Going springless: no more magic!

Working with Spring Boot (but also working with JEE/Jakarta EE) can be a joyful experience. Within minutes you can create a  new RESTfull webservice  to which you can quickly and easily add circuit breakers, distributed tracing, security, database access, accessing other microservices, fallbacks, retries, service discovery, configuration management, many other things and of course you can use the great Spring DI framework.

Java REST services, search for smallest footprint

For my private projects I have rented a virtual Linux server in the cloud.
Since this server has a limited amount of memory I would like my microservices to be as small as possible.
Most of my microservers expose a REST API, so I decided to test some different implementations to implement a REST service.
