私はSpring MVC RESTfulアプリで動作し、持続している間にConstraintViolationExceptionを取得します。以下に提供されたエラーメッセージ、ConstraintViolationException：永続中にクラス[.... entities.WalletInfo]の検証が失敗しました
Exception in thread " STARTING" javax.validation.ConstraintViolationException: Validation failed for classes [mobi.puut.entities.WalletInfo] during persist time for groups [javax.validation.groups.Default, ]

プロジェクトの構造を以下に提供され、
以下provicedエラーに向けサンプルコード、
@Transactional(rollbackFor = Exception.class)
public WalletInfo create(String name, String address) {
// create the WalletInfo entity with provided name and address
WalletInfo walletInfo = new WalletInfo();
walletInfo.setAddress(address);
walletInfo.setName(name);
// persist the created instance into the database
sessionFactory.getCurrentSession().persist(walletInfo);
return walletInfo;
}
protected WalletInfo createWalletInfo(final String walletName, final String address) {
return walletInfoDao.create(walletName, address);
}
public synchronized WalletInfo generateAddress(final String walletName, String currencyName) {
// get the WalletInfo entity from the database with the wallet and the currency name
WalletInfo walletInfo = walletInfoDao.getWalletInfoWithWalletNameAndCurrency(walletName, currencyName);
// generate wallet, if the wallet is not
// generated previously
if (walletInfo == null) {
if (genWalletMap.get(walletName) == null) {
logger.info("Wallet name that we are workign on {}", walletName);
final WalletManager walletManager = WalletManager.setupWallet(walletName);
walletManager.addWalletSetupCompletedListener((wallet) -> {
Address address = wallet.currentReceiveAddress();
/*at mobi.puut.services.WalletService.lambda$generateAddress$0(WalletService.java:97) */
WalletInfo newWallet = createWalletInfo(walletName, address.toString());
walletMangersMap.put(newWallet.getId(), walletManager);
genWalletMap.remove(walletName);
});
genWalletMap.put(walletName, walletManager);
}
return walletInfo;
}
return null;
}
private void setupWalletKit(final String walletId) {
File directory = getWalletDirectory(walletId);
// if the seed is not null, that means we are restoring from the backup
bitcoin = new WalletAppKit(networkParameters, directory, WALLET_FILE_NAME) {
@Override
protected void onSetupCompleted() {
// Don't make the user wait for confirmations
// they're sending their own money anyway!!
bitcoin.wallet().allowSpendingUnconfirmedTransactions();
Wallet wallet = bitcoin.wallet();
model.setWallet(wallet);
/* lambda$onSetupCompleted$0(WalletManager.java:109) */
setupCompletedListeners.forEach(listener -> listener.onSetupCompleted(wallet));
}
};
// some code
}
設けWalletInfoエンティティ、
@Entity
@Table(name = "wallet_info")
public class WalletInfo {
@Id
@Column(name = "id")
// @NotNull
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@NotNull
@Column(name = "name")
private String name;
@NotNull
@Column(name = "address")
private String address;
@NotNull
@Column(name = "currency")
private String currency;
public Long getId() {
return id;
}
public WalletInfo(@NotNull String name, @NotNull String address, @NotNull String currency) {
this.name = name;
this.address = address;
this.currency = currency;
}
public WalletInfo(@NotNull String name, @NotNull String address) {
this.name = name;
this.address = address;
}
public WalletInfo() {
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getCurrency() {
return currency;
}
public void setCurrency(String currency) {
this.currency = currency;
}
}
ここで問題と解決方法を教えてください。
誰かが質問を閉じる理由を提示している場合は、質問を更新できます。私にとっては、これは正当なプログラミング問題であり、解決する必要があります。 – Arefe
メッセージはクリアです。 'id'と' currency'はNULLであってはいけません。 – Zico
可能な解決策（あなたのデータベースは言及していませんでした）： 'Generation'.IDENTITYの' id'カラムがAUTO INCREMENTEDであることを確認し、 'currency'をNULLとして保存したい場合は、カラムにNULLデータを保存できます。 – Zico
