Simple REST api in Java (String-boot / not reactive)

This project has as objective to have a rest api build on:

• Gradle
• Java 14
• Spring boot 2.3.0-RELEASE
• MySQL (8.0.20)

Using standard rest/web spring-boot strategy, non-reactive.

We will use SQL with JPA. We will use MySQL as database.

What the rest api will stand for?

The rest will have the resource:

/users

Where the endpoints exposed are:

Method	Endpoint	Description
GET	/users	Get all the users
POST	/users	Create a new user
GET	/users/{user_id}	Get specific user data
DELETE	/users/{user_id}	Delete specific user data

Run application

This project has been set to run under docker.

To run the application the Makefile has been set to:

• start: to start the application in docker
• stop: stop and drop the containers
• restart: does stop and start
• logs: display the logs of the deployed docker containers

So, the start action will do:

• gradle build the project to generate the jar
• docker build the image, based on the jar generated on the previous step
• start database and the application, which a dependency from application to the database start, to wait until the database is up and ready for the application

The stop action will do:

• stop the application and database
• destroy the container s for the application and the database

Out-of-scope

It was got out of scope any software to create the database structure, out from mysql setup.

This is to keep this app simple, to not get deeper on other solutions outside of the endpoint exposures.
