Подключение к PostgreSQL из приложения OSGI развернуто в контейнере Karaf

StackOverflow https://stackoverflow.com//questions/23057562

Вопрос

Я использую Hibernate для подключения к PostgreSQL из контейнера KARAF 2.3.4, когда я развернул мой пакет, есть исключение, говоря Javax.Naming.nomenotfoundException OSGI: Service / javax.sql.dataSource / "(Osgi.jndi. .service.name= JDBC / postgresds).

Вот мой файл сохранения .xml

Я решил эту проблему, и я обновил список файлов, как сказал M. Cristian, но является другой странной проблемой: при перезапуске Karaf и попытка вставить данные через консоль Karaf Консоль Print: не активная транзакция, поэтому Я попробовал другой способ, используя EntityManager, и проблема больше не появляется.

Это было полезно?

Решение

Ваш код не может работать, так как DataSource опубликован в том же контексте чертежа, где используется блок постоянства.

Проблема в том, что план будет ждать инъекции службы EnitityManagerFactory.Таким образом, DataSource никогда не будет опубликован.Овен JPA обнаружит, что он должен создать EntityManagerFactory для вашего пакета, но время ожидания попытки найти источника данных.

Так что поставьте источник данных в пучок сковороды, и он должен работать.
