Class AsyncFeign<C>

java.lang.Object

feign.AsyncFeign<C>

@Experimental
public final class AsyncFeign<C>
extends Object

Enhances Feign to provide support for asynchronous clients. Context (for example for session cookies or tokens) is explicit, as calls for the same session may be done across several threads.

Retryer is not supported in this model, as that is a blocking API. ExceptionPropagationPolicy is made redundant as RetryableException is never thrown.
Alternative approaches to retrying can be handled through clients.

Target interface methods must return CompletableFuture with a non-wildcard type. As the completion is done by the AsyncClient, it is important that any subsequent processing on the thread be short - generally, this should involve notifying some other thread of the work to be done (for example, creating and submitting a task to an ExecutorService).
