AMQP

The amqp: component supports the AMQP 1.0 protocol using the JMS Client API of the Qpid project. In case you want to use AMQP 0.9 (in particular RabbitMQ) you might also be interested in the Camel RabbitMQ component. Please keep in mind that prior to the Camel 2.17.0 AMQP component supported AMQP 0.9 and above, however since Camel 2.17.0 it supports only AMQP 1.0.

Maven users will need to add the following dependency to their pom.xml for this component:

URI format

AMQP Options

You can specify all of the various configuration options of the JMS component after the destination name.

Usage

As AMQP component inherits from the JMS component. The usage of the former is almost identical to the latter:

Using AMQP component

Configuring AMQP component

Starting from the Camel 2.16.1 you can also use the AMQPComponent#amqp10Component(String connectionURI) factory method to return the AMQP 1.0 component with the pre-configured topic prefix: 

Creating AMQP 1.0 component

Keep in mind that starting from the Camel 2.17 the AMQPComponent#amqp10Component(String connectionURI) factory method has been deprecated on the behalf of the AMQPComponent#amqpComponent(String connectionURI)

Creating AMQP 1.0 component

Starting from Camel 2.17, in order to automatically configure the AMQP component, you can also add an instance of org.apache.camel.component.amqp.AMQPConnectionDetails to the registry. For example for Spring Boot you just have to define bean:

AMQP connection details auto-configuration

 

You can also rely on the Camel properties to read the AMQP connection details. The factory method AMQPConnectionDetails.discoverAMQP() attempts to read Camel properties in a Kubernetes-like convention, just as demonstrated on the snippet below:

 

AMQP connection details auto-configuration

Configuring Connection Factory

Like with any other JMS-based component, usually it's important to configure JMS connection factory. For example, you'd like to set your broker URL or set proper connection credentials. Additionally, you would always want to set some kind of pooling (or caching) on the connection factory. An example of how to do both of these tasks is shown below.

Using amqp inside Karaf

To use the amqp component inside Karaf use the predefined feature called camel-amqp to install the necessary bundles.

Example:

and the environment would be set.

Use the camel-blueprint or camel-spring features to define routes in those contexts.
