問題描述

有沒有辦法返回未確認的消息數量?

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

我正在使用此代碼來獲取隊列中的消息數:

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();

但我也想知道未確認消息的數量.

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

我已經看到 RabbitMQ 管理工具包含該信息(對于每個隊列，它給出了 Ready/Unacked 和 Total 消息的數量)，我想一定有一種方法可以從 Java/Spring 中檢索這些信息.

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.

謝謝

更新

好吧，似乎沒有辦法以編程方式完成，因為配置/隊列列表不是 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.

可以啟用管理插件并查詢有關隊列的 REST Web 服務(除其他外).更多信息在這里:

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

推薦答案

如你更新中所說，如果開啟管理插件，可以查詢其余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`

這會返回帶有(除其他外)的 json

This returns json with (among other things)

• messages_unacknowledged
• messages_ready

如果您有一條通往服務器的安全路線，那就太好了.

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