Method Details

connection

CommonSharedBuilder connection()

Signifies that the connection from the original session should be used to create the new session. Implies that the overall "transaction context" should be shared as well.

Returns:

this, for method chaining

interceptor

CommonSharedBuilder interceptor()

Signifies the interceptor from the original session should be used to create the new session.

Returns:

this, for method chaining

statementInspector

CommonSharedBuilder statementInspector()

Signifies that the SQL statement inspector from the original session should be used to create the new session.

Returns:

this, for method chaining

noStatementInspector

CommonSharedBuilder noStatementInspector()

Description copied from interface: CommonBuilder

Signifies that no SQL statement inspector should be used.

By default, if no inspector is explicitly specified, the inspector associated with the SessionFactory, if one, is inherited by the new session.

Specified by:

noStatementInspector in interface CommonBuilder

Returns:

this, for method chaining

interceptor

CommonSharedBuilder interceptor(Interceptor interceptor)

Description copied from interface: CommonBuilder

Adds a specific interceptor to the session options.

Specified by:

interceptor in interface CommonBuilder

Parameters:

interceptor - The interceptor to use.

Returns:

this, for method chaining

noInterceptor

CommonSharedBuilder noInterceptor()

Description copied from interface: CommonBuilder

Specifies that no Interceptor should be used. This indicates to ignore both (if either) the interceptor and session-scoped interceptor associated with the SessionFactory

Specified by:

noInterceptor in interface CommonBuilder

Returns:

this, for method chaining

noSessionInterceptorCreation

CommonSharedBuilder noSessionInterceptorCreation()

Description copied from interface: CommonBuilder

Specifies that no session-scoped interceptor should be used for the session. If the SessionFactory has a configured interceptor, it will still be used.

Specified by:

noSessionInterceptorCreation in interface CommonBuilder

Returns:

this, for method chaining

See Also:

• CommonBuilder.noInterceptor()

statementInspector

CommonSharedBuilder statementInspector(UnaryOperator<String> operator)

Description copied from interface: CommonBuilder

Applies the given statement inspection function to the session.

Specified by:

statementInspector in interface CommonBuilder

Parameters:

operator - An operator which accepts a SQL string, returning a processed SQL string to be used by Hibernate instead. The operator may simply (and usually) return the original SQL.

Returns:

this, for method chaining

readOnly

CommonSharedBuilder readOnly(boolean readOnly)

Description copied from interface: CommonBuilder

Specify a read-only mode for the session. If a session is created in read-only mode, then Connection.setReadOnly(boolean) is called when a JDBC connection is obtained.

Furthermore, if read/write replication is in use, then:

• a read-only session will connect to a read-only replica, but
• a non-read-only session will connect to a writable replica.

When read/write replication is in use, it's strongly recommended that the session be created with the initial cache-mode set to CacheMode.GET, to avoid writing stale data read from a read-only replica to the second-level cache. Hibernate cannot possibly guarantee that data read from a read-only replica is up to date.

When read/write replication is in use, it's possible that an item read from the second-level cache might refer to data which does not yet exist in the read-only replica. In this situation, an exception occurs when the association is fetched. To completely avoid this possibility, the initial cache-mode must be set to CacheMode.IGNORE. However, it's also usually possible to structure data access code in a way which eliminates this possibility.

try (var readOnlySession =
		sessionFactory.withOptions()
			.readOnly(true)
			.initialCacheMode(CacheMode.IGNORE)
			.openSession()) {
	...
}

If a session is created in read-only mode, then it cannot be changed to read-write mode, and any call to Session.setDefaultReadOnly(boolean) with fail. On the other hand, if a session is created in read-write mode, then it may later be switched to read-only mode, but all database access is directed to the writable replica.

Specified by:

readOnly in interface CommonBuilder

Returns:

this, for method chaining

• MultiTenantConnectionProvider.releaseReadOnlyConnection(Object, Connection)

initialCacheMode

CommonSharedBuilder initialCacheMode(CacheMode cacheMode)

Description copied from interface: CommonBuilder

Specify the initial CacheMode for the session.

Specified by:

initialCacheMode in interface CommonBuilder

Returns:

this, for method chaining

See Also:

• SharedSessionContract.getCacheMode()

tenantIdentifier

CommonSharedBuilder tenantIdentifier(Object tenantIdentifier)

Description copied from interface: CommonBuilder

Specify the tenant identifier to be associated with the opened session.

try (var session = sessionFactory.withOptions()
		.tenantIdentifier(tenantId)
		.openSession()) {
	...
}

Specified by:

tenantIdentifier in interface CommonBuilder

Parameters:

tenantIdentifier - The tenant identifier.

Returns:

this, for method chaining

connection

CommonBuilder connection(Connection connection)

Description copied from interface: CommonBuilder

Adds a specific connection to be used to the session options.

Specified by:

connection in interface CommonBuilder

Parameters:

connection - The connection to use.

Returns:

this, for method chaining

connectionHandling

CommonSharedBuilder connectionHandling(ConnectionAcquisitionMode acquisitionMode,
 ConnectionReleaseMode releaseMode)

Description copied from interface: CommonBuilder

Specifies the connection handling modes for the session.

Specified by:

connectionHandling in interface CommonBuilder

Returns:

this, for method chaining

jdbcTimeZone

CommonSharedBuilder jdbcTimeZone(TimeZone timeZone)

Description copied from interface: CommonBuilder

Specify the JDBC time zone to use for the session.

Specified by:

jdbcTimeZone in interface CommonBuilder

Returns:

this, for method chaining
