How to ack a message from different Channel of RabbitTemplate?

Suppose I have single rabbitTemplate instance, and I call rabbitTemplate.send（Message）to publishe a message to RabbitMQ server.

What I want to do here are: 1. from publisher view , how to make sure the message is received by RabbitMQ ? 2. In the consumer side, I use the same rabbitTemplate to receive message in a thread, and I want to manually ack the message in the other thread.

Is there any way to manually ack the message by RabbitTemplate?

Thank you for any help.

  1. RabbitMQ is asynchronous so there's no way to "wait" for the message to be secured in the broker; you can enable publisher confirms to get confirmation that a message was delivered to a queue. See the documentation for more information.

  2. You can't manually ack the message when using one of the receive*() methods; you would have to drop down to the native API by using the execute() method; in the callback, perform channel.basicGet(queue, false) to receive the message and then channel.basicAck(deliveryTag).
