Dependency Module

The DI module uses Guice as a dependency injection container of the SDK. All service interfaces that are

Service Binding

All Services are bound to their implementations within the configure() method of the SdkModule. New Implementations or Providers can be added here can be registered here.

  @Override
    protected void configure() {

        bindConfigProperties();

        bind(CryptoService.class).to(JWECryptoService.class);
        bind(CertificateValidator.class).to(KeyValidator.class);
        bind(MetadataValidator.class).to(MetadataSubmissionValidator.class);
        bind(MetadataService.class).to(MetadataUploadService.class);

        bind(Sender.class).to(SubmissionSender.class);
        bind(Subscriber.class).to(SubmissionSubscriber.class);
    }

The actual injection can be done in three ways via @Inject:

• Parameter Injection
• Constructor Injection
• Getting the Service directly from the DI Container

Application Properties

The sdk can be externally configured via set property keys in sdk-config/sdk.properties. Those are keys are loaded on the guice initialization and can be accessed via the @Named Annotation. See Guice for further information on the usage.
