How put list object from JSON in MySQL

I need to put and get data from MySql with spring boot (Hibernate, Jackson)

Sample JSON:

[
    {
        "name": "Product1",
        "colors": [
            {
                "color": [
                    "#dddd33",
                    "#676767"
                ]
            },
            {
                "color": [
                    "#FFdDFF"
                ]
            }
        ]
    }
]

Same JSON I want to receive but added "id". What should I do to achieve this?

Object:

@Entity
public class Product {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @JsonProperty("name")
    private String name;

    @JsonProperty("colors")
    @OneToMany(mappedBy = "product_id")
    private Set<Color> colors;
}

@Entity
public class Color {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private Long product_id;

    @JsonProperty("color")
    @CollectionTable(name = "color", joinColumns = @JoinColumn(name = "color_id"))
    @Column(name = "color")
    @ElementCollection
    @OrderBy
    private List<String> color;
}

This not work I get error java.sql.SQLException: Field 'id' doesn't have a default value
