This tiny lib has only one purpose: simplify the life of the developer when creating a RabbitMQ
Channel. The assumptions are:
- a consumer owns a queue, so it'll need to create a queue and the corresponding binding(s) from one or multiple exchange(s)
- a producer owns an exchange, so it'll need to create an exchange
This library will give you a few methods to do this, whitout any further boilerplate.
val rabbitConfig = RabbitConfig( host = "localhost", vhost = "/", username = "guest", password = "guest" ) val consumingChannel = BunnyChannelFactory(rabbitConfig) .forConsumer( queueName = "q", exchangeName = "e", routingKey = "k" ) val producingChannel = BunnyChannelFactory(rabbitConfig) .forProducer( exchangeName = "e", exchangeType = "topic" ) // your code that use the channels..
For more, take a look at the tests.
The methods that
BunnyChannelFactory offers are:
forConsumer(queueName: String, exchangeName: String, routingKey: String, args: Map[String, AnyRef] = Map()): Try[Channel], which will create a queue and the binding to the exchanges provided.
def forConsumer(queueName: String, bindings: Binding*): Try[Channel], which is like the previous, but with only one exchange.
def forProducer(exchangeName: String, exchangeType: String): Try[ConfirmedChannelContainer], which will create a new exchange in which a producer can push messages. The channel which is returned supports publisher confirms.
def forProducerUnconfirmed(exchangeName: String, exchangeType: String): Try[UnconfirmedChannelContainer], like the previous without the publisher confirms turned on.
- other additional two methods
forProducerUnconfirmedWithQueueBound, which are like the previous but will also create a binding to a queue. One use case for these two are for supporting error queues.
