Environment (Hibernate Core Aggregator 3.6.10.Final API)

java.lang.Object
- org.hibernate.cfg.Environment

public final class Environment
extends Object

Provides access to configuration info passed in Properties objects.

Hibernate has two property scopes:

Factory-level properties may be passed to the SessionFactory when it instantiated. Each instance might have different property values. If no properties are specified, the factory calls Environment.getProperties().
System-level properties are shared by all factory instances and are always determined by the Environment properties.

The only system-level properties are

hibernate.jdbc.use_streams_for_binary
hibernate.cglib.use_reflection_optimizer

Environment properties are populated by calling System.getProperties() and then from a resource named /hibernate.properties if it exists. System properties override properties specified in hibernate.properties.

The SessionFactory is controlled by the following properties. Properties may be either be System properties, properties defined in a resource named /hibernate.properties or an instance of java.util.Properties passed to Configuration.buildSessionFactory()
