Code coverage for functional tests

Question

I have a Java RESTful API. I use REST Assured for my functional tests on each endpoint.
Is there a way to get the code coverage for the classes/methods used behind the scene (controllers, services, DAOs/repositories, etc.) when REST Assured (or any similar tool) makes calls to the API? (I guess the API should be started with some agent or something that reports what happens until it is stopped?).

• ElementCR: You could try using attribute tags above your methods and have Maven evaluate your code coverage.

I ended up using JaCoCo (Java agent and Maven plugin) with SonarQube

EDIT after Sikandar's comment:
In my case it's a Spring Boot app so when I run the jar file I add the option
-javaagent:/myapp/lib/jacoco.agent-0.7.9.jar=destfile=/myapp/coverage-reports/jacoco-at.exec
Reports are generated when the app is stopped. Then I configured SonarQube to use the file /myapp/coverage-reports/jacoco-at.exec for its analysis

• Sikandar: Can you share the plugin details you added for getting the code coverage. I am trying to get the same using jmeter functional testing.
• Maxime Laval: @Sikandar I added more details in my answer.
