InvalidDataAccessResourceUsageException和SQLGrammarException

Question

当我尝试更新hibernate实体时，我得到了这个例外。可能是什么问题呢？

@Service
@Transactional
public class ProductServiceImpl implements ProductService {
...
@Override
public void updateAllStock() {
    products.getAllProducts().stream()
            .filter(e -> e.getUnitsInStock() < 500)
            .forEach(e -> products.updateStock(e.getProductId(), 
                       1000));
}

DAO

@Repository
public class ProductDaoImpl implements ProductDao {
...
@Override
public void updateStock(int productId, int numOfUnits) {
    Session currentSession = factory.getCurrentSession();
    Product product = currentSession.load(Product.class, productId);
    product.setUnitsInStock(product.getUnitsInStock() + numOfUnits);
}

编辑：添加堆栈跟踪：

我认为hibernate配置有问题吗？
