinition>, BeanNameAware, InitializingBean
Typically defined as an inner bean within a LocalSessionFactoryBean definition, as the list element for the "filterDefinitions" bean property. For example:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> ... <property name="filterDefinitions"> <list> <bean class="org.springframework.orm.hibernate3.FilterDefinitionFactoryBean"> <property name="filterName" value="myFilter"/> <property name="parameterTypes"> <map> <entry key="myParam" value="string"/> <entry key="myOtherParam" value="long"/> </map> </property> </bean> </list> </property> ... </bean>Alternatively, specify a bean id (or name) attribute for the inner bean, instead of the "filterName" property.

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).
Return an instance (possibly shared or independent) of the object managed by this factory.
Return the type of object that this FactoryBean creates, or

If no explicit filter name has been specified, the bean name of the FilterDefinitionFactoryBean will be used.
Specify a default filter condition for the filter, if any.
Set the name of the filter.
Set the parameter types for the filter, with parameter names as keys and type names as values.

name- 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.
public void afterPropertiesSet()
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.
public FilterDefinition getObject()
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
As of Spring 2.0, FactoryBeans are allowed to return
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.
public Class<FilterDefinition> getObjectType()
nullif 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.

public boolean isSingleton()
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
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

An implementation of the extended
may explicitly indicate independent instances through its
SmartFactoryBean.isPrototype() method. Plain
implementations which do not implement this extended interface are
simply assumed to always return independent instances if the
isSingleton() implementation returns
