Question

我正在尝试websocket应用程序。作为服务器，我使用Glassfish，工作良好，但我有一个问题与websocket。

当我运行html与javascript在控制台是错误404

在src/main/java/websockets中有I WebSocketServer.java

    throws IOException, InterruptedException {
        // Print the client message for testing purposes
        System.out.println("Received: " + message);
        // Send the first message to the client
        session.getBasicRemote().sendText("This is the first server message");
        // Send 3 messages to the client every 5 seconds
        int sentMessages = 0;
        while(sentMessages < 3){
            Thread.sleep(5000);
            session.getBasicRemote().
            sendText("This is an intermediate server message. Count: "
                     + sentMessages);
            sentMessages++;
        }
        // Send a final message to the client
        session.getBasicRemote().sendText("This is the last server message");
    }
    @OnOpen
    public void onOpen () {
        System.out.println("Client connected");
    }
    @OnClose
    public void onClose () {
        System.out.println("Connection closed");
    }
    @OnError
    public void onError(Session aclientSession, Throwable aThrowable) {
        System.out.println("Error : " + aclientSession); System.out.println("Error :" + aThrowable);
    }
}

Gradle编译没有错误。当我运行应用程序在http://192.168.37.10:8080/web/page.html(流浪虚拟机)

抛出错误

WebSocket连接到'ws://localhost:8080/web/WebSocket '失败:WebSocket握手时错误:意外响应码:404

在glassfish中添加应用程序在上下文根:web

怎么了?你能帮我吗?请。谢谢:)

Answer 1

应该将ServerEndPoint设置为一个值。ServerEndPoint (value = "/websocket")

Answer 2

添加以下选项后即可正常工作:

atmosphere.addInitParameter(ApplicationConfig.PROPERTY_NATIVE_COMETSUPPORT, "true");
atmosphere.addInitParameter(ApplicationConfig.WEBSOCKET_SUPPRESS_JSR356, "true");

或在web.xml中:

<init-param>
    <param-name>org.atmosphere.useNative</param-name>
    <param-value>true</param-value>
</init-param>
