Summary

In this chapter, we learned how to implement both blocking and non-blocking endpoints in Quarkus using RESTEasy Reactive. We also implemented the complete business logic and HTTP API for our application. We started by developing the business logic for the task manager in different service classes. Then, we implemented the JAX-RS endpoints in resource controller classes that receive these services via dependency injection. We also learned how to map Java exceptions to HTTP responses to be able to provide more accurate response status codes and how to fully customize the response.

You should now be able to implement HTTP and REST APIs in Quarkus. In the next chapter, we’ll see how to secure the application using JWT. We’ll implement JWT authentication and authorization and protect the endpoints we just developed.
