About the FIT-Connect Java SDK

The Java SDK for FIT-Connect enables to build clients for senders and subscribers without directly interacting with any REST-Endpoints. It provides a simple fluent API that guides through the creation and sending of a submission, as well as receiving submissions as a subscriber.

For further information, check out the official docs: FIT-Connect Documentation as well as the:

• Self-Service-Portal (Testing Environment)
• FITKO project website

Build Dependencies

This section lists major frameworks/libraries used in the SDK.

• Java 11 (LTS)

Modules

See the projects' module documentation for more specific information:

• API Module
• Core Module
• Client Module
• Open-API Module

Setup

The following steps show how to get the SDK running

1. Create and account on the self service portal
2. Get your sender/subscriber API-key credentials
3. Clone the sdk repo

External Configuration

Configuration properties e.g. for REST-API urls and proxy settings can be found in the HOCON config sdk.conf within the root folder of the project.

In order to run the SDK client a configuration needs to be provided as file in the same path as the jar (e.g. when the commandline client is used) or via reference using the environment variable CONFIG_LOCATION (e.g. when the SDK i used programmatically).

Usage

Sending

List<File> attachments = ... // Load e.g from local file system
        
        ClientFactory.senderClient()
        .withDestination(UUID.randomUUID())
        .withServiceType("ServiceName", "leika:key:service")
        .withAttachments(attachments)
        .withJsonData("{ caseSpecific: 'Data' }")
        .submit();

Subscribing

    var client = ClientFactory.subscriberClient();

    var submissions = client.getAvailableSubmissions(destinationId);
    
    var submissionId = ... // filter submission list for requested one ...      
            
    var submission = client.requestSubmission(submissionId)
    submission.getAttachments();
    submission.getMetadata();
    submission.getData();
