# Spring Boot sample projects

[![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)

The goal of the project is to show simple demos of using [Spring Boot](https://spring.io/projects/spring-boot) with different technologies.

The examples are limited to Maven and JVM >= 17 ([Java](https://www.java.com/de/) and [Kotlin](https://kotlinlang.org/)). 

Specifically used technologies are described below in the table.

| Demo                                             | Technologies                                | Content                                                                | Build status                                                                                                                                                                                                    |
