Questions Management – API Question Service – Build API add new question using Spring WebFlux

Check out the full series of Questions Management tutorial here.

In the previous tutorial, we prepared all the necessary configurations to be able to build API add new question: an object containing all the information of a question CompositeQuestion, including a Question, a Category, and an Option; a CompositeQuestionService interface with CompositeQuestionServiceImpl implementation is responsible for handling the Composite Question Service, an ApiQuestionController that defines the APIs for API Question Service will start with a “/question” and information about the Composite Question Service is configured in the application.properties file. Now, let’s build this API!

To build API add new question, first I will add a new createNewQuestion() method in the CompositeQuestionService interface:

The implementation of this method calls the Composite Question Service in the CompositeQuestionServiceImpl class as follows:

As you can see, here I have used the WebClient object to connect to the Composite Question Service and call the API add a new question of this service with the “/question/add” URI.

Next, I’m going to add a method call to the CompositeQuestionService’s createNewQuestion() method to expose a POST request “/question/add” in ApiQuestionController like this:

At this point, we have completed the API to add new question for API Question Service. Let’s try it.
