This is a wrapper around the Apache HTTP components async client to send Server-Sent Events.
implementation 'dev.manpreet:apache-sseclient:1.0'
Create an instance of the async client & start it
CloseableHttpAsyncClient asyncClient = HttpAsyncClients.createDefault();
asyncClient.start();
Create the request.
SseRequest request = new SseRequest(YOUR_REQUEST_URI);
Create the SSE client instance and provide ExecutorService instance to run the requests in a new thread.
ApacheHttpSseClient sseClient = new ApacheHttpSseClient(asyncClient, Executors.newFixedThreadPool(CONCURRENT_SSE_STREAMS));
Execute the request and get the Future response instance.
Future<SseResponse> sseResponse = sseClient.execute(request);
Created by @ytoh & @manpreet333 when in the middle of a project we realized Apache client doesn't have this functionality.
