DefaultConfigurer (Axon Framework 3.1.1 API)

java.lang.Object
- org.axonframework.config.DefaultConfigurer

All Implemented Interfaces:

Configurer
```
public class DefaultConfigurer
extends Object
implements Configurer
```
Entry point of the Axon Configuration API. It implements the Configurer interface, providing access to the methods to configure the default Axon components.
Using defaultConfiguration(), you will get a Configurer instance with default components configured. You will need to register your Aggregates (using configureAggregate(AggregateConfiguration) and provide a repository implementation for each of them, or if you wish to use event sourcing, register your aggregates through Configurer.configureAggregate(Class) and configure an Event Store (Configurer.configureEventStore(Function) or configureEmbeddedEventStore(Function)).
Use buildConfiguration() to build the configuration, which provides access to the configured building blocks, such as the CommandBus and EventBus.
Note that this Configurer implementation is not thread-safe.

    Specified by:
    
    configureMessageMonitor in interface Configurer
    
    Parameters:
    
    builder - The MessageMonitor builder function
