从Java / Spring中检索RabbitMQ队列中未确认消息的数量

is there any way to return the number of messages that are unacknowledged?

有没有办法返回未确认的消息数?

I am using this code to get the number of messages in the queue:

我使用此代码来获取队列中的消息数:

DeclareOk declareOk = amqpAdmin.getRabbitTemplate().execute(
        new ChannelCallback<DeclareOk>() {
            public DeclareOk doInRabbit(Channel channel)
                throws Exception {
                return channel.queueDeclarePassive(name);
            }
        });
return declareOk.getMessageCount();

but I would like to know as well the number of unacknowledged messages.

但我想知道未确认消息的数量。

I have seen that the RabbitMQ Admin tool includes that information (for each queue it gives out the number of Ready/ Unacked and Total messages) and I guess there must be a way to retrieve that from Java/ Spring.

我已经看到RabbitMQ管理工具包含了这些信息(对于每个队列,它给出了Ready / Unacked和Total消息的数量),我想必须有一种从Java / Spring中检索它的方法。

Thanks

UPDATE

Oks, it seems there is no way to accomplish that programmatically since listing of configuration/ queues is not part of AMPQ.

Oks,似乎没有办法以编程方式完成,因为配置/队列的列表不是AMPQ的一部分。

There is the possibility to enable the management plugin and query the REST web services about the queues (among other things). More info here:

可以启用管理插件并查询有关队列的REST Web服务(以及其他内容)。更多信息:

As you say in your update, if you enable the management plugin, you can query the rest api:

正如您在更新中所说,如果启用管理插件,您可以查询其余的api:

Eg:

`http://username:password@queue-server:15672/api/queues/%2f/queue_name.queue`

This returns json with (among other things)

这会返回json(除其他外)

messages_unacknowledged
messages_ready

It's good stuff if you have a safe route to the server.

如果你有一条通往服务器的安全路线,这是件好事。
