AWS MQ Component

Since Camel 2.21

Only producer is supported

The MQ component supports create, run, start, stop and terminate 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 Amazon MQ.

URI Format

aws-mq://label[?options]

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

URI Options

The AWS MQ component supports 7 options, which are listed below.

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

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

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

The AWS MQ endpoint is configured using URI syntax:

aws-mq:label

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

Query Parameters (11 parameters):

Name Description Default Type

accessKey (producer)

String

amazonMqClient (producer)

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

Integer

proxyProtocol (producer)

HTTPS

Protocol

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

Spring Boot Auto-Configuration

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

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

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.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

Protocol

camel.component.aws-mq.configuration.region

String

camel.component.aws-mq.configuration.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.lazy-start-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.

String

camel.component.aws-mq.secret-key

String

Required MQ component options

You have to provide the amazonMqClient in the Registry or your accessKey and secretKey to access the Amazon MQ service.

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

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

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

<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.
