通过注释使用Hibernate UUIDGenerator

hibernate

我使用我的uuid如下:

@Id
@GeneratedValue(generator = "uuid")
@GenericGenerator(name = "uuid", strategy = "uuid")
@Column(name = "uuid", unique = true)
private String uuid;

但是我收到了一个聪明的Hibernate警告:

使用org.hibernate.id.UUIDHexGenerator不会生成符合IETF RFC
4122的UUID值;考虑改用org.hibernate.id.UUIDGenerator

所以我想切换到org.hibernate.id.UUIDGenerator,现在我的问题是如何将其告知Hibernate的生成器。我看到有人用它作为“hibernateuuid”-这是我尝试过的方法,但结果是负面的:

@Id
@GeneratedValue(generator = "hibernate-uuid")
@GenericGenerator(name = "hibernate-uuid", strategy = "hibernate-uuid")
@Column(name = "uuid", unique = true)
private String uuid;
