Content
Intention of this Book is to expand your knowledge about how to work with Database within Spring Boot by using: Finder Methods, JPQL and Native Queries.
Standalone Tutorials
The core of this Book are standalone tutorials that explain different functionalities of Spring Boot.
Each tutorial contains minimum amount of code needed to explain specific functionality.
And also minimum amount of encompassing text that explains related theory and different parts of the code.
This approach allows students to grasp presented concepts in a very fast and efficient manner.
Full code, which can also be downloaded from GitHub, prevents any time being wasted trying to make the code work.
Simple examples allow for full understanding of the functionality without any unnecessary distractions.
