适用于Java的CRM Dynamics Online 2016 Azure SDK接收带有500错误代码的BrokeredMessages

Question

I have a problem with CRM Dynamics Online 2016 Azure SDK for Java. I can connect to Azure Service Bus, I can see queues and message count in queues, but cannot receive messages. Message Id is null and message body contain 500 error

500 The server was unable to process the request; please retry the operation. If the problem persists, please contact your Service Bus administrator and provide the tracking id. TrackingId:acf8a543-33c9-486d-b13b-443823e6c394_G9,TimeStamp:4/13/2016 7:26:22 AM. If the problem persists, please contact your Service Bus administrator and provide the tracking id. TrackingId:acf8a543-33

Is there any working sample on the Internet to solve the problem?

Test code:

@Test
public void readAllExistedMessagesFromAllQueue() {
    try {
        ServiceBusContract serviceBusContract = ServiceBusConfiguration.configureWithConnectionString(null, Configuration.load(), ASB_CONNECTION_STRING).create(ServiceBusContract.class);

        ReceiveMessageOptions opts = ReceiveMessageOptions.DEFAULT;
        opts.setReceiveMode(ReceiveMode.PEEK_LOCK);

        ListQueuesResult result = serviceBusContract.listQueues();
        if (result != null && result.getItems().size() > 0) {
            for (QueueInfo queueInfo : result.getItems()) {
                logger.debug("queu: " + queueInfo.getPath() + " MessageCount: " + queueInfo.getMessageCount());

                for (int i = 0; i < result.getItems().size(); i++) {
                    BrokeredMessage message = serviceBusContract.receiveQueueMessage(queueInfo.getPath(),
                            opts).getValue();
                    if (message == null) {
                        continue;
                    }
                    System.out.print("__________________________________________");
                    System.out.println("MessageID: " + message.getMessageId());
                    System.out.print("From queue: ");
                    byte[] b = new byte[200];
                    String s = null;
                    int numRead = message.getBody().read(b);
                    while (-1 != numRead) {
                        s = new String(b);
                        s = s.trim();
                        System.out.print(s);
                        numRead = message.getBody().read(b);
                    }
                    System.out.println();
                }
            }
        }

    } catch (IOException e) {
        logger.error(e);
    } catch (ServiceException e) {
        logger.error(e);
    }
}

Per my experience, according to the source code and javadocs of Service Bus, the ServiceBusContract is a Java interface, that you can't directly create an instance of the interface ServiceBusContract .

So please try to use the code below from the section Create a queue of the document "How to use Service Bus queues".

Configuration config =
        ServiceBusConfiguration.configureWithSASAuthentication(
                "<your-servicebus-namespace>",
                "RootManageSharedAccessKey",
                "<SAS-key-value>",
                ".servicebus.windows.net"
                );

ServiceBusContract serviceBusContract = ServiceBusService.create(config);

Update

You can find the SharedAccessKeyName & SharedAccessKey in the connection string via click the button below at the bottom of your service bus page.

Then, show the view below and copy the CONNECTION STRING .

The connection string like this below.

Endpoint=sb://<your-servicebus-namespace>.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=<SAS-key-value>

Please copy the correct part of connection string instead of the related part of the code.
