AWS 2 Translate Component

Since Camel 3.1

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.

The AWS2 Translate component is not supported in OSGI

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 2 Translate component supports 6 options, which are listed below.

Name Description Default Type

configuration (advanced)

The AWS Translate default configuration

Translate2Configuration

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

The AWS 2 Translate endpoint is configured using URI syntax:

aws2-translate:label

with the following path and query parameters:

Path Parameters (1 parameters):

To define a proxy host when instantiating the Translate client

String

proxyPort (producer)

To define a proxy port when instantiating the Translate client

Integer

region (producer)

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

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

CamelAwsTranslateTerminologyNames

String

The terminologies to use

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 TranslateClient client in registry

The component is capable of detecting the presence of an TranslateClient 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("aws2-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-aws2-translate</artifactId>
    <version>${camel-version}</version>
</dependency>

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