Keycloak, Spring & Vaadin Demo

Vaadin demo backed by Spring Boot (embedded Tomcat) and Keycloak.

General

A showcase on how a Vaadin application can be setup using Gradle, Spring Boot and secured with Keycloak. It is based on security-sample-shared.

The main purpose of this demo is to understand the full build and configuration process to allow the different technologies to work together.

Dependencies

This demo has been tested with following dependencies:

• JDK 8
• Docker >= 17.03.1-ce
• docker-compose >= 1.11.2

!! NOTE !!

The public-access branch demonstrates how the setup can be configured to have a partially public application. In other words, parts of the application are accesible anonymously while other parts required a fully authenticated user.
