AWS 2 Translate

Since Camel 3.1

Only producer is supported

The AWS2 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

aws2-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 17 options, which are listed below.

Name Description Default Type

autodetectSourceLanguage (producer)

Being able to autodetect the source language

false

boolean

autoDiscoverClient (common)

Setting the autoDiscoverClient mechanism, if true, the component will look for a client instance in the registry automatically otherwise it will skip that checking.

true

boolean

configuration (producer)

Component configuration

Translate2Configuration

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. The value can be one of: translateText

translateText

pojoRequest (producer)

If we want to use a POJO request as body or not

false

boolean

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)

To define a proxy protocol when instantiating the Translate client. The value can be one of: HTTP, HTTPS

HTTPS

Protocol

region (producer)

The region in which Translate client needs to work. When using this parameter, the configuration will expect the lowercase name of the region (for example ap-east-1) You’ll need to use the name Region.EU_WEST_1.id()

String

sourceLanguage (producer)

Source language to use

String

targetLanguage (producer)

Target language to use

String

translateClient (producer)

To use a existing configured AWS Translate as client

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

accessKey (security)

Amazon AWS Access Key

String

secretKey (security)

Amazon AWS Secret Key

String

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.

Using a POJO as body

Sometimes build an AWS Request can be complex, because of multiple options. We introduce the possibility to use a POJO as body. In AWS Translate the only operation available is TranslateText so you can do something like:

from("direct:start")
  .setBody(TranslateTextRequest.builder().sourceLanguageCode(Translate2LanguageEnum.ITALIAN.toString())
                    .targetLanguageCode(Translate2LanguageEnum.GERMAN.toString()).text("Ciao").build())
  .to("aws2-translate://test?translateClient=#amazonTranslateClient&operation=translateText&pojoRequest=true");

In this way you’ll pass the request directly without the need of passing headers and options specifically related to this operation.

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.

Spring Boot Auto-Configuration

When using aws2-translate with 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-aws2-translate-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
