org.hibernate.cfg
Class Configuration

java.lang.Object
  extended byorg.hibernate.cfg.Configuration
All Implemented Interfaces:
Serializable

public class Configuration
extends Object
implements Serializable

An instance of Configuration allows the application to specify properties and mapping documents to be used when creating a SessionFactory. Usually an application will create a single Configuration, build a single instance of SessionFactory and then instantiate Sessions in threads servicing client requests. The Configuration is meant only as an initialization-time object. SessionFactorys are immutable and do not retain any association back to the Configuration.

A new Configuration will use the properties specified in hibernate.properties by default.
