jflu | project aims at seamlessly creating events

All librairies are available on Maven Central. For example, jflu-subscriber-rabbitmq can be included in your dependencies like this (Gradle example):. Most of the default implementations can be extended by composition or inheritance.
base classes to work with events, producers and subscribers;
structures and how they must be un/marshalled from/to JSON;
all interfaces that require a specific implementation based on your own system architecture and technologies.
You can register be.looorent.jflu.hibernate.EntityListener as an Hibernate session-scoped interceptor. EntityListener requires an instance of EventPublisher. An environment variable must be specified to set the events' emitter: JFLU_EMITTER. If no JFLU_EMITTER environment variable is set, [not emitter set] will be used as the default emitter. Use this JAR if you want to generate events whenever a Spring MVC controller is called.
Create a subclass that provides an EventPublisher supplier. class FluEntityInterceptor extends EntityListener { FluEntityInterceptor() { super(() -> new YourEventPublisher()) } }
Register this provider as an Hibernate session-scoped interceptor. hibernate.ejb.interceptor.session_scoped: FluEntityInterceptor
For instance, register an instance of WebMvcConfigurerAdapter (which requires an implementation of EventPublisher) as a Spring MVC interceptor handler. An environment variable must be specified to set the events' emitter: JFLU_EMITTER. If no JFLU_EMITTER environment variable is set, [not emitter set] will be used as the default emitter.
To initialize an instance of RabbitMQEventPublisher, several properties must be provided:.
rabbitmq.username
rabbitmq.password
rabbitmq.virtual-host
rabbitmq.host
rabbitmq.port
rabbitmq.exchange-name
rabbitmq.exchange-durable
rabbitmq.wait-for-connection
To initialize the subscription configuration, several properties must be provided (they are read from environment variables automatically):.
rabbitmq.username
rabbitmq.password
rabbitmq.host
rabbitmq.port
rabbitmq.virtual-host
rabbitmq.exchange-name
rabbitmq.queue-name
rabbitmq.prefetch-size
rabbitmq.queue-durable
rabbitmq.wait-for-connection
