Class ExternalDatabase

java.lang.Object

org.wamblee.test.persistence.AbstractDatabase

org.wamblee.test.persistence.ExternalDatabase

All Implemented Interfaces:

Database

public class ExternalDatabase
extends AbstractDatabase

Database that encapsulates connection to an external database. Database connection details can be configured through system properties and environment variables, see DB_URL_PROP, DB_USER_PROP, and {@link #DB_PASSWORD_PROP|. This class assumes modern database drivers that work together with java.util.ServiceLoader so that explicitly doing a Class.forName() is not necessary to load the database driver.
