Class DatabaseFactory

java.lang.Object
io.ebean.DatabaseFactory
public final class DatabaseFactory extends Object
Creates Database instances.

This uses either DatabaseConfig or properties in the application.properties file to configure and create a Database instance.

The Database instance can either be registered with the DB singleton or not. The DB singleton effectively holds a map of Database by a name. If the Database is registered with the DB singleton you can retrieve it later via DB.byName(String).

One Database can be nominated as the 'default/primary' Database. Many methods on the DB singleton such as DB.find(Class) are just a convenient way of using the 'default/primary' Database.

   config.setName("db");
   config.loadProperties();

      public static Database createWithContextClassLoader(DatabaseBuilder config, ClassLoader classLoader)
      Create using the DatabaseConfig additionally specifying a classLoader to use as the context class loader.
