解决:Rabbitmq 消息队列阻塞的问题_rabbitmq 发送消息阻塞

接收消息的正确代码

 
    /**
     * 接收消息
     */
    override fun receiveMessage(queue: String, onMessageReceiveListener: OnMessageReceiveListener) {
        if (!ensureChannelOpen()) return
        try {
            val consumer = object : DefaultConsumer(mChannel) {
                override fun handleDelivery(consumerTag: String?, envelope: Envelope?, properties: AMQP.BasicProperties?, body: ByteArray?) {
                    if (body != null) {
                        onMessageReceiveListener.receivedMessage(String(body, Charsets.UTF_8))
                        mChannel?.basicAck(envelope?.deliveryTag ?: 0L, false)
                    }
                }
            }
            mChannel?.basicConsume(queue, false,"xtsf_"+DataHelper.getUserId(), consumer)
        } catch (e: Exception) {
            Log.d(TAG, Log.getStackTraceString(e))
        }
    }

这里之前一直是收到消息但是basicAck调用之后没有让服务器删消息  原因就是  basicConsume,方法的第三个参数必须设值

而且最好是每个消费者不同,否则,就算调用basicAck也没用,服务器不会删消息
