This is just a collection of individual Spring try-outs. The goal is to have basic understanding of several aspects of Spring - mainly those relevant for web development. Those aspects can be found e.g. at https://start.spring.io/
In order to gain deeper understanding, the projects should not use the Spring Boot stuff, but the basic Spring stuff.
All projects have corresponding README.md files with further infos.
It is not possible to just "mvn test" the whole project via the "parent" (building works, though). Plz look into the sub-project README.mds to find out, who to test it.
