Spring Boot — Project Structure Practices

In this article, I am going to talk about package structures for Spring Boot applications and give the one I create whenever I started a new project. Proper packaging in a project is important because when the project grows or someone else is assigned to your project, it must be easy to get around different kind of files. For example, when you need a file of type model, you just directly go into the model package and easily find what you are looking for. If you do no have such a structure, it becomes a time-consuming problem in large projects.
