WebSocket Server

要配置底层 WebSocket 服务器，服务器配置中 的信息适用。然而，对于 Jetty，你需要通过 StompEndpointRegistry 设置 HandshakeHandler 和 WebSocketPolicy。

@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)));
    }
}
