A FactoryBean for configuring jakarta.websocket.server.ServerContainer. Since there is usually only one ServerContainer instance accessible under a well-known jakarta.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 org.springframework.web.socket.server.support.DefaultHandshakeHandler, a org.springframework.web.socket.sockjs.SockJsService, or ServerEndpointExporter, and separately declare this FactoryBean in order to customize the properties of the (one and only) ServerContainer instance.

public void
afterPropertiesSet()

Implements org.springframework.beans.factory.InitializingBean.afterPropertiesSet.

Invoked by the containing 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.

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

public Class<?>
getObjectType()

Implements org.springframework.beans.factory.FactoryBean.getObjectType.

Return the type of object that this FactoryBean creates, or null if not known in advance.

public boolean
isSingleton()

Overrides default org.springframework.beans.factory.FactoryBean.isSingleton.

Is the object managed by this factory a singleton?

public ServerContainer getObject()

Implements org.springframework.beans.factory.FactoryBean.getObject.

Doc from org.springframework.beans.factory.FactoryBean.getObject.

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.

Returns:ServerContainer

an instance of the bean (can be null)

public Class<?> getObjectType()

Implements org.springframework.beans.factory.FactoryBean.getObjectType.

Doc from org.springframework.beans.factory.FactoryBean.getObjectType.

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.

Returns:Class<?>

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

@Override
isSingletonback to summary
public boolean isSingleton()

Overrides default org.springframework.beans.factory.FactoryBean.isSingleton.

Doc from org.springframework.beans.factory.FactoryBean.isSingleton.

Is the object managed by this factory a singleton? That is, will 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.

Returns:boolean

whether the exposed object is a singleton
