public class ServletServerContainerFactoryBean extends Object implements FactoryBean<WebSocketContainer>, ServletContextAware, InitializingBean
FactoryBean
for configuring ServerContainer
.
Since there is usually only one ServerContainer
instance accessible under a
well-known javax.servlet.ServletContext
attribute, simply declaring this
FactoryBean and using its setters allows for configuring the ServerContainer
through Spring configuration.
This is useful even if the ServerContainer
is not injected into any other
bean within the Spring application context. For example, an application can configure
a DefaultHandshakeHandler
,
a SockJsService
, or
ServerEndpointExporter
, and separately declare this FactoryBean in order
to customize the properties of the (one and only) ServerContainer
instance.

getObject()
Return an instance (possibly shared or independent) of the object
managed by this factory.

getObjectType()
Return the type of object that this FactoryBean creates,
or
null if not known in advance. |
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)? |

ServletContextAware
ServletContext
that this object runs in.
Invoked after population of normal bean properties but before an init
callback like InitializingBean's afterPropertiesSet
or a
custom init-method. Invoked after ApplicationContextAware's
setApplicationContext
.

InitializingBean
BeanFactory
after it has set all bean properties
and satisfied BeanFactoryAware
, ApplicationContextAware
etc.
This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

@Nullable public ServerContainer 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.

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
.
The default implementation returns true
, since a
FactoryBean
typically manages a singleton instance.
