问题描述
我有一个Web应用程序,它使用spring boot作为后端,而vue.js作为前端,并且我有一个脚本python捕获,最后一个可以向数据库添加行,所以我需要将通知推送给用户,如何我可以吗?
@PostMapping("/plate")
public ResponseEntity<Void> createPositionOc(@RequestParam String plate) {
LocalDateTime myDateObj = LocalDateTime.Now();
DateTimeFormatter myFormatObj = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
List<Car> cars = carController.getAllCars();
boolean exist = cars.stream().anyMatch(o -> o.getPlate().equals(plate));
List<Car> carsIn = carController.getAllCarsIn();
boolean existIn = carsIn.stream().anyMatch(o -> o.getPlate().equals(plate));
List<Position> free = getAllPositiosFree();
PositionOcp position = new PositionOcp(free.get(0).getId_pos(),plate,myDateObj.format(myFormatObj));
if (exist && free.size() > 0 && !existIn) {
PositionOcp createdPositionOc = positionOcpRepository.save(position);
//send notification
}
return null;
}
