Hands-On High Performance with Spring 5

Result retrieval mode

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

@Servicepublic 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 ...
