Invalid property 'id' of bean class Could not find field for property during fallback access - spring

Question

Below is my Controller
#PostMapping(value="/shoppingcart")
ResponseEntity<ResponseDTO<ShoppingCartItem>>
insertItems(#RequestParam("cartId")Long cartId, #RequestParam ("itemsKey")
Long itemkey) {
ResponseDTO<ShoppingCartItem> responseDTO = new ResponseDTO<>();
Meta meta = new Meta();
ShoppingCartItem cartItem = null;
ShoppingCartItem saveItem = new ShoppingCartItem();
ShoppingCart cart = new ShoppingCart();
cart.setId(cartId);
Items item = new Items();
item.setId(itemkey);
saveItem.setCart(cart);
saveItem.setItem(item);
cartItem = shoppingCartItemService.save(saveItem);
return new ResponseEntity<ResponseDTO<ShoppingCartItem>>(responseDTO, HttpStatus.OK);
}
This is my Entity Class:
#Entity
#Table(name = "tb_shoppingcart_items")
public class ShoppingCartItem implements Serializable {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long cartItemId;
#ManyToOne
#MapsId("shoppingcartId")
private ShoppingCart cart;
#ManyToOne
#MapsId("itemsId")
private Items item;
#Column(name = "quantity")
private boolean quantity;
public Long getCartItemId() {
return cartItemId;
}
public void setCartItemId(Long cartItemId) {
this.cartItemId = cartItemId;
}
public ShoppingCart getCart() {
return cart;
}
public void setCart(ShoppingCart cart) {
this.cart = cart;
}
public Items getItem() {
return item;
}
public void setItem(Items item) {
this.item = item;
}
public boolean isQuantity() {
return quantity;
}
public void setQuantity(boolean quantity) {
this.quantity = quantity;
}
}
#Entity
#Table(name = "tb_shoppingcart")
public class ShoppingCart implements Serializable {
/**
*
*/
private static final long serialVersionUID = -2114870327410506836L;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
#Column(name = "dateCreated")
private Date datecreated;
/*
* #JsonIgnore
*
* #OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) List<Items> items
* = new ArrayList<>();
*/
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Date getDatecreated() {
return datecreated;
}
public void setDatecreated(Date datecreated) {
this.datecreated = datecreated;
}
/*
* public List<Items> getItems() { return items; }
*
* public void setItems(List<Items> items) { this.items = items; }
*/
}
I am getting the below exception while saving my shoppingcartItem in the databse:
