Java WebSocketClient断开连接的RemoteEndpoint不可用

我正在尝试在线程中实现WebSocketClient，其中客户端持续向服务器发送消息，但我看到异常：

org.eclipse.jetty.websocket.api.WebSocketException:RemoteEndpoint 不可用，当前状态[关闭]，应为[打开或连接]

代码如下：

public class ProcessAnalysisThread extends Thread {

    static String dest = "ws://localhost:8086/Echo/";
    WebSocketClient client;
    EAMClientSocket socket;

    public void run() {
        initializeWSClient();

        while (true) {
            System.out.println("Thread running");
            try {
                Thread.sleep(500);
                socket.sendMessage("echo");
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

    }

    void initializeWSClient() {

        client = new WebSocketClient();
        try {

            socket = new EAMClientSocket(this);
            client.start();
            URI echoUri = new URI(dest);
            System.out.println("URI Resolved");
            ClientUpgradeRequest request = new ClientUpgradeRequest();
            client.connect(socket, echoUri, request);
            System.out.println("Connected and Waiting .....");
            socket.getLatch().await();
            System.out.println("Latched");

            System.out.println("RequestURI: " + request.getRequestURI().toString());

            socket.sendMessage("echo");
            System.out.println("Sent Msg: echo");
            socket.sendMessage("test");
            System.out.println("Sent Msg: test");
//          Thread.sleep(10000l);

        } catch (Throwable t) {
            System.out.println("Exception");
            t.printStackTrace();
        } finally {
            try {
                client.stop();
            } catch (Exception e) {
                System.out.println("Exception1");
                e.printStackTrace();
            }
        }
    }

}

以下是输出：

Connected and Waiting .....

RequestURI: ws://localhost:8086/Echo/
Sent Msg: echo
Sent Msg: test
Message received from server:echo
Message received from server:test

看起来我的线程没有在这里保存套接字引用

您在initializemethod的finally子句中停止了客户端，这是正确的。我很尴尬。尝试了一个示例代码，但错过了finally block。您在initialize method的finally子句中停止了客户端，这是正确的。我很尴尬。尝试了一个示例代码，但最终错过了块
