All Implemented Interfaces:

Snapshotter, org.springframework.beans.factory.Aware, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware

public class SpringAggregateSnapshotter
extends AggregateSnapshotter
implements org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware

Implementation of the AggregateSnapshotter that eases the configuration when used within a Spring Application Context. It will automatically detect a Transaction Manager and Aggregate Factories.

The only mandatory properties to set is AbstractSnapshotter.setEventStore(org.axonframework.eventstore.SnapshotEventStore). In most cases, you should also provide an executor, as the default will execute snapshotter tasks in the calling thread.

Method Detail

setTransactionManager

public void setTransactionManager(org.springframework.transaction.PlatformTransactionManager transactionManager)

Sets the transaction manager to manager underlying transaction with. If none is provided, an attempt is made to auto detect is from the application context. If a single transaction manager is found, it is used to manage transactions. Of none or more than one is found, they are ignored.

Parameters:

transactionManager - the transaction manager managing underlying transactions

setTransactionDefinition

public void setTransactionDefinition(org.springframework.transaction.TransactionDefinition transactionDefinition)

Optionally sets the transaction definition to use. By default, uses the application context's default transaction semantics (see DefaultTransactionDefinition).

Parameters:

transactionDefinition - the transaction definition to use

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

Exception

setAggregateFactories

public void setAggregateFactories(List<AggregateFactory<?>> aggregateFactories)

Optionally sets the aggregate factories to use. By default, this implementation will auto detect available factories from the application context. Configuring them using this method will prevent auto detection.

Overrides:

setAggregateFactories in class AggregateSnapshotter

Parameters:

aggregateFactories - The list of aggregate factories creating the aggregates to store.

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException
