public class SpringAggregateSnapshotter extends AggregateSnapshotter implements org.springframework.context.ApplicationContextAware
AggregateSnapshotter
, this implementation lazily retrieves AggregateFactories from the Application
Context when snapshot requests are made.
Instead of configuring directly, consider using the SpringAggregateSnapshotterFactoryBean
, which
configures this class using values available in the application context.

. The
AggregateFactory
instances are lazily retrieved by the ApplicationContext
.
Will assert that the EventStore
, ParameterResolverFactory
and HandlerDefinition
are not
null
, and will throw an AxonConfigurationException
if any of them is null
.

SpringAggregateSnapshotter
. The AggregateFactory
instances are lazily retrieved by the ApplicationContext
.
The Executor
is defaulted to an DirectExecutor.INSTANCE
and the
TransactionManager
defaults to a NoTransactionManager
.
Additionally, this Builder has convenience functions to default the ParameterResolverFactory
and
HandlerDefinition
based on instances of these available on the classpath in case these are not provided
(respectively AggregateSnapshotter.Builder.buildParameterResolverFactory()
and AggregateSnapshotter.Builder.buildHandlerDefinition()
).
Upon instantiation of a AggregateSnapshotter
, it is recommended to use these function to set those
fields.
The EventStore
is a hard requirement and as such should be provided.

Sublasses may override this method to enhance how AggregateFactories are retrieved. They may choose to
AggregateSnapshotter.registerAggregateFactory(AggregateFactory)
if it hasn't been found using this implementation.
