JPA Composite Key: Avoid Unnecessary of Table Creation

Question

I am learning JPA.

I need to create 3 tables, product (pk => id), cart (pk => id), cart_details (pk also fk => product_id, cart_id).

The relation is : One cart can contain multiple cart_details, one cart_details can contain multiple product and one product can be put on multiple cart_details. I need only 3 tables, but JPA creates 4 tables for me: product, cart, cart_details, cart_details_product

@Entity
@Table(name = "product")
public class Product implements Serializable {

    private static final long serialVersionUID = 1L;
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;
    
    @NotBlank
    @Size(max = 50)
    private String name;
    
    @Size(max = 300)
    private String description;
    
    @NotNull
    private Double price;
    
    private int qty;
    
    @Column(name = "created_date")
    private Date createdDate;
    
    @Column(name = "updated_date")
    private Date updatedDate;
}

@Entity
@Table(name = "cart")
public class Cart implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(name = "total_price")
    private double totalPrice;
    
    @Column(name = "created_date")
    private Date createdDate;
    
    @Column(name = "updated_date")
    private Date updatedDate;

}

@Entity
@Table(name = "cart_details")
public class CartDetails implements Serializable {
    private static final long serialVersionUID = 1L;

    @EmbeddedId
    private CartDetailsId id;

    @MapsId("cartId")
    @ManyToOne
    @JoinColumn(name = "cart_id", referencedColumnName = "id", insertable = false, updatable = false)
    private Cart cart;

    @ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "product_id", referencedColumnName = "id")
    private Set<Product> product;

    private int quantity;

    private double price;

}

@Embeddable
public class CartDetailsId implements Serializable {
    private static final long serialVersionUID = 1L;
    
    @Column(name = "cart_id")
    private Long cartId;
    
    @Column(name = "product_id")
    private Long productId;

}

How to avoid creation of this table (cart_details_product)? I think i don't need this table.
