== AWS MQ Component

*Available as of Camel version 2.21*

The EC2 component supports create, run, start, stop and terminate
https://aws.amazon.com/mq/[AWS MQ] instances.

Prerequisites

You must have a valid Amazon Web Services developer account, and be
signed up to use Amazon MQ. More information is available at
https://aws.amazon.com/mq/[Amazon MQ].

### URI Format

[source,java]
-------------------------
aws-mq://label[?options]
-------------------------

You can append query options to the URI in the following format,
?options=value&option2=value&...

### URI Options


// component options: START
The AWS MQ component supports 6 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *configuration* (advanced) | The AWS MQ default configuration |  | MQConfiguration

| *secretKey* (producer) | Amazon AWS Secret Key |  | String
| *region* (producer) | The region in which MQ client needs to work |  | String
| *resolveProperty Placeholders* (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
|===
// component options: END




// endpoint options: START
The AWS MQ endpoint is configured using URI syntax:

----
aws-mq:label
----

with the following path and query parameters:

==== Path Parameters (1 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *label* | *Required* Logical name |  | String
|===

|===
// endpoint options: END
// spring-boot-auto-configure options: START
=== Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

[source,xml]
----
<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-aws-mq-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
----


The component supports 13 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *camel.component.aws-mq.access-key* | Amazon AWS Access Key |  | String
| *camel.component.aws-mq.basic-property-binding* | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | Boolean

| *camel.component.aws-mq.region* | The region in which MQ client needs to work |  | String
| *camel.component.aws-mq.resolve-property-placeholders* | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | Boolean
| *camel.component.aws-mq.secret-key* | Amazon AWS Secret Key |  | String

// spring-boot-auto-configure options: END




Required MQ component options

You have to provide the amazonMqClient in the
Registry or your accessKey and secretKey to access
the https://aws.amazon.com/mq/[Amazon MQ] service.

### Usage

#### Message headers evaluated by the MQ producer

[width="100%",cols="10%,10%,80%",options="header",]
|=======================================================================
|Header |Type |Description

|`CamelAwsMQMaxResults` |`String` |The number of results that must be retrieved from listBrokers operation

|`CamelAwsMQBrokerName` |`String` |The broker name

|`CamelAwsMQOperation` |`String` |The operation we want to perform

|`CamelAwsMQBrokerId` |`String` |The broker id

|`CamelAwsMQBrokerDeploymentMode` |`String` |The deployment mode for the broker in the createBroker operation

|`CamelAwsMQBrokerInstanceType` |`String` |The instance type for the EC2 machine in the createBroker operation

|`CamelAwsMQBrokerEngine` |`String` |The Broker Engine for MQ. Default is ACTIVEMQ

|`CamelAwsMQBrokerEngineVersion` |`String` |The Broker Engine Version for MQ. Currently you can choose between 5.15.6 and 5.15.0 of ACTIVEMQ

|`CamelAwsMQBrokerUsers` |`List<User>` |The list of users for MQ

|`CamelAwsMQBrokerPubliclyAccessible` |`Boolean` |If the MQ instance must be publicly available or not. Default is false.
|=======================================================================

### Automatic detection of AmazonMQ client in registry

From Camel 3.0.0-M3 the component will be able to detect the presence of an AmazonMQ bean into the registry.
If it's the only instance of that type it will be used as client and you won't have to define it as uri parameter.
This may be really useful for smarter configuration of the endpoint.

Dependencies

Maven users will need to add the following dependency to their pom.xml.

*pom.xml*

[source,xml]
---------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-aws-mq</artifactId>
    <version>${camel-version}</version>
</dependency>
---------------------------------------

where `${camel-version}` must be replaced by the actual version of Camel
(2.16 or higher).
