Given
{noformat}@Entity(name = "Client")
public static class Client {
@Id
@GeneratedValue
private Long id;
private String name;
@Embedded
private Log log = new Log();
....
}
@Entity(name = "User")
@Table(name = "`User`")
public static class User {
@Id
@GeneratedValue
private Long id;
@Column(length = 120, nullable = false)
private String name;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "`idClient`")
private Client client;
.....
}
@Embeddable
public static class Log {
@Column(name = "`creationDate`", nullable = false)
private OffsetDateTime creationDate;
...
}{noformat}
the following code
{noformat}@Test
public void load() {
inTransaction(
session -> {
User user = session.find( User.class, userId );
}
);
}{noformat}
causes
{noformat}javax.persistence.PersistenceException: org.hibernate.PropertyValueException: not-null property references a null or transient value : Client.log.creationDate{noformat}
