AWS Translate Component

Since Camel 3.0

Only producer is supported

The Translate component supports translate a text in multiple languages. AWS Translate clusters instances.

Prerequisites

You must have a valid Amazon Web Services developer account, and be signed up to use Amazon Translate. More information is available at Amazon Translate.

URI Format

aws-translate://label[?options]

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

URI Options

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

Name Description Default Type

configuration (advanced)

The AWS Translate default configuration

TranslateConfiguration

accessKey (producer)

Amazon AWS Access Key

String

secretKey (producer)

Amazon AWS Secret Key

String

region (producer)

The region in which Translate 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 Translate endpoint is configured using URI syntax:

aws-translate:label

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

label

Required Logical name

String

Query Parameters (12 parameters):

Name Description Default Type

accessKey (producer)

Amazon AWS Access Key

String

autodetectSourceLanguage (producer)

Being able to autodetect the source language

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

operation (producer)

Required The operation to perform

TranslateOperations

proxyHost (producer)

To define a proxy host when instantiating the Translate client

String

proxyPort (producer)

To define a proxy port when instantiating the Translate client

Integer

proxyProtocol (producer)

HTTPS

Protocol

region (producer)

The region in which Translate 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

translateClient (producer)

To use a existing configured AWS Translate as client

AmazonTranslate

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-translate-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

Boolean

camel.component.aws-translate.bridge-error-handler

camel.component.aws-translate.configuration.region

String

camel.component.aws-translate.configuration.secret-key

Amazon AWS Secret Key

String

To use a existing configured AWS Translate as client

AmazonTranslate

camel.component.aws-translate.enabled

Whether to enable auto configuration of the aws-translate component. This is enabled by default.

Boolean

camel.component.aws-translate.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.

false

Boolean

camel.component.aws-translate.region

String

camel.component.aws-translate.secret-key

Amazon AWS Secret Key

String

Required Translate component options

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

Usage

Message headers evaluated by the Translate producer

Header Type Description

CamelAwsTranslateSourceLanguage

String

The text source language

CamelAwsTranslateTargetLanguage

String

The text target language

CamelAwsTranslateOperation

String

The operation to perform

Translate Producer operations

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

  • translateText

Automatic detection of AmazonTranslate client in registry

The component is capable of detecting the presence of an AmazonTranslate 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.

Translate Text example

from("direct:start")
  .setHeader(TranslateConstants.SOURCE_LANGUAGE, TranslateLanguageEnum.ITALIAN)
  .setHeader(TranslateConstants.TARGET_LANGUAGE, TranslateLanguageEnum.GERMAN)
  .setBody("Ciao")
  .to("aws-translate://test?translateClient=#amazonTranslateClient&operation=translateText");

As result you’ll get an exchange containing the translated text.

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-translate</artifactId>
    <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel.
