Class CciDaoSupport

java.lang.Object

org.springframework.dao.support.DaoSupport

org.springframework.jca.cci.core.support.CciDaoSupport

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

public abstract class CciDaoSupport
extends DaoSupport

Convenient super class for CCI-based data access objects.

Requires a ConnectionFactory to be set, providing a CciTemplate based on it to subclasses through the getCciTemplate() method.

This base class is mainly intended for CciTemplate usage but can also be used when working with a Connection directly or when using org.springframework.jca.cci.object classes.

Since:

1.2

Method Detail

setConnectionFactory

public final void setConnectionFactory(ConnectionFactory connectionFactory)

Set the ConnectionFactory to be used by this DAO.

createCciTemplate

protected CciTemplate createCciTemplate(ConnectionFactory connectionFactory)

Create a CciTemplate for the given ConnectionFactory. Only invoked if populating the DAO with a ConnectionFactory reference!

Can be overridden in subclasses to provide a CciTemplate instance with different configuration, or a custom CciTemplate subclass.

Parameters:

connectionFactory - the CCI ConnectionFactory to create a CciTemplate for

Returns:

the new CciTemplate instance

See Also:

setConnectionFactory(javax.resource.cci.ConnectionFactory)

getConnectionFactory

public final ConnectionFactory getConnectionFactory()

Return the ConnectionFactory used by this DAO.

setCciTemplate

public final void setCciTemplate(CciTemplate cciTemplate)

Set the CciTemplate for this DAO explicitly, as an alternative to specifying a ConnectionFactory.

getCciTemplate

public final CciTemplate getCciTemplate()

Return the CciTemplate for this DAO, pre-initialized with the ConnectionFactory or set explicitly.

checkDaoConfig

protected final void checkDaoConfig()

Description copied from class: DaoSupport

Abstract subclasses must override this to check their configuration.

Implementors should be marked as final if concrete subclasses are not supposed to override this template method themselves.

Specified by:

checkDaoConfig in class DaoSupport

getCciTemplate

protected final CciTemplate getCciTemplate(ConnectionSpec connectionSpec)

Obtain a CciTemplate derived from the main template instance, inheriting the ConnectionFactory and other settings but overriding the ConnectionSpec used for obtaining Connections.

Parameters:

connectionSpec - the CCI ConnectionSpec that the returned template instance is supposed to obtain Connections for

Returns:

the derived template instance

See Also:

CciTemplate.getDerivedTemplate(javax.resource.cci.ConnectionSpec)

getConnection

protected final Connection getConnection()
                                  throws CannotGetCciConnectionException

Get a CCI Connection, either from the current transaction or a new one.

Returns:

the CCI Connection

Throws:

CannotGetCciConnectionException - if the attempt to get a Connection failed

See Also:

ConnectionFactoryUtils.getConnection(javax.resource.cci.ConnectionFactory)

releaseConnection

protected final void releaseConnection(Connection con)

Close the given CCI Connection, created via this bean's ConnectionFactory, if it isn't bound to the thread.

Parameters:

con - Connection to close

ConnectionFactoryUtils.releaseConnection(javax.resource.cci.Connection, javax.resource.cci.ConnectionFactory)
