Spring异步和可完成的未来无法获得结果

Spring 4.3和Java 8 配置了弹簧

@Repository
public class EmployeeRepostiry {

 @Async
 public CompleteableFuture<StatusVO> getEmployee(String id) {
  StatusVo status = new StatusVO();
   return CompletableFuture.completedFuture(status);
 }
}

CallingService cclass:

@Service
public class EmployeeService {

 @Autowired public EmployeeRepostiry employeeReporsitory;

 public List<StatusVO> getEmployee(List<String> ids) {
  List<StatusVo> returnStatus = new ArrayList<StatusVO>();
   List<CompleteableFuture<StatusVO>> statsuss = new ArrayList<CompleteableFuture<StatusVO>>();
   for(String id: ids) {
    statsuss.add(employeeReporsitory.getEmployee(id));
   }
   try {
       CompletableFuture.allOf(statsuss.toArray(new CompletableFuture[statsuss.size()])).join();
       } catch(Exception e){
          e.printstacktracce();
          }
   Logger.debug("not coming to this line");    //Not coming here

returnStatus = statsuss.stream().map(completableStatus -> {
        ServiceActionStatusVO statusVO = null;
        try {
            statusVO = completableStatus.get();
        } catch (InterruptedException | ExecutionException e) {
            statusVO = new StatusVO();
            statusVO.setStatus(Constants.ERROR);
            statusVO.setStatusText(e.getMessage());
            LOGGER.error("Failed on the state of execution ",e);
        }
        return statusVO;

    }).collect(Collectors.toList());
   return returnStatus ;
 }
}

async正在成功执行,并且还在异步线程中运行,并且所有ID都已完成。但声明不是在join();之后发表的 它在连接后挂起并且所有异步任务都被创建,我试图捕获一个通用异常并且没有返回
