java.lang.Objectorg.springframework.format.support.FormattingConversionServiceFactoryBean
public class FormattingConversionServiceFactoryBean
A factory for a FormattingConversionService
that installs default
formatters for common types such as numbers and datetimes.
Subclasses may override installFormatters(FormatterRegistry)
to register custom formatters.

Method Summary | |
---|---|
void |
afterPropertiesSet()
Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware). |
FormattingConversionService |
getObject()
Return an instance (possibly shared or independent) of the object managed by this factory. |
Class<? extends FormattingConversionService> |
getObjectType()
Return the type of object that this FactoryBean creates, or null if not known in advance. |
protected void |
installFormatters(FormatterRegistry registry)
Install Formatters and Converters into the new FormattingConversionService using the FormatterRegistry SPI. |
boolean |
isSingleton()
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)? |
void |
setConverters(Set<?> converters)
Configure the set of custom converter objects that should be added: implementing Converter ,
ConverterFactory ,
or GenericConverter . |
void |
setEmbeddedValueResolver(StringValueResolver embeddedValueResolver)
Set the StringValueResolver to use for resolving embedded definition values. |

InitializingBean
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 FormattingConversionService getObject()
FactoryBean
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.

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.

public boolean isSingleton()
FactoryBean
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
.
