如何每5分钟运行一次调度程序任务

Question

我正在尝试使用ScheduledThreadPoolExecutor's scheduleAtFixedRate每5分钟运行一次任务，但它只是第一次运行，请让我知道我在这里做错了什么。感谢。

@RestController
@RequestMapping("/app")
public class MyRestController {
    private RequestValidator validator;
    final ScheduledThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(5);
    private MyOtherServiceResponse myOtherServiceResponse;

    @Autowired
    public MyRestController(RequestValidator validator, MyOtherServiceResponse myOtherServiceResponse){
        this.validator = validator;
        this.myOtherServiceResponse = myOtherServiceResponse;
        startScheduler();// calling scheduler for the first time to start 
    }

    @RequestMapping( value = "/getDetails/{prdId}", method= RequestMethod.GET, produces={"application/json"})
    public ResponseEntity<> getProductInfo(@PathVariable(value="prdId") String prdId) {
        long endTime = 0;
        long startTime = 0;
        startTime = System.currentTimeMillis();
        if((validator.validateRequest(prdId))== null) {
            ServiceRequest serviceRequest = validator.getServiceRequest();
            endTime = System.currentTimeMillis() - startTime;
            //getThisServiceResponse(serviceRequest, prdId); 
            System.out.println("Service final Time --------------    " + endTime + "  prdId : " + prdId);
            return new ResponseEntity<>(HttpStatus.OK);
        }
        else {
            errorResponse = validator.validateRequest(prdId);
            return new ResponseEntity<>(errorResponse, HttpStatus.OK);
        }

    }

    public void startScheduler(){
        executor.scheduleAtFixedRate(() -> myOtherServiceResponse.getOtherResponse(validator.getServiceRequest(), validator.PRDID), 0, 5, TimeUnit.MINUTES);
    }
}

MyController构造函数调用startScheduler()，但根据调度程序，它应该每5分钟运行一次getOtherResponse
