WebSocket Transport
This section explains how to configure the underlying WebSocket server transport.
For Jakarta WebSocket servers, add a ServletServerContainerFactoryBean
to your
configuration. For examples, see
Configuring the Server
under the WebSocket section.
For Jetty WebSocket servers, customize the JettyRequestUpgradeStrategy
as follows:
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/portfolio").setHandshakeHandler(handshakeHandler());
}
@Bean
public DefaultHandshakeHandler handshakeHandler() {
WebSocketPolicy policy = new WebSocketPolicy(WebSocketBehavior.SERVER);
policy.setInputBufferSize(8192);
policy.setIdleTimeout(600000);
return new DefaultHandshakeHandler(
new JettyRequestUpgradeStrategy(new WebSocketServerFactory(policy)));
}
}
In addition to WebSocket server properties, there are also STOMP WebSocket transport properties to customize as follows:
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registry) {
registry.setMessageSizeLimit(4 * 8192);
registry.setTimeToFirstMessage(30000);
}
}
