Because strategy and UUIDGenerator is deprecated, this is the new UUID Generator:
@GenericGenerator(
name = "UUID",
type = org.hibernate.id.uuid.UuidGenerator.class
)
When using this, I get the following error:
Parameter 0 of constructor in org.hibernate.id.uuid.UuidGenerator required a bean of type 'org.hibernate.annotations.UuidGenerator' that could not be found
I wasn't able to find anything corresponding to this in the documentation.
For full disclosure, this is the whole annotation block used:
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "UUID")
@GenericGenerator(name = "UUID", type = org.hibernate.id.uuid.UuidGenerator.class)
@Column(...)
I really suggest you to use @UuidGenerator instead of
@GeneratedValue(strategy = GenerationType.AUTO, generator = "UUID")
@GenericGenerator(name = "UUID", type = org.hibernate.id.uuid.UuidGenerator.class)
Something like this:
@Id
@UuidGenerator
private UUID id; // or String
Because if you are going to check java docs of the annotation you will see that @UuidGenerator use
@IdGeneratorType( org.hibernate.id.uuid.UuidGenerator.class ) that you need.
About the problem i really dont know where can be the problem but the solution that i suggest will help you to do this replacement also when specifying @UuidGenerator, we can choose the concrete version of UUID to generate.
And also some motivation to use it is described into 8.5. User-defined generators
These APIs are new in Hibernate 6, and supersede the classic IdentifierGenerator interface and @GenericGenerator annotation from older versions of Hibernate.
