Summary

Now, we can effectively write RESTful APIs using the Spring Framework. We learned how to create complex objects using JSON and how we can handle them when creating requests and responses in our API. We know how we can use HTTP verbs and statuses to define the ubiquitous language of our API, to provide a clear communication to the API consumers.
