Hibernate + Derby. База данных не найдена

Question

Я создал DBUSER база данных с USERS стол. Но когда я пытаюсь подключиться к базе данных, я принимаю SQLException. Также я могу подключиться к базе данных, используя ij.

Answer 1

Вы можете попробовать USI ng create = true с строкой url.

<property name=”hibernate.connection.url”>jdbc:derby:DBUSER;create=true</property> 

Это creates стандартной базы данных, указанные в соединении с базой данных системы URL Derby, а затем подключается к нему. Если база данных не может быть создана, в журнале ошибок появится ошибка, и попытка подключения завершится неудачей с помощью SQLException, указывающего, что база данных не может быть найдена.

Если база данных уже существует, создается соединение с существующей базой данных и выдается SQLWarning.
