**Account.class** Client.class I manually initialize the Client and the Account, then set the account to the Client and try to save it. Here's what I get As you can see from here, the database is being saved to client_id = 0; How can this problem be solved? Thank you!

@Column(name = "client_id")
@GeneratedValue(generator = "gen")
@GenericGenerator(name = "gen", strategy = "foreign", parameters = { @Parameter(name = "property", value = "clientDTO") })
private int client_id;



@OneToOne(cascade = CascadeType.ALL)
private AccountDTO accountDTO;
