JpaTransactionManager аварийно завершает работу при весеннем запуске

1 голос
/ 14 июня 2019

Я использую Hibernate для подключения к кластеру AWS Aurora из моего весеннего веб-приложения.Когда я запускаю его локально и в TEST env, все работает, но в среде PROD веб-приложение вылетает без каких-либо ошибок.Поскольку обе среды используют одни и те же конфиги в отношении соединения hibernate / DB, я подозреваю, что проблема с зависимостью maven или какая-то странная неверная конфигурация в Spring.

Попытка также удалить кэш м2 с машин сборки, не помогло.

Журналы из приложения:

Приложение просто вылетает после, никакой дополнительной информации /исключения.

Использование: 

public class HibernateConnection {

    @PersistenceContext
    private final EntityManager entityManager;

    public HibernateConnection(EntityManager entityManager) {
        this.entityManager = entityManager;
    }
    ....
}

Редактировать: я включил отладку.В END PROD я получаю эти журналы непосредственно перед сбоем: 

DEBUG 2019-06-14 05:48:48.487 UTC message="Registering IdentifierGenerator strategy [sequence-identity] -> [org.hibernate.id.SequenceIdentityGenerator]"

В то время как в TEST env I запуск продолжается, и я получаю эти журналы:

Так что похоже на приложениеаварийно завершает работу после установления соединения с БД.

Так что, очевидно, URL указывал на кластер, который был настроен с группой безопасности, которая не включала мой сервер. Тихий сбой проблематичен, но ¯ \ _ (ツ) _ / ¯
