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() {
		JettyRequestUpgradeStrategy strategy = new JettyRequestUpgradeStrategy();
		strategy.addWebSocketConfigurer(configurable -> {
				policy.setInputBufferSize(4 * 8192);
				policy.setIdleTimeout(600000);
		});
		return new DefaultHandshakeHandler(strategy);
	}
}

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);
	}

}
