[[aws-mq-component]]
= AWS MQ Component

*Available as of Camel version 2.21*

The MQ component supports create, run, start, stop and terminate
https://aws.amazon.com/amazon-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/amazon-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 5 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
| *accessKey* (producer) | Amazon AWS Access Key |  | String
| *secretKey* (producer) | Amazon AWS Secret Key |  | String
| *region* (producer) | The region in which MQ client needs to work |  | String
| *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
|===


=== Query Parameters (10 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *accessKey* (producer) | Amazon AWS Access Key |  | String
| *amazonMqClient* (producer) | To use a existing configured AmazonMQClient as client |  | AmazonMQ
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *operation* (producer) | *Required* The operation to perform. It can be listBrokers,createBroker,deleteBroker |  | MQOperations
| *proxyHost* (producer) | To define a proxy host when instantiating the MQ client |  | String
| *proxyPort* (producer) | To define a proxy port when instantiating the MQ client |  | Integer
| *region* (producer) | The region in which MQ client needs to work. When using this parameter, the configuration will expect the capitalized name of the region (for example AP_EAST_1) You'll need to use the name Regions.EU_WEST_1.name() |  | String
| *secretKey* (producer) | Amazon AWS Secret Key |  | String
| *basicPropertyBinding* (advanced) | Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *synchronous* (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean
|===
// 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 12 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.configuration.access-key* | Amazon AWS Access Key |  | String
| *camel.component.aws-mq.configuration.amazon-mq-client* | To use a existing configured AmazonMQClient as client |  | AmazonMQ
| *camel.component.aws-mq.configuration.operation* | The operation to perform. It can be listBrokers,createBroker,deleteBroker |  | MQOperations
| *camel.component.aws-mq.configuration.proxy-host* | To define a proxy host when instantiating the MQ client |  | String
| *camel.component.aws-mq.configuration.proxy-port* | To define a proxy port when instantiating the MQ client |  | Integer
| *camel.component.aws-mq.configuration.region* | The region in which MQ client needs to work. When using this parameter, the configuration will expect the capitalized name of the region (for example AP_EAST_1) You'll need to use the name Regions.EU_WEST_1.name() |  | String
| *camel.component.aws-mq.configuration.secret-key* | Amazon AWS Secret Key |  | String
| *camel.component.aws-mq.enabled* | Whether to enable auto configuration of the aws-mq component. This is enabled by default. |  | Boolean
| *camel.component.aws-mq.region* | The region in which MQ client needs to work |  | String
| *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/amazon-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 MQ 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.
|=======================================================================

=== MQ Producer operations

Camel-AWS MQ component provides the following operation on the producer side:

- listBrokers
- createBroker
- deleteBroker
- rebootBroker
- updateBroker
- describeBroker

== Producer Examples

- listBrokers: this operation will list the available MQ Brokers in AWS

[source,java]
--------------------------------------------------------------------------------
from("direct:listBrokers")
    .to("aws-mq://test?amazonMqClient=#amazonMqClient&operation=listBrokers")
--------------------------------------------------------------------------------

== Automatic detection of AmazonMQ client in registry

The component is capable of detecting 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.
