Java WebSockets：关闭websocket连接时不调用OnClose方法

时间：2014-07-12 21:17:45

标签： java javascript jboss websocket

这是我的WebSocket端点

import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.twitter.hbc.core.Client;

@ServerEndpoint("/tweets")
public class TweetStreamServer {
    private static final Logger LOGGER = LoggerFactory.getLogger(TweetStreamServer.class);

    @OnMessage
    public void tweets(final String message, final Session client) throws IOException, InterruptedException {

        LOGGER.debug("registering search term {}", message);
        final TwitterHoseBird twitterHoseBird = new TwitterHoseBird();
        final Client twitterClient = twitterHoseBird.getInstance(message);
        while(!twitterClient.isDone()) {
            client.getAsyncRemote().sendText(twitterHoseBird.getMsgQueue().take());
        }
    }

    @OnClose
    public void onClose(CloseReason reason) {
        System.out.println("Closing connection");
        LOGGER.warn("closing connection {}", reason);
    }
}

当我部署它时，我尝试通过JavaScript代码

命中端点 
var connection = new WebSocket('ws://127.0.0.1:8080/tweetstream-1.0-SNAPSHOT/tweets');
connection.onmessage = function (e) {
  console.log('Server: ' + e.data);
};
connection.send('fifa');

这开始从服务器发送推文。现在，当我关闭客户端的连接时，我会

connection.close();

问题吗
我想在websocket客户端连接关闭后关闭与twitter的连接。我希望执行以下代码

@OnClose
public void onClose(CloseReason reason) {
    System.out.println("Closing connection");
    LOGGER.warn("closing connection {}", reason);
}

但在服务器日志中，我没有看到任何此类声明

我在这里缺少什么？

更新
我测试如下

    @Test
    public void test() throws URISyntaxException, IOException, DeploymentException, InterruptedException {
        System.out.println("URI: " + getEndpointUrl());
        TweetStreamClient.latch = new CountDownLatch(1);
        Session session = connectToServer(TweetStreamClient.class, "tweets");
        assertNotNull(session);
        // (todo: harit) assert correct things
//        assertTrue(TweetStreamClient.latch.await(10, TimeUnit.SECONDS));
//        assertEquals("Hello", TweetStreamClient.response);
    }

当我运行此测试时，我会在日志中看到以下内容

8295 [main] INFO io.undertow.websockets.jsr - UT026004: Adding annotated client endpoint class com.self.tweetstream.TweetStreamClient
14:59:26,981 INFO  [org.wildfly.extension.undertow] (MSC service thread 1-13) JBAS017535: Unregistered web context: /b5b7b561-8b49-4c69-b55f-7859b86da36d

但是当我从JavaScript调用connection.close()时，我看不到这样的事情

1 个答案:

答案 0 :(得分：1)

我遇到了同样的问题，最初认为这是一个Wildfly问题，但后来注意到Firefox正在触发@OnClose。当我添加@OnError时，Chromium正在触发它。

我发现another StackOverflow question指的是相同的行为。

一个月前，Chromium似乎只有fixed this issue。
