The mediator pattern implementing on Java Spring Boot

A lightweight, annotation‐driven Mediator pattern implementation for Spring Boot that decouples request objects from their handlers and centralizes the dispatch logic.

Features

• Annotation-based configuration: Enable the mediator with a single annotation.

• Generic request/response support: Send commands and queries with typed responses.

• Automatic handler registration: All your RequestHandler beans are discovered and wired up.

• Spring Boot starter–style integration: Plug into any existing Spring Boot app.
