Class ReactiveHandlersBeanPostProcessor

java.lang.Object
dk.cloudcreate.essentials.reactive.spring.ReactiveHandlersBeanPostProcessor
All Implemented Interfaces:
org.springframework.beans.factory.Aware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.config.DestructionAwareBeanPostProcessor, org.springframework.context.ApplicationContextAware
public class ReactiveHandlersBeanPostProcessor extends Object implements org.springframework.beans.factory.config.DestructionAwareBeanPostProcessor, org.springframework.context.ApplicationContextAware
When using Spring or Spring Boot it will be easier to register the EventBus, CommandBus, CommandHandler and EventHandler instances as @Bean or @Component and automatically have the CommandHandler beans registered as with the single CommandBus bean and the EventHandler beans registered as subscribers with one or more EventBus beans.
All you need to do is to add a @Bean of type ReactiveHandlersBeanPostProcessor which: Registers CommandHandler or EventHandler's in the application context with the single EventBus's and CommandBus defined in the application context.
EventHandler's are registered as synchronous event handler's (EventBus.addSyncSubscriber(EventHandler)) unless it's annotated with the AsyncEventHandler annotation, in which case it's registered as an asynchronous event handler (EventBus.addAsyncSubscriber(EventHandler)
