Create a standalone Java websocket client endpoint?
提问by Tyler Durden
I want to create a websocket endpoint clientin Java (as pure as possible, no frameworks), but virtually all the examples I have found have only server endpoints in Java, whereas the client is in Javascript. Can anyone point me to a good client example, or provide one?
我想用 Java创建一个 websocket 端点客户端（尽可能纯，没有框架），但几乎我发现的所有示例都只有 Java 中的服务器端点，而客户端是 Javascript。谁能给我指出一个好的客户例子，或者提供一个？

Not sure if this fits your criteria, but Jetty has a pretty clean client example here:
不确定这是否符合您的标准，但 Jetty 在这里有一个非常干净的客户端示例：

Hope that helps :)

@ClientEndpointannottation is part of the spec, so I'd suggest to use that,
here is a good tutorial , see step 4 and 6 .
@ClientEndpoint注释是规范的一部分，所以我建议使用它，这是一个很好的教程，请参阅步骤 4 和 6。
Step 6 from Openshift tutorial
Openshift 教程中的第 6 步
@ClientEndpoint
public class WordgameClientEndpoint {
private static CountDownLatch latch;
private Logger logger = Logger.getLogger(this.getClass().getName());
@OnOpen
public void onOpen(Session session) {
// same as above
}
@OnMessage
public String onMessage(String message, Session session) {
// same as above
}
@OnClose
public void onClose(Session session, CloseReason closeReason) {
logger.info(String.format("Session %s close because of %s", session.getId(), closeReason));
latch.countDown();
}
public static void main(String[] args) {
latch = new CountDownLatch(1);
ClientManager client = ClientManager.createClient();
try {
client.connectToServer(WordgameClientEndpoint.class, new URI("ws://localhost:8025/websockets/game"));
latch.await();
} catch (DeploymentException | URISyntaxException | InterruptedException e) {
throw new RuntimeException(e);
}
}
}
}
in this example they are using tyrus, which is the reference implementation for websockets in java, so I think that meets your requirement of a well backed websocket implementation.
在这个例子中，他们使用tyrus，它是 java 中 websockets 的参考实现，所以我认为这满足了你对一个有良好支持的 websocket 实现的要求。
