Html

            <form th:action="@{/deleteCartItem(id=${produkt.product.id})}" th:object="${produkty}" method="post">
                <div class="text-right">
                    <input type="submit" value="Delete" class="btn-sm btn-danger" />
                </div>
            </form>

Cart controller 

@GetMapping("/kosik")
public String kosik(Principal principal,Model model){
    User user = userServices.findByEmail(principal.getName());
    Cart cart = cartServices.findCartByUser(user);
    model.addAttribute("produkty",cartItemServices.findAllCartItems(cart));
    model.addAttribute("cart",cartServices.findCartByUser(user));
    model.addAttribute("user",user);
    return "cart";
}

Delete method

@PostMapping("/deleteCartItem")
public String deleteCartItem(@ModelAttribute CartItem cartItem){
    cartItemServices.deleteCartItem(cartItem.getCartItemId());
    return "redirect:/kosik";
}

Service

public void deleteCartItem(Integer id){
        cartItemRepository.deleteById(id);
    }

CartItem Entity

@Entity
public class CartItem {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer cartItemId;
    @NotNull
    @Max(11)
    private int quantity;
    private double price;

    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "product_id")
    private Product product;

    @ManyToOne
    @JoinColumn(name = "cart_id")
    private Cart cart;

Getting cartitem id works, but i cant delete cartItem.. I also tryied delete it not by id, but delete cartItem instantly..

Since your entity don't have id field as primary key. It's not working.

Define the below method in CartItemRepository and use it to delete the Object.

Long deleteByCartItemId(Long id);

Or rename the cartItemId field as id.
