春の休止状態を使用して、安らかなサービスアプリを作成しています。操作が失敗したときにエラー メッセージを返したい。たとえば、重複した主キーが検出された場合にアカウントを作成しているときに、ユーザー名が利用できないというメッセージを設定したいと考えています。

try
{
    Account account = accountDao.createAccount(accName, emailAdd);
    result.accountId = account.getIdAccount();
}
catch (DataAccessException e)
{
    result.errorMessage = "something like this account name is already taken"; <*****
    Throwable th = e.getCause();
    if(th!=null && th instanceof ConstraintViolationException)
    {
        ConstraintViolationException cve = (ConstraintViolationException) th;
        log.debug("Error code = " + cve.getErrorCode() + " ConstraintName = " + cve.getConstraintName());
    }
}
catch (Exception e)
{
    result.errorMessage = "failed to create account";
}

したがって、stacktace を使用すると、内部例外が

Caused by: org.hibernate.exception.ConstraintViolationException: Duplicate entry 'my account name' for key 'name_account'

しかし、取得しようとするとcve.getConstraintName()、null が返されます。(cve.getConstraintName()は 1062)

私が探しているものを手に入れる方法はありますか？

参考までに、これは完全なスタック トレースです。

をチェックして、違反した DB 制約を確認しますConstraintViolationException。getConstraintName()そこで、どのエンティティが問題を引き起こしているかを確認できます。以下は、私が使用したサンプルコードです。

} catch (ConstraintViolationException conEx) {
            if (conEx.getConstraintName().contains("PROJECT_UK")) {
                //TODO Project Entity is violating it's constrain
            } else if (conEx.getConstraintName().contains(
                    "PROJECT_BATCH_CLASS_FK")) {
                //TODO BatchClass entity within Project is giving issue
            } else if (conEx.getConstraintName().contains("OPPRTNTY__UN")) {
                //TODO Project Entitiy is giving the issue
            } else {
                //TODO Unknown entity/constrain is causing the issue
            }
            LOGGER.ERROR( "My log message", conEx);

containsこのアプリを複数の DB スキーマで実行したいので、使用しました。デフォルトでgetConstraintNameは、次のようなDB名が付いてい ます

MyDBName.ConstrainName

org.springframework.dao をキャッチしてみてください。DataAccessExceptionの代わりにDataIntegrityViolationException

データを挿入または更新しようとした結果、整合性制約に違反した場合にスローされる例外。これは純粋にリレーショナルな概念ではないことに注意してください。ほとんどのデータベース タイプでは一意の主キーが必要です。
