JPA实体与自身有关

Question

我有一个名为“帐户”的表。 在此表上，将有与父母有关的父母和子帐户。 我的想法是使用一个实体，一对多且一对​​一的关系。

实体看起来像这样：

@Entity
@Getter
@Setter
public class Accounts implements Serializable {

@Id
@Column(name = "ACCOUNT_ID", nullable = false)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "account_id_generator")
@SequenceGenerator(name="account_id_generator", sequenceName = "ACCOUNT_ID_seq", allocationSize = 1)
Long accountId;

@Column(name = "ACCOUNT")
String accountType;

@Column(name = "FK_SUB_ACCOUNT")
Long fkSubAccount;

@OneToMany(cascade = CascadeType.ALL, mappedBy = "subAccount")
List<Accounts> subAccounts = new ArrayList<>();

@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "fk_sub_account", updateable = false, insertable = true, referenceColumn = "account_id")
Account subAccount;

...
Some other attributes here, they are being populated by jpa

}

我的填充方式：

var account = new Account();
account.setAccountType("Parent");

var subAccount = new Account();
List<Account> subAccounts = new ArrayList<>();
subAccount.setAccountType("Sub");
subAccount.setSubAccount(account);
subAccount.getSubAccounts.addAll(List.of(account));
account.setSubAccount(subAccount);
subAccounts.add(subAccount);

account.getSubAccounts().addAll(subAccounts);

repository.save(account);

我能够看到除fksubaccount以外的所有属性 - null。 我做错了什么？

我有一些具有类似设置的桌子，除了它们在不同的实体上，而且它们工作正常。
