Class ServerEndpointRegistration

java.lang.Object

javax.websocket.server.ServerEndpointConfig.Configurator

org.springframework.web.socket.server.standard.ServerEndpointRegistration

All Implemented Interfaces:

EndpointConfig, ServerEndpointConfig, Aware, BeanFactoryAware

public class ServerEndpointRegistration
extends ServerEndpointConfig.Configurator
implements ServerEndpointConfig, BeanFactoryAware

An implementation of ServerEndpointConfig for use in Spring applications. A ServerEndpointRegistration bean is detected by ServerEndpointExporter and registered with a Java WebSocket runtime at startup.

Class constructors accept a singleton Endpoint instance or an Endpoint specified by type Class. When specified by type, the endpoint will be instantiated and initialized through the Spring ApplicationContext before each client WebSocket connection.

This class also extends ServerEndpointConfig.Configurator to make it easier to override methods for customizing the handshake process.

4.0

Constructor Detail

ServerEndpointRegistration

public ServerEndpointRegistration(String path,
                                  Class<? extends Endpoint> endpointClass)

Create a new ServerEndpointRegistration instance from an javax.websocket.Endpoint class.

Parameters:

path - the endpoint path

endpointClass - the endpoint class

ServerEndpointRegistration

public ServerEndpointRegistration(String path,
                                  Endpoint endpoint)

Create a new ServerEndpointRegistration instance from an javax.websocket.Endpoint instance.

Parameters:

path - the endpoint path

endpoint - the endpoint instance

getConfigurator

public ServerEndpointConfig.Configurator getConfigurator()

Specified by:

getConfigurator in interface ServerEndpointConfig

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Description copied from interface: BeanFactoryAware

Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:

setBeanFactory in interface BeanFactoryAware

Parameters:

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.
