Hibernate 5 Oracle OS Authentication

Hibernate ORM
2

The hibernate.connection.driver_class only supports user/password authentication modes.

As explained here, this is what you should use instead:

String url = "jdbc:oracle:thin:@oracleserver.mydomain.com:5521:dbja"
Driver driver = new oracle.jdbc.OracleDriver();
DriverManager.registerDriver(driver);
Properties props = new Properties();
Connection conn = DriverManager.getConnection( url, props );

You can use a custom Hibernate ConnectionProvider that does this or create a custom DataSource that you provide via the hibernate.connection.datasource property using programmatic boostrap or JNDI.
