spring-simple-api

The point of this project is to design a small spring rest api that communicates with a mongodb app, using json to do classic CRUD operations.

Building/Testing/Compiling

To simply run the application :

mvn spring-boot:run

If you want to run the tests :

mvn test

For load tests with gatling, run :

./gatling_tests.sh

This will start the app and then launch the load tests on it. You'll see some result in your console, but you can go check out the graphs in target/gatling afterwards and open the index.html for nice looking graphs (Can also be done using mvn clean install)

To launch all tests and loading tests as well :

mvn verify

To generate the checkstyle report (Also see the intellij integration plugin) :

mvn checkstyle:check

To generate all jars and launch all tests :

mvn clean install

Security

Api authentication is done using spring security and JWT. To authenticate, you need to do a POST request on the /api/login endpoint and give it the following a request body :

{"username":"admin","password":"password"}

Example curl request :

curl -i -X POST \
  http://localhost:8080/api/login \
  -H 'cache-control: no-cache' \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"password"}'

Then you get an authorization bearer in headers, you can copy it and do another request with its value as a header :

curl -i -X GET \
  http://localhost:8080/api/supervisors \
  -H 'authorization: eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTQ5NjE0Nzk5NX0.U0bW5-_QmwBpVnf0bEK1Tg6LwF5QgSnb8ekYXygh-Zxor-ujm_btAMPz5Exw4FVGg2-oQNJAQnl-B2peuG8nlA' \
  -H 'cache-control: no-cache' \
  -H "Accept: application/json" \
  -H "Content-Type: application/json"

All /api/supervisors require authentication as an example.

Architecture

There is just a mongodb docker container and a springboot app to run. You can define a mongodb database manually or execute scripts/CreateDockerDatabases_x64. Then you can start or stop it using docker cli.

Technologies used

• API : Spring MVC app (Java) with springboot
• Persistence : Mongodb NoSQL Database (Document oriented)

Documentation

When you run the api, you can access the address localhost:8080/, it will redirect you to the swagger-ui. From there you'll have access to all routes and be able to test them.
