In this mode, a method will be configured with a return type by wrapping the result with the Future type:

@Service
public class BankAsyncService {
  
  private static final Logger LOGGER = 
  Logger.getLogger(BankAsyncService.class);
  
  @Async
    public Future<String> syncCustomerAccount() throws 
    InterruptedException {
    LOGGER.info("Sync Account Processing Started - Thread id: " + 
    Thread.currentThread().getId());
    
    Thread.sleep(2000);
    
    String processInfo = String.format("Sync Account Processing 
    Completed - Thread Name= %d, Thread Name= %s", 
    Thread.currentThread().getId(), 
    Thread.currentThread().getName());
    
    LOGGER.info(processInfo);
    
    return new AsyncResult<String>(processInfo);
    }
}

Spring also provides support for the AsyncResult class, which implements the Future interface. It can be used to track the result of asynchronous method invocation.
