Java可调用和未来

Question

我正在使用Java Callable，所以我正在编写一个运行并行任务的函数，它在第一次调用时运行完美，但对于另一个调用，我的函数重复迭代次数 请有人能告诉我哪里弄错了 这是我的代码：

@Autowired
RechercheTabouService rechercheTabouService;
@Autowired
PlannedTripService plannedTripService;

public void test() {
    System.out.println("start test");
    DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
    Date date;
    try {
        date = dateFormat.parse("12/11/2017");
        rechercheTabouService.setPlannedTrips(plannedTripService.findPlannedTripByDate(date, 1512127292, 200));
    } catch (Exception e) {
        e.printStackTrace();
    }

    rechercheTabouService.setInitialSolution();
    List<Trajet> initial = rechercheTabouService.getInitialSolution();
    rechercheTabouService.setInitialCost(initial);

    System.out.println("initial :" + rechercheTabouService.calculCostSolution(initial));

    @RequestMapping("/tabou")
    public Integer runtest () {
        test();
        return 1;
    }
}

这是2次successif调用的结果：    

我从这个控制器调用我的函数：

SELECT MainRequest.RequestID, UKINT, ReasonForTrip
       ,TripNumber, Itinerary.[Start Date], Itinerary.[End Date]
FROM MainRequest
LEFT JOIN
(
    SELECT RequestID, Min(StartDate) As [Start Date]
           ,MAX(EndDate) As [End Date]
    FROM Itinerary
    GROUP by RequestID
) Itinerary
    ON (MainRequest.RequestID = Itinerary.RequestID)
