Class CciTemplate

java.lang.Object

org.springframework.jca.cci.core.CciTemplate

All Implemented Interfaces:

CciOperations

Deprecated.

as of 5.3, in favor of specific data access APIs (or native CCI usage if there is no alternative)

@Deprecated
public class CciTemplate
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()

Deprecated.

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)

Deprecated.

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

Parameters:

connectionFactory - the JCA ConnectionFactory to obtain Connections from

CciTemplate

public CciTemplate(ConnectionFactory connectionFactory,
                   @Nullable
                   ConnectionSpec connectionSpec)

Deprecated.

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

Parameters:

connectionFactory - the JCA ConnectionFactory to obtain Connections from

connectionSpec - the CCI ConnectionSpec to obtain Connections for (may be null)

Method Detail

setConnectionFactory

public void setConnectionFactory(@Nullable
                                 ConnectionFactory connectionFactory)

Deprecated.

Set the CCI ConnectionFactory to obtain Connections from.

getConnectionFactory

@Nullable
public ConnectionFactory getConnectionFactory()

Deprecated.

Return the CCI ConnectionFactory used by this template.

setConnectionSpec

public void setConnectionSpec(@Nullable
                              ConnectionSpec connectionSpec)

Deprecated.

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

getConnectionSpec

@Nullable
public ConnectionSpec getConnectionSpec()

Deprecated.

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

setOutputRecordCreator

public void setOutputRecordCreator(@Nullable
                                   RecordCreator creator)

Deprecated.

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

@Nullable
public RecordCreator getOutputRecordCreator()

Deprecated.

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

afterPropertiesSet

public void afterPropertiesSet()

Deprecated.

getDerivedTemplate

public CciTemplate getDerivedTemplate(ConnectionSpec connectionSpec)

Deprecated.

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

Deprecated.

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

@Nullable
public <T> T execute(InteractionCallback<T> action)
                        throws DataAccessException

Deprecated.

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
