Summary
In this chapter, we looked at the main concepts of Spring Framework. We understood the main modules of the framework and how these modules can help developers to build applications in different kinds of architecture, such as messaging applications, REST APIs, and web portals.
We also spent some time preparing our development environment by installing essential tools, such as Java JDK, Maven, and IDE. This was a critical step to take before we continue to the next chapters.
We used Docker to help us to set up a development environment, such as containers for databases and delivery for our application in Docker images. We installed Docker and looked at the main commands for managing containers, networks, and volumes.
In the next chapter, we will create our first Spring application and put it into practice!
