This is a collection of small and focused instances - each covering a single and well defined approach in the area of the java application development grouped by modeules. Each module is supposed to provide a separate simple instance. In this project each module presents a small simple instance of the querying approaches and technologies for the spring-boot restful service. A strong focus of these is, of course, the different test approaches of the spring-boot RESTful API.
