Class ServerEndpointRegistration

java.lang.Object

javax.websocket.server.ServerEndpointConfig.Configurator

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

All Implemented Interfaces:

javax.websocket.EndpointConfig, javax.websocket.server.ServerEndpointConfig, Aware, BeanFactoryAware

public class ServerEndpointRegistration
extends javax.websocket.server.ServerEndpointConfig.Configurator
implements javax.websocket.server.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.
