我有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类：
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);
}
}
}}
SimpleEchoClien类：
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：

你有很多事情需要照顾.
>您正在运行Jetty的混合版本.您的码头腹围位于7.4.4.v20110707,而Jetty的其余部分位于9.1.0.M0.
>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
>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.
>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.阅读发行说明.例如：u40 expires on 12/10/2013和u45 expires on 1/14/2014)
>使用Modern Jetty WebSocket API或javax.websocket标准API.
Modern Jetty WebSocket API
示例项目已设置为：
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映射到路径规范“/ events / *”
> EventServlet.java – 这只是简单地将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<？>)调用只是告诉这个默认的WebSocketCreator创建什么WebSocket如果你想要一个更复杂的WebSocketCreator,你可以用你自己的实现调用WebSocketServletFactory.setCreator(WebSocketCreator))
> EventSocket.java – 接收传入事件的实际websocket
> EventClient.java – 由于您的演示代码被称为客户端,但其中包含服务器代码,我并不真正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
示例项目已设置为：
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.因此,这个嵌入式服务器建立了一个ServletContextHandler,然后通过调用WebSocketServerContainerInitializer.configureContext(context)初始化javax.websocket层,最后使用ServerContainer的手册addEndpoint(Class).
> EventSocket.java – 使用javax.websocket的注释,此类都注释为服务器端点和客户端端点,应该接收各种事件的方法也会注释以指示其所需的目的.
> EventClient.java – 这使用javax.websocket WebSocketContainer(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)
祝好运
