Questions: custom plugin or extension use about pf4j-spring

[decebals]

Sky's the limit when you use PF4J. PF4J is very flexible and powerful. Try to ignore PF4J in first step and think your business like a monolithic application. The use of PF4J comes natural after this.
For example, use an event driven approach, declare an interface MyMessageListener with one method like onMessage(String/Message message). If you want to be notified, implement this interface.
Make this interface an extension point (extends ExtensionPoint). In your message provider (a plugin probably or directly your application) when a new message arrives, use pluginManager.getExtensions(MyMessageListener) to get all listeners and for each listener call onMessage. That is all. It's easy and natural.
For a real life scenario/usage see ta4j/ta4j#411 (comment).
