onComplete

Description

Evaluates its parameter of type CompletionStage<T>, and once it has been completed, extracts its result as a value of type Try<T> and passes it to the inner route. A Try<T> can either be a Success containing the T value or a Failure containing the Throwable.

To handle the Failure case automatically and only work with the result value, use onSuccess.

To complete with a successful result automatically and just handle the failure result, use completeOrRecoverWith, instead.
