我有一个控制器方法，它更新订单实体的某些字段。我在调试模式下跟踪了控制器方法的执行流程。我发现事务提交过早。事务在调用存储库更新方法后立即提交。这是什么问题？
源代码在下面。
//控制器

@RestController
@RequestMapping(value = "/test", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
public class TxTestController extends BaseController {

    @Autowired
    private OrderRepository orderRepository;

    @Transactional
    @GetMapping(value = "/update")
    public void updateOrder() throws Exception {
        Order order = orderRepository.findAll().get(0);
        order.setFeeRemains(order.getFeeRemains().add(BigDecimal.valueOf(100000000)));

        orderRepository.updateOrder(order.getId(), order.getRemains(), order.getFeeRemains(), order.getStatus());
        // The transaction is commited after execution of the above line.
        // and the external database tools can see the changed data from here.
        // So no way to rollback transaction after this line.

        System.out.println(order);
        // do another persistence jobs
    }
}

字符串
// Repository

public interface OrderRepository extends JpaRepository<Order, String>, QueryDslPredicateExecutor<Order> {
@Modifying
@Query("update Order o set o.remains = :remains, o.feeRemains = :feeRemains, o.status = :status where o.id = :orderId")
void updateOrder(@Param("orderId") String orderId,
                 @Param("remains") BigDecimal remains,
                 @Param("feeRemains") BigDecimal feeRemains,
                 @Param("status") Order.Status status);
}

如果我从控制器方法中删除@Transactional注解，则会发生javax.persistence. TransactionAddressedException。
