In this chapter, we explored the concepts related to MVC architecture and how they work. We also discussed the errors that people tend to make when building applications using this architectural style.

Then we reviewed how to create an application using Spring MVC, looking at different tests and how to implement them using features provided by Spring. We also reviewed how to use Thymeleaf with Spring MVC in order to build the UI for a web application. To finish this chapter, we discussed some security concepts, including how to apply them in a Spring MVC application.

In the next chapter, you will learn about event-driven architectures, which are becoming quite popular.
