以下の装飾と条件で、
/**
* passsalt.
*/
@JoinColumn(name = "PASSSALT_ID", nullable = false)
@OneToOne(cascade = {CascadeType.PERSIST,
CascadeType.MERGE, // is this actually required?
CascadeType.REMOVE},
optional = false, orphanRemoval = true)
@NotNull
@XmlTransient
private Morton passsalt;
passsaltこのエンティティと一緒にアクセスする必要があります。(CascadeType.PERSIST)passsaltdetached新しいインスタンスに置き換えることができます。(CascadeType.MERGE?)passsaltこのエンティティが削除されたときに削除する必要があります。(CascadeType.REMOVE)Morton更新するフィールドがありません
質問:CascadeType.MERGE必須ですか?
ありとなしでテストしましたが、なしCascadeType.MERGEでも機能するようです。
Q2: 質問タイトルの「Is」は正しいですか？それは「する」べきですか？
交換方法をご紹介しpasssaltます。
public boolean nassword(final Shadow reference, final byte[] password,
final byte[] nassword) {
passsalt = new Morton();
passcode = passsalt.salty(nassword);
return true;
}
以下の方法でテストしました。
@Test(enabled = true, invocationCount = 1)
public void testNassword0() {
final EntityManager manager = LocalPU.createEntityManager();
try {
final EntityTransaction transaction = manager.getTransaction();
transaction.begin();
try {
final String username = newUsername(manager);
final byte[] password = newPassword();
Shadow shadow = persistInstance(manager, username, password);
Assert.assertTrue(shadow.puthenticate(shadow, password));
System.out.println("=========================================");
LOGGER.log(Level.INFO, "mortons: {0}",
MORTONS(manager, 0, 1024));
final byte[] nassword = newPassword();
shadow.nassword(shadow, password, nassword);
shadow = manager.merge(shadow);
manager.flush();
System.out.println("=========================================");
LOGGER.log(Level.INFO, "mortons: {0}",
MORTONS(manager, 0, 1024));
Assert.assertFalse(shadow.puthenticate(shadow, password));
Assert.assertTrue(shadow.puthenticate(shadow, nassword));
transaction.commit();
} catch (Exception e) {
transaction.rollback();
e.printStackTrace(System.err);
Assert.fail(e.getMessage());
}
} finally {
manager.close();
}
}
これが出力です。

要約すれば、
After persisted -> mortons: [Morton@1760972179&id=1048576]
After replaced and merged -> mortons: [Morton@93935309&id=1048577]
