Как сохранить данные с помощью метода сохранения репозитория jpa ⇐ JAVA

[Anonymous]

При добавлении объекта из класса, реализованного службой, в интерфейс репозитория отображается успешное сообщение, но данные не вставляются в базу данных. Я вызываю метод save(entity) из интерфейса JpaRepository. вместо этого он показывает сообщение об успешном вставке записи.

Контроллер --- >>.

@Controller
@RequestMapping("/cart")
public class CartController {

@Autowired
CartService cartServices;

/**
* Get All records in Cart
*
* @return All Cart List
*/
@RequestMapping(value = "/list", method = RequestMethod.GET)
public @ResponseBody List getCart() {

List cartList = null;
try {
cartList = cartServices.getCartList();
if(cartList.isEmpty())
{
System.out.println("List is empty ");
}
} catch (Exception e) {
e.printStackTrace();
}

return cartList;
}
/**
* Add Cart
*
* @param representative
* @return Status
*/
@RequestMapping(value = "/create", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody Status addCart(@RequestBody Cart cart) {
System.out.println("i m from jpa controller");
try {
cartServices.save(cart);
return new Status(1, "Cart added Successfully !");
} catch (Exception e) {
// e.printStackTrace();
return new Status(0, e.toString());
}

}


Класс «Реализованный сервис» ------>>>>

@Service
public class CartServiceImpl implements CartService {

@Inject
CartRepository cartRepository;

/**
* Get All Cart
*
* @throws Exception
* @return All Cart List
*/

@Override
@Transactional
public List getCartList() throws Exception {
// TODO Auto-generated method stub
return cartRepository.findAll();
}

/**
* Add Cart
*
* @param cart
* @throws Exception
* @return Boolean
*/
@Override
@Transactional
public Cart save(Cart cart) throws Exception {
System.out.println("i m from jpa Service");

Cart cart1 = cartRepository.save(cart);
return cart1;
}
