Question

我正在尝试编写一个java发布程序，将单个消息发送到事件中心。但是，当我尝试执行它时，我得到一个连接中止错误。我正在使用下面链接（azure-eventhubs）和版本0.9.0中指定的maven依赖项。下面是我想要遵循的链接和主要方法。

https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-java-ephcs-getstarted

public static void main(String[] args)
        throws ServiceBusException, ExecutionException, InterruptedException, IOException {
    final String namespaceName = "<namespace name>";
    final String eventHubName = "<created with same name as namespace>";
    final String sasKeyName = "RootManageSharedAccessKey";
    final String sasKey = "<primary key from shared acccess policies>";

    ConnectionStringBuilder connStr = new ConnectionStringBuilder(namespaceName, eventHubName, sasKeyName, sasKey);

    byte[] payloadBytes = "Test AMQP message from JMS, Yaay it works".getBytes("UTF-8");
    EventData sendEvent = new EventData(payloadBytes);

    EventHubClient ehClient = EventHubClient.createFromConnectionStringSync(connStr.toString());
    ehClient.sendSync(sendEvent);
}

这是我得到的错误的堆栈跟踪。任何帮助表示赞赏。

Answer 1

总结上述评论，似乎是issue page评论列表末尾的类似GitHub的Azure EventHub SDK for Java问题。但是，根据我的经验，似乎有些防火墙＆amp;防病毒软件阻止了SSL上的amqp连接。正如@Hemanthmeka所说，这个问题是由他办公室的防火墙造成的。

是的，这绝对是防火墙问题，您需要使用以下代码来帮助您在将数据写入EventHub时解决连接问题。

希望这会有所帮助！

final ConnectionStringBuilder connStr = new ConnectionStringBuilder()
                .setNamespaceName("Your namespace name")
                .setEventHubName("Your eventHub Name")
                .setSasKeyName("Enter the SAS key name")
                .setSasKey("SAS Key details");

        connStr.setTransportType(TransportType.AMQP_WEB_SOCKETS);
        ProxySelector.setDefault(new ProxySelector() {
            @Override
            public List<Proxy> select(URI uri) {
                LinkedList<Proxy> proxies = new LinkedList<>();
                proxies.add(new Proxy(Proxy.Type.HTTP,
                        new InetSocketAddress("proxy information" ,port)));
                return proxies;
            }
            @Override
            public void connectFailed(URI uri, SocketAddress sa, IOException ioe) {
                // trace and follow up on why proxy server is down
            }
        });
