A Vert.x client allowing applications to interact with a RabbitMQ broker (AMQP 0.9.1)

This service is experimental and the APIs are likely to change before settling down.

Getting Started

Maven

Add the following dependency to your maven project

<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-rabbitmq-client</artifactId>
  <version>3.3.0.CR2</version>
</dependency>

Gradle

Add the following dependency to your gradle project

dependencies {
  compile 'io.vertx:vertx-rabbitmq-client:3.3.0.CR2'
}

Create a client

You can create a client instance as follows:

import io.vertx.groovy.rabbitmq.RabbitMQClient
def client = RabbitMQClient.create(vertx, config)

Operations

The following are some examples of the operations supported by the RabbitMQService API.

Consult the javadoc/documentation for detailed information on all API methods.

Publish

Publish a message to a queue

def message = [
  body:"Hello RabbitMQ, from Vert.x !"
]
client.basicPublish("", "my.queue", message, { pubResult ->
  if (pubResult.succeeded()) {
    println("Message published !")
  } else {
    pubResult.cause().printStackTrace()
  }
})

Consume

Consume messages from a queue

// Create the event bus handler which messages will be sent to
// Create the event bus handler which messages will be sent to
vertx.eventBus().consumer("my.address", { msg ->
  def json = msg.body()
  println("Got message: ${json.body}")
})

// Setup the link between rabbitmq consumer and event bus address
client.basicConsume("my.queue", "my.address", { consumeResult ->
  if (consumeResult.succeeded()) {
    println("RabbitMQ consumer created !")
  } else {
    consumeResult.cause().printStackTrace()
  }
})

Get

Will get a message from a queue

client.basicGet("my.queue", true, { getResult ->
  if (getResult.succeeded()) {
    def msg = getResult.result()
    println("Got message: ${msg.body}")
  } else {
    getResult.cause().printStackTrace()
  }
})

Consume messages without auto-ack

// Create the event bus handler which messages will be sent to
vertx.eventBus().consumer("my.address", { msg ->
  def json = msg.body()
  println("Got message: ${json.body}")
  // ack
  client.basicAck(json.deliveryTag, false, { asyncResult ->
  })
})

// Setup the link between rabbitmq consumer and event bus address
client.basicConsume("my.queue", "my.address", false, { consumeResult ->
  if (consumeResult.succeeded()) {
    println("RabbitMQ consumer created !")
  } else {
    consumeResult.cause().printStackTrace()
  }
})

Running the tests

You will need to have RabbitMQ installed and running with default ports on localhost for this to work. <a href="mailto:nscavell@redhat.com">Nick Scavelli</a>
