我需要将我的消息从azure主题订阅发送到死信队列，以防在读取和处理来自主题的消息时出错。所以我试着直接将消息推送到dlq。
我的示例代码如下

static void sendMessage()
{
    // create a Service Bus Sender client for the queue 
    ServiceBusSenderClient senderClient = new ServiceBusClientBuilder()
            .connectionString(connectionString)
            .sender()
            .topicName(topicName)

            .buildClient();

    // send one message to the topic

    senderClient.sendMessage(new ServiceBusMessage("Hello, World!"));    

}
static void resceiveAsync() {
    ServiceBusReceiverAsyncClient receiver = new ServiceBusClientBuilder()
            .connectionString(connectionString)
            .receiver()
            .topicName(topicName)
            .subscriptionName(subName)
            .buildAsyncClient();

        // receive() operation continuously fetches messages until the subscription is disposed.
        // The stream is infinite, and completes when the subscription or receiver is closed.
        Disposable subscription = receiver.receiveMessages().subscribe(message -> {

            System.out.printf("Id: %s%n", message.getMessageId());
            System.out.printf("Contents: %s%n", message.getBody().toString());
        }, error -> {
                System.err.println("Error occurred while receiving messages: " + error);
            }, () -> {
                System.out.println("Finished receiving messages.");
            });

        // Continue application processing. When you are finished receiving messages, dispose of the subscription.
        subscription.dispose();

        // When you are done using the receiver, dispose of it.
        receiver.close();

}

我尝试获取死信队列路径

String dlq = EntityNameHelper.formatDeadLetterPath(topicName);

我得到了死信队列的路径，比如=“mytopic/$deadletterqueue”
但它在传递路径作为主题名时不起作用。它引发实体主题找不到异常。
有谁能告诉我这件事吗
