Save Object by uuid

[mai1015]

When save an object with UUID will trigger an error that try to convert long to uuid.
I assume that it is trying to read the id from database response and causing this error since the database is using UUID.

public class User implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
//    @Type(type = "uuid-char")
//    @GeneratedValue(generator = "UUID")
//    @GenericGenerator(name = "UUID", strategy = "org.hibernate.id.UUIDGenerator")
    private UUID id;

    @NotNull
    @Pattern(regexp = Constants.LOGIN_REGEX)
    @Size(min = 1, max = 50)
    private String login;

    @JsonIgnore
    @NotNull
    @Size(min = 60, max = 60)
    @Column("password_hash")
    private String password;
// other implmenetation
}
