我试图连接我的AMQP 1.0消费者(使用Apache ProtonJ 2库)。但我的连接失败,错误如下

org.apache.qpid.protonj2.client.exceptions.ClientSessionRemotelyClosedException: PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'test_queue_durable' in vhost '/': received 'false' but current is 'true' [condition = amqp:precondition-failed]

下面是我的示例代码。

public void connectAmqp() throws Throwable {
    final String serverHost = "localhost";
    final int serverPort = 5672;
    final String address = "test_queue_durable";
    final Client client = Client.create();

    final ConnectionOptions options = new ConnectionOptions().user("admin").password("admin");

    try{
        Connection connection = client.connect(serverHost, serverPort, options);
        
        Receiver receiver = connection.openReceiver(address);
        
        for (int i = 0; i < 100; ++i) {
            Delivery delivery = receiver.receive();
            System.out.println(delivery.message().body().getClass());
            System.out.println("*-*-*-*          " + new String((byte[])delivery.message().body()));
        }
    }catch (Exception e) {
        e.printStackTrace();
    }
}


注意事项:
1.在RabbitMQ中预先声明队列
1.队列被配置为持久的,以防止消息丢失
1.如果删除队列的持久属性,则使用者连接成功(但这不是预期的)
1.连接需要AMQP 1.0协议
1.用于连接的客户端库是Apache Qpid Proton J2。

已编辑的决议

public void connectAmqp() throws Throwable {
    final String serverHost = "localhost";
    final int serverPort = 5672;
    final String address = "test_queue_durable";
    final Client client = Client.create();

    try{
        ConnectionOptions options = new ConnectionOptions().user("user").password("pa$$w0rd");
        Connection connection = client.connect(serverHost, serverPort, options);
        /**
         * Consumer Connecting to Durable Queue Connections
         * Set durable property on source link of receiveroptions
         */
        ReceiverOptions ro = new ReceiverOptions();
        ro.sourceOptions().durabilityMode(DurabilityMode.CONFIGURATION);
        
        Receiver receiver = connection.openReceiver(address, ro);
        
        for (int i = 0; i < 100; ++i) {
            Delivery delivery = receiver.receive();
            System.out.println(delivery.message().body().getClass());
            System.out.println("*-*-*-*          " + new String((byte[])delivery.message().body()));
        }
    }catch (Exception e) {
        e.printStackTrace();
    }
}

您可能需要配置Receiver Source值以匹配您在代理中创建的队列,以便它允许接收器附加。
你需要做这样的事情(配置满足RabbitMQ附加先决条件):

ReceiverOptions receiverOptions = new ReceiverOptions();
receiverOptions.sourceOptions().durabilityMode(DurabilityMode.CONFIGURATION);

Receiver receiver = session.openReceiver(address, receiverOptions);
