Description

Our training focuses on the practical topics of Spring Framework such as how to use Spring REST, HATEOAS and CORS, documenting REST services, serializing and limiting the data passed to the client and more.

We will also cover the use o @Transactional annotation, optimistic transactions, JWT authorization, OAuth2 authorization server, practical usage of reactive programming with WebFlux as well as testing Spring services, Scheduler & Actuator, and deploying to Docker.
After completing the course, a certificate
is issued on the Luxoft Training form
