I'm a beginner with spring boot. I'm involved in the beginning of a project where we would build rest services using spring boot. Could you please advise the recommended directory structure to follow when building a project that will just expose rest services?
You do not need to do anything special to start. Start with a normal java project, either maven or gradle or IDE project layout with starter dependency.
You need just one main class, as per guide here and rest...
There is no constrained package structure. Actual structure will be driven by your requirement/whim and the directory structure is laid by build-tool / IDE
You can follow same structure that you might be following for a Spring MVC application.
You can follow either way
A project is divided into layers:
for example: DDD style
- Service layer : service package contains service classes
- DAO/REPO layer : dao package containing dao classes
- Entity layers
orany layer structure suitable to your problem for which you are writing problem.
A project divided into modules or functionalities or features and A module is divided into layers like above
I prefer the second, because it follows Business context. Think in terms of concepts.
What you do is dependent upon how you see the project. It is your code organization skills.
