Class SpringEventSourcedEntityLookup

java.lang.Object

org.axonframework.extension.spring.config.SpringEventSourcedEntityLookup

All Implemented Interfaces:

org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor

@Internal
public class SpringEventSourcedEntityLookup
extends Object
implements org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor

A BeanDefinitionRegistryPostProcessor implementation that scans for Entity types and registers a configurer for each Entity found.

Polymorphic entity hierarchies whose abstract parent lists its subtypes through EventSourced.concreteTypes() are never registered as a BeanDefinition by Spring's own component scan (abstract classes are not candidate components), so they cannot be found through ListableBeanFactory.getBeanNamesForAnnotation(Class). To support that documented pattern, this class additionally runs its own classpath scan (see #findAbstractEntityRoots()) across the given basePackages, independent of Spring's bean registry, to locate those abstract roots directly.

Since:

4.6.0
