如何将Azure Service Bus与Qpid Proton Java连接？

Question

我需要连接Azure服务总线来发送消息。我按照给定的示例，仅将主机名更改为

amqps://XXX:[email protected]/queueName

运行 Send 类时，出现以下错误。我尝试了很多但无法解决问题。

线程“main”中的异常 org.apache.qpid.proton.engine.HandlerException： java.lang.IllegalStateException：没有为连接提供地址 在 org.apache.qpid.proton.engine.impl.EventImpl.dispatch(EventImpl.java:112) 在 org.apache.qpid.proton.reactor.impl.ReactorImpl.dispatch(ReactorImpl.java:324) 在 org.apache.qpid.proton.reactor.impl.ReactorImpl.process(ReactorImpl.java:292) 在 org.apache.qpid.proton.reactor.impl.ReactorImpl.run(ReactorImpl.java:357) 在 org.apache.qpid.proton.example.reactor.Send.main(Send.java:151) 导致：java.lang.IllegalStateException：没有提供地址 连接于 org.apache.qpid.proton.reactor.impl.IOHandler.handleBound(IOHandler.java:155) 在 org.apache.qpid.proton.reactor.impl.IOHandler.onUnhandled(IOHandler.java:380) 在 org.apache.qpid.proton.engine.BaseHandler.onConnectionBound(BaseHandler.java:58) 在 org.apache.qpid.proton.engine.BaseHandler.handle(BaseHandler.java:131) 在 org.apache.qpid.proton.engine.impl.EventImpl.dispatch(EventImpl.java:108) ...还有4个

有点晚了，对于图书馆的更现代版本，但我自己很难找到这个答案。请参阅下面的基本示例，该示例从今天起可与 Qpid Proton-J2 一起使用，该示例源自此处的示例代码。

package com;
import org.apache.qpid.protonj2.client.Client;
import org.apache.qpid.protonj2.client.Connection;
import org.apache.qpid.protonj2.client.ConnectionOptions;
import org.apache.qpid.protonj2.client.Delivery;
import org.apache.qpid.protonj2.client.Message;
import org.apache.qpid.protonj2.client.Receiver;
import org.apache.qpid.protonj2.client.Sender;
import org.apache.qpid.protonj2.client.exceptions.ClientException;

public class Test {

    public static void main(String[] args) throws ClientException {
        final String serverHost = System.getProperty("HOST", "YOUR_SERVICEBUS_NAMESPACE_HERE.servicebus.windows.net");
        final int serverPort = Integer.getInteger("PORT", 5671);
        final String address = System.getProperty("ADDRESS", "YOUR_QUEUE_NAME_HERE");

        final Client client = Client.create();

        final ConnectionOptions options = new ConnectionOptions();
        options.sslOptions().sslEnabled(true);
        options.user("RootManageSharedAccessKey");
        options.password("YOUR_SHARED_ACCESS_KEY_HERE");

        Connection connection = client.connect(serverHost, serverPort, options);
        Sender sender = connection.openSender(address);
        sender.send(Message.create("Hello World"));

        Receiver receiver = connection.openReceiver(address);
        Delivery delivery = receiver.receive();
        Message<String> received = delivery.message();
        System.out.println("Received message with body: " + received.body().toString());
    }
}
