Summary

In this chapter, we created our first Spring application. We saw Spring Initializr, the amazing tool that helps developers create the application skeleton.

We looked at how Spring works under the hood and how the framework got configured with a couple of annotations. Now, we have a basic knowledge of the Spring Bootstrap functions, and we can understand the Dependency Injection and component scan features present in the framework.

This knowledge is the basis for the next chapters, and now we are ready to start to work with more advanced features, such as persistence. Here we go. See you in the next chapter.
