In this chapter, we reviewed some of the most common projects available in Spring, along with a brief explanation and use case for each of them. We also looked at the Spring Reactor project and the features associated with it, which can be implemented using Spring Data. We then looked at writing RESTful web services.

With all of the knowledge that you have acquired, it's time to dive into the subsequent chapters to review some architectural styles and learn how to implement them using the Spring Framework.
