org.springframework.jca.cci.core
Class CciTemplate

java.lang.Object
  org.springframework.jca.cci.core.CciTemplate

All Implemented Interfaces:: CciOperations

public class CciTemplate
extends Object
implements CciOperations
extends Object
implements CciOperations

This is the central class in the CCI core package. It simplifies the use of CCI and helps to avoid common errors. It executes core CCI workflow, leaving application code to provide parameters to CCI and extract results. This class executes EIS queries or updates, catching ResourceExceptions and translating them to the generic exception hierarchy defined in the org.springframework.dao package.

Code using this class can pass in and receive Record instances, or alternatively implement callback interfaces for creating input Records and extracting result objects from output Records (or CCI ResultSets).

Can be used within a service implementation via direct instantiation with a ConnectionFactory reference, or get prepared in an application context and given to services as bean reference. Note: The ConnectionFactory should always be configured as a bean in the application context, in the first case given to the service directly, in the second case to the prepared template.

Since:: 1.2

Constructor Detail

CciTemplate

public CciTemplate()

Construct a new CciTemplate for bean usage.

Note: The ConnectionFactory has to be set before using the instance.

See Also:: setConnectionFactory(javax.resource.cci.ConnectionFactory)

CciTemplate

public CciTemplate(ConnectionFactory connectionFactory)

Construct a new CciTemplate, given a ConnectionFactory to obtain Connections from. Note: This will trigger eager initialization of the exception translator.

Parameters:: connectionFactory - JCA ConnectionFactory to obtain Connections from

CciTemplate

public CciTemplate(ConnectionFactory connectionFactory,
                   ConnectionSpec connectionSpec)

Construct a new CciTemplate, given a ConnectionFactory to obtain Connections from. Note: This will trigger eager initialization of the exception translator.

Parameters:: connectionFactory - JCA ConnectionFactory to obtain Connections from; connectionSpec - the CCI ConnectionSpec to obtain Connections for (may be null)

Method Detail

setConnectionFactory

public void setConnectionFactory(ConnectionFactory connectionFactory)

Set the CCI ConnectionFactory to obtain Connections from.

getConnectionFactory

public ConnectionFactory getConnectionFactory()

Return the CCI ConnectionFactory used by this template.

setConnectionSpec

public void setConnectionSpec(ConnectionSpec connectionSpec)

Set the CCI ConnectionSpec that this template instance is supposed to obtain Connections for.

getConnectionSpec

public ConnectionSpec getConnectionSpec()

Return the CCI ConnectionSpec used by this template, if any.

setOutputRecordCreator

public void setOutputRecordCreator(RecordCreator creator)

Set a RecordCreator that should be used for creating default output Records.

Default is none: When no explicit output Record gets passed into an execute method, CCI's Interaction.execute variant that returns an output Record will be called.

Specify a RecordCreator here if you always need to call CCI's Interaction.execute variant with a passed-in output Record. Unless there is an explicitly specified output Record, CciTemplate will then invoke this RecordCreator to create a default output Record instance.

See Also:: Interaction.execute(javax.resource.cci.InteractionSpec, Record), Interaction.execute(javax.resource.cci.InteractionSpec, Record, Record)

getOutputRecordCreator

public RecordCreator getOutputRecordCreator()

Return a RecordCreator that should be used for creating default output Records.

afterPropertiesSet

public void afterPropertiesSet()

getDerivedTemplate

public CciTemplate getDerivedTemplate(ConnectionSpec connectionSpec)

Parameters:: connectionSpec - the CCI ConnectionSpec that the derived template instance is supposed to obtain Connections for
Returns:: the derived template instance
See Also:: setConnectionSpec(javax.resource.cci.ConnectionSpec)

execute

public Object execute(ConnectionCallback action)
               throws DataAccessException

Description copied from interface: CciOperations

Execute a request on an EIS with CCI, implemented as callback action working on a CCI Connection. This allows for implementing arbitrary data access operations, within Spring's managed CCI environment: that is, participating in Spring-managed transactions and converting JCA ResourceExceptions into Spring's DataAccessException hierarchy.

The callback action can return a result object, for example a domain object or a collection of domain objects.

Specified by:: execute in interface CciOperations

Parameters:: action - the callback object that specifies the action
Returns:: the result object returned by the action, if any
Throws:: DataAccessException - if there is any problem

execute

public Object execute(InteractionCallback action)
               throws DataAccessException

Description copied from interface: CciOperations

Execute a request on an EIS with CCI, implemented as callback action working on a CCI Interaction. This allows for implementing arbitrary data access operations on a single Interaction, within Spring's managed CCI environment: that is, participating in Spring-managed transactions and converting JCA ResourceExceptions into Spring's DataAccessException hierarchy.

The callback action can return a result object, for example a domain object or a collection of domain objects.

Specified by:: execute in interface CciOperations

Parameters:: action - the callback object that specifies the action
Returns:: the result object returned by the action, if any
Throws:: DataAccessException - if there is any problem
