Can I prevent an Ack from being sent with the Grails RabbitMQ plugin?

The Grails RabbitMQ plugin is great, but I can't seem to find any information about what to do when processing a message fails. I would prefer not to send an Ack back to RabbitMQ, but I can't seem to find any information on how to do this using the plugin.

Is it possible to control this with the RabbitMQ plugin for grails, or am I stuck not using the plugin?

Solution

  • The current version of Grails RabbitMQ plugin (0.3.3) do not support manual acknowledge mode.

    Under the hood Grails RabbitMQ plugin use Spring AMQP libraries, so you can always declare your custom SimpleMessageListenerContainer in resources.groovy and implement a listener with manual acks. Check out http://static.springsource.org/spring-amqp/reference/html/#d0e377
