Hibernate is getting wrong ID values when using UUID as primary key

Question

My entity:

@Entity
@Table(name = "eh_portal")
public class PortalEntity {

    @Id
    @Column(name = "id", columnDefinition = "CHAR(36)")
    private UUID id; //java.util.UUID;

    @Column(name = "name")
    private String name;

    @Column(name = "url")
    private String url;

    // -- Constructor for Hibernate --
    protected PortalEntity() {
    }

    // -- Constructor for new entity in service code --
    public PortalEntity(final UUID id) {
        this.id = id;
    }
    .... getters and setters ommited
}

Respository is Spring DATA JPA:

public interface PortalRepository extends CrudRepository<PortalEntity, UUID> {

}

MYSQL 5 Database table definition:

CREATE TABLE `eh_portal` (
  `id` char(36) NOT NULL COMMENT 'UUID',
  `name` varchar(255) NOT NULL,
  `url` varchar(255) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `url_UNIQUE` (`url`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

The problem is, Hibernate is returning obviously wrong data - see screenshots below Mysql workbench:

Actual web page where I get entities thru Spring Data JPA:

You can see that UUIDs are obviously differrent, while other columns are correct. What is wrong here? (Spring 4, Hibernate 4, Spring DATA JPA, Mysql 5)

Answer 1

Try using @Type(type="uuid-char").
