This post describes how to build a REST service with Spring-Boot that uses Basic-Authentication for several users and that uses the username of the authenticated user to do it’s work. Warning: A service using basic authentication should always use HTTPS as transport protocol, either by running behind a web server proxy or by setting up HTTPS by itself. I’ll cover the latter in a later post.
This might be a setup for a service, where for each user, data is stored in a database, so it not only is necessary to authenticate the user to use the service, but it is also necessary in the service to know which user is accessing the service.
When writing a Spring-Boot application it is possible to use your own custom configuration classes which are injected by spring into your application and which are configured in the application.properties file. There is even support for autocomplete support in the properties file editor in IntelliJ IDEA (I suppose there is something similar in Eclipse or NetBeans, but I haven’t tried that). This post shows how to achieve this.
Basically this is used for auto configuration of Spring-Boot components, but can be used in the Spring-Boot application as well.
Recently I wrote an application based on Vaadin Spring-boot, and when I needed to modify the theme of the application I needed to do some research as how to achieve that. I think that at the time the combination of Vaadin and Spring-boot is still pretty new so that information still must be sought. So in this post I describe the necessary steps.
I use the following versions of different tools:
