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.build()
property meaning
hibernate.dialect
classname of org.hibernate.dialect.Dialect subclass
hibernate.connection.provider_class
classname of ConnectionProvider
subclass (if not specified hueristics are used)
hibernate.connection.username database username
hibernate.connection.password database password
hibernate.connection.url
JDBC URL (when using java.sql.DriverManager)
hibernate.connection.driver_class
classname of JDBC driver
hibernate.connection.isolation
JDBC transaction isolation level (only when using
java.sql.DriverManager)
hibernate.connection.pool_size
the maximum size of the connection pool (only when using
java.sql.DriverManager)
hibernate.connection.datasource
databasource JNDI name (when using javax.sql.Datasource)
hibernate.jndi.url JNDI InitialContext URL
hibernate.jndi.class JNDI InitialContext classname
hibernate.max_fetch_depth
maximum depth of outer join fetching
hibernate.jdbc.batch_size
enable use of JDBC2 batch API for drivers which support it
hibernate.jdbc.fetch_size
set the JDBC fetch size
hibernate.jdbc.use_scrollable_resultset
enable use of JDBC2 scrollable resultsets (you only need this specify
this property when using user supplied connections)
hibernate.jdbc.use_getGeneratedKeys
enable use of JDBC3 PreparedStatement.getGeneratedKeys() to retrieve
natively generated keys after insert. Requires JDBC3+ driver and JRE1.4+
hibernate.hbm2ddl.auto
enable auto DDL export
hibernate.default_schema
use given schema name for unqualified tables (always optional)
hibernate.default_catalog
use given catalog name for unqualified tables (always optional)
hibernate.session_factory_name
If set, the factory attempts to bind this name to itself in the
JNDI context. This name is also used to support cross JVM
Session (de)serialization.
hibernate.transaction.jta.platform
classname of org.hibernate.engine.transaction.jta.platform.spi.JtaPlatform
implementor
hibernate.transaction.factory_class
the factory to use for instantiating Transactions.
(Defaults to JdbcTransactionFactory.)
hibernate.query.substitutions query language token substitutions
