Jetty WebSockets的Jar / Class问题

标签： java websocket jetty embedded-jetty

我遇到了WebSockets的问题。使用Jetty 9.1.0和Maven由Java开发环境IntelliJ IDEA Community Edition 12.1.6执行。 我创建了两个类（下面的代码）。 WsHandler班级：

public class WsHandler extends WebSocketHandler {
private final ConcurrentMap<String, Set<EventWebSocket>> eventsSubscribers = new ConcurrentHashMap<>();

@Override
public WebSocket doWebSocketConnect(HttpServletRequest request, String protocol) {
    return new EventWebSocket();
}

private void fireEvent(String eventName) {
    Set<EventWebSocket> subscribers = eventsSubscribers.get(eventName);
    System.out.println("Event " + eventName + " was occurred. Subscribers " + subscribers);
    if (subscribers != null) {
        for (EventWebSocket webSocket : subscribers) {
            webSocket.onEvent(eventName);
        }
    }
}

public final class EventWebSocket implements WebSocket.OnTextMessage {

    private Connection connection;
    private List<String> subscribedEvents = new LinkedList();

    @Override
    public void onOpen(Connection connection) {
        System.out.println("Open connection " + connection);
        this.connection = connection;
    }

    @Override
    public void onMessage(String data) {
        System.out.println("Process msg: " + data);
        if (data.isEmpty()) return;
        if (data.startsWith("Sub")) { // subscribe
            if (data.length() < 5) return;
            String eventName = data.split(":")[1]; // subscribing message format "Sub:EventName"
            Set<EventWebSocket> subscribers = eventsSubscribers.get(eventName);
            // double-check idiom for lazy initialization
            if (subscribers == null) {
                synchronized (EventHandler.class) {
                    if (eventsSubscribers.get(eventName) == null) {
                        subscribers = new CopyOnWriteArraySet<>();
                        eventsSubscribers.putIfAbsent(eventName, subscribers);
                    }
                }
            }
            subscribers.add(this);
            subscribedEvents.add(eventName);
        } else if (data.startsWith("Fire")) { // fire event
            if (data.length() < 6) return;
            String eventName = data.split(":")[1]; // Fire event message format "Fire:EventName"
            fireEvent(eventName);
        } else {
            try {
                connection.sendMessage("Unknown command: " + data);
            } catch (IOException ex) {
                System.err.println("Ooops: " + ex + ". Close connection " + connection);
            }
        }
    }

    public void onEvent(String eventName) {
        try {
            connection.sendMessage("Event " + eventName + " was occurred");
        } catch (IOException ex) {
            System.err.println("Ooops: " + ex + ". Close connection " + connection);
        }
    }

    @Override
    public void onClose(int closeCode, String message) {
        System.out.println("Close connection " + connection);
        // remove from subscribers
        for (String eventName : subscribedEvents) {
            eventsSubscribers.get(eventName).remove(this);
        }
    }
}}

Class SimpleEchoClien：

public class SimpleEchoClient {

public static void main(String[] args) throws Exception {

    Server server = new Server(8080);
    WsHandler handler = new WsHandler();
    server.setHandler(handler);
    server.start();
    server.join();
}}

运行并获取错误：

您的计划的第一行输出

2013-12-01 00:52:53.727:INFO:oejs.Server:main: jetty-9.1.0.M0

你需要处理多件事。

  1. 您正在运行Jetty的混合版本。您的码头腹部空间位于7.4.4.v20110707，而Jetty的其余部分位于9.1.0.M0。
  2. 您应该升级到Jetty 9.1的最终（非里程碑，非发布候选版本）版本，以获得最成熟的websocket实现。那将是码头9.1.0.v20131115
  3. 您的代码示例适用于websocket的早期草案实现，并显示您正在查看一些非常古老的代码示例。会阻止你使用那个已经弃用的API。
  4. 您的Java版本已经过时了。 1.7更新17在6月份过期（是的，Java版本到期。请阅读发行说明。例如：u40 expires on 12/10/2013和u45 expires on 1/14/2014）
  5. 使用 Modern Jetty WebSocket API 或 javax.websocket标准API 。

    6. Modern Jetty WebSocket API

    示例项目已在以下位置设置：

    https://github.com/jetty-project/embedded-jetty-websocket-examples/tree/master/native-jetty-websocket-example

    您需要的maven依赖项：

    <!-- To write basic websockets against -->
<dependency>
  <groupId>org.eclipse.jetty.websocket</groupId>
  <artifactId>websocket-api</artifactId>
  <version>9.1.0.v20131115</version>
</dependency>
<!-- To run websockets in embedded server -->
<dependency>
  <groupId>org.eclipse.jetty.websocket</groupId>
  <artifactId>websocket-server</artifactId>
  <version>9.1.0.v20131115</version>
</dependency>
<!-- To run websockets client -->
<dependency>
  <groupId>org.eclipse.jetty.websocket</groupId>
  <artifactId>websocket-client</artifactId>
  <version>9.1.0.v20131115</version>
</dependency>

    查看示例代码。

    • EventServer.java - 这是jetty嵌入式服务器代码，用于初始化处理程序树+ ServletContext。它将EventServlet映射到"/events/*"
      • 的路径规范
    • EventServlet.java - 这只是将EventSocket注册到Servlet（对于后台，WebSocketServletFactory有一个简单的默认实现WebSocketCreator，只支持1个websocket。.register(Class<?>) call只是告诉这个默认的WebSocketCreator要创建的WebSocket。如果你想要一个更复杂的WebSocketCreator，那么你可以使用自己的实现来调用WebSocketServletFactory.setCreator(WebSocketCreator)。
    • EventSocket.java - 接收传入事件的实际websocket
    • EventClient.java - 因为您的演示代码被称为客户端，但其中包含服务器代码，我真的不知道您的计划是什么，所以我也投入了Native Jetty WebSocket客户端示例。

    Jetty上的javax.websocket标准API

    示例项目已在以下位置设置：

    https://github.com/jetty-project/embedded-jetty-websocket-examples/tree/master/javax.websocket-example

    您需要的maven依赖项：

    <!-- To write basic javax.websocket against -->
<dependency>
  <groupId>javax.websocket</groupId>
  <artifactId>javax.websocket-api</artifactId>
  <version>1.0</version>
</dependency>
<!-- To run javax.websocket in embedded server -->
<dependency>
  <groupId>org.eclipse.jetty.websocket</groupId>
  <artifactId>javax-websocket-server-impl</artifactId>
  <version>9.1.0.v20131115</version>
</dependency>
<!-- To run javax.websocket client -->
<dependency>
  <groupId>org.eclipse.jetty.websocket</groupId>
  <artifactId>javax-websocket-client-impl</artifactId>
  <version>9.1.0.v20131115</version>
</dependency>

    查看示例代码。

    • EventServer.java - 这与Native API略有不同，因为javax.websocket世界中的所有内容都基于带有发现的Annotations。所以这个嵌入式服务器建立了一个ServletContextHandler，然后通过调用WebSocketServerContainerInitializer.configureContext(context)来初始化javax.websocket层，最后用addEndpoint(Class)对ServerContainer进行手动EventSocket.java。
    • EventClient.java - 使用javax.websocket的注释，此类都注释为Server端点和Client端点，应该接收各种事件的方法也会注释以指示其所需的目的。< / LI>
    • WebSocketContainer - 这使用javax.websocket {{3}}（客户端容器）连接到服务器并发送消息。 （特别值得注意的是，清理WebSocketContainer生命周期的额外工作。来自JSR-356规范的缺失功能）
    祝你好运
