It may be easier to use the ThreadPoolTaskExecutor which is provided by Spring Boot with @EnableAsync and has the a similar signature to ExecutorService namely the submit method.

Example of use of it is

@Component
@lombok.RequiredArgsConstructor
public class MyComponent {
  private final ThreadPoolTaskExecutor taskExecutor;
  public void myMethod() throws Throwable {
    final Future<Void> future = taskExecutor.submit(
        () -> {
          ...
          return null;
        });
    
    try {
      ...
      future.get();
      ...
    } catch (ExecutionException e) {
      throw e.getCause();
    } catch (InterruptedException e) {
      Thread.currentThread().interrupt();
    }
  }
}

Here is an example:

  @Async
  public CompletableFuture<Void> foo()  {
       // Do some work
       return CompletableFuture.completedFuture(null);
  }
