如何正确实现SpringWebSocket java客户端

我正在为我的WebSocket服务器开发一个SpringWebSocket Stomp客户端，我得到的信息有冲突。 我已经找到了两种方法来实现它，在不深入太多细节的情况下，我想知道哪种方法被认为是实现客户机的“正确”方法

有人能帮我理解WebSocketConnectionManager的用途吗

还有一个问题，我如何保持websocket连接打开，程序运行以接受新消息，而不必编写System.in.read（）行

第一种方法：直接使用SockJsClient

URI uri = new URI("ws://localhost:8080/stomp");
StandardWebSocketClient simpleWebSocketClient = new StandardWebSocketClient();

List<Transport> transports = new ArrayList<>(1);
transports.add(new WebSocketTransport(simpleWebSocketClient));

SockJsClient sockJsClient = new SockJsClient(transports);
sockJsClient.setMessageCodec(new Jackson2SockJsMessageCodec());

StompMessageReceiver messageHandler = new StompMessageReceiver();
StompWebSocketHandler websocketHandler = new StompWebSocketHandler(messageHandler, new StringMessageConverter());

try {
    this.webSocketClient.doHandshake(websocketHandler, null, uri).get();
} catch (InterruptedException | ExecutionException e) {
    throw new IllegalStateException(e);
}

System.in.read();

如果有意思的话，Spring集成为提供了一个实现

是的，它在内部使用

ConnectionManagerSupport

下面是一个示例，演示如何从

@Configuration

配置它

但我认为您应该尝试使用现成的

WebSocketHandler

实现-

subtocolwebsockethandler

，以及

stompsubtocolhandler

StandardWebSocketClient simpleWebSocketClient = new StandardWebSocketClient();
List<Transport> transports = new ArrayList<>(1);
transports.add(new WebSocketTransport(simpleWebSocketClient));

SockJsClient sockJsClient = new SockJsClient(transports);
sockJsClient.setMessageCodec(new Jackson2SockJsMessageCodec());

StompMessageHandler messageHandler = new StompMessageHandler();
StompWebSocketHandler websocketHandler = new StompWebSocketHandler(messageHandler, new StringMessageConverter());

WebSocketConnectionManager manager = new WebSocketConnectionManager(sockJsClient, websocketHandler, "ws://localhost:8080/stomp");

manager.start();

System.in.read();
