You’ve already learned so much about Spring Boot in the last three chapters. You now have a solid foundation in Spring Boot, having already seen various features of the framework and several common tasks that you need to perform on daily basis. You’ve also learned how to communicate and use a database in a Spring Boot application.
In this chapter, you’ll explore two major concepts of Spring Boot: the Spring Boot autoconfiguration and Spring Boot actuator. You’ll learn various building blocks of Spring Boot autoconfiguration and explore how it works in an application.

You’ll then explore the Spring Boot actuator, which lets you monitor your application health and let you interact with it.
