Springboot GenerationType.UUID not working

@Table(name = "Product")
public class Product {

    @Id
    @GeneratedValue(strategy = GenerationType.UUID)
    private UUID id;
@Table(name = "Product")
public class Product {

    @Id
    @GeneratedValue(strategy = GenerationType.UUID)
    private UUID id;
On create drop the sql field becomes: 
id uuid not null primary key,
id uuid not null primary key,
upon inserting a row without specifying my Id field i get the error: 
[23502] ERROR: null value in column "id" of relation "product" violates not-null constraint
[23502] ERROR: null value in column "id" of relation "product" violates not-null constraint

Hey Edd, you need to call myProduct.setId(UUID.randomUUID()); before saving to the database.

That is bad advice. JPA or spring should do this for you Set strategy to Auto, that should work or, extend AbstractPersistable<UUID>, and remove all id related stuff from your own entity
