How to create a completed instance of org.springframework.util.concurrent.ListenableFuture

Question

How to create a dummy instance of org.springframework.util.concurrent.ListenableFuture?

It should represents a completed task with a given result.

Answer 1

Assuming String result, you can use following:

    String result = "result";
    ListenableFuture<String> future = new AsyncResult<>(result);
    String dummy = future.get();

However, if you need, any object can be wrapped in AsyncResult.
