RabbitMq AutorecoveringChannels已在内存中收集,即使它们已在代码中关闭

在我的RabbitMQ RPC应用程序中,每发布一条消息,我就使用一个RabbitMQ连接和通道。因此,一旦消息得到响应,通道就会关闭。非常简单的应用程序。

即使我关闭了通道(我监视了运行时日志并确保所有通道都已关闭),AutorecoveringChannel对象实例仍在内存中收集和增长。我不知道为什么会这样。由于我希望RabbitMQ客户端在关闭通道后会擦除所有数据和通道。

我在Google和其他地方进行了搜索,以了解原因,但是每篇文章都只是在说要关闭它。想出一个主意,请查看此成长对象的VisualVM结果屏幕快照。

这是我在通过网络套接字收到的每条消息中创建频道的方式

 Object                                               instances

 com.rabbitmq.client.impl.recovery.AutorecoveringChannel    249
 com.rabbitmq.client.impl.recovery.RecordedQueue            502
 com.rabbitmq.client.impl.recovery.RecordedQueueBinding     502
 com.rabbitmq.client.impl.recovery.RecoveryAwareChannelN    255

消息回复后,我正在getConsumer()中关闭通道。

    Channel channel = rabbitMqController.getRmqConnection().createChannel();

    //some code

    DefaultConsumer consumer = getConsumer(methodCall, channel, callbackFunction);

    //some code

    channel.basicConsume(replyQueueName, true, consumer);
    channel.basicConsume(statusReplyQueueName, true, consumer);
    channel.basicPublish(WorkerConfig.getInstance().getWorkerExchangeName(), methodCall.getMethod(), true, props,
            methodCall.toJson());

closeChannel就是channel.close()。

如果您能猜出这里发生的一切,请与我分享您的想法。即便是能使我在此记忆问题上走上正确路的小建议,也很受欢迎。
