Summary

With this, we have reached the end of this chapter. Let’s have a recap of the valuable things you have learned. You have learned the fundamentals of Spring Boot, its architecture, and the basics of REST. You have also learned how to use Spring Initializr to create your own Spring Boot project.

Dependency injection allows objects or classes to accept other dependencies that can implement different classes without writing them again. Annotations define the different types of beans; they are simply a form of metadata that marks our code to provide information.

And finally, beans are objects that form the backbone of an application managed by the Spring IoC container.

In the next chapter, we will be learning how to set up a database and use Spring Data JPA.
