从Java / Spring中检索RabbitMQ队列中未确认消息的数量 [英] Retrieving number of unacknowledged messages in RabbitMQ queue from Java/ Spring

问题描述

有没有办法返回未确认的消息数？

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

我正在使用此代码获取队列中的消息数：

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

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

但我也想知道未确认消息的数量。

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

我看到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），我想必须有一种方法从Java /中检索它春天。

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.

谢谢

更新

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。

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

有可能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：

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

http：// www。 rabbitmq.com/management.html

推荐答案

正如您在更新中所述，如果您启用了管理插件，你可以查询其余的api：

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

例如：

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

这会返回json（除其他外）

This returns json with (among other things)

• messages_unacknowledged


• messages_ready

如果您有到服务器的安全路线，这是件好事。

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