Summary

This chapter was all about jumping into Spring Boot 3.0. Think of Spring Boot as a tool that makes working with Java a whole lot easier, especially when working on big, complex projects. We saw how it helps speed up setting up projects and eases the process of quickly handling big tasks.

Here’s what we learned:

• Quick setup: Spring Boot makes it easy to start a new project, allowing one to focus on developing the fun stuff with minimal fuss
• Microservices: Simply put, this is a fancy term for breaking up a big project(s) into small parts, so things are easier to manage
• User-friendly: Spring Boot’s auto-configuration feature helps the developers to bypass manual setup processes
• Plenty of tools: It is like a Swiss knife for programming with tools for managing databases and security
• Cloud-ready: It is great to work with projects running in the cloud
• Testing made simple: Testing your work is super important and Spring Boot makes it simpler
• Community and updates: There are so many users out there working on Spring Boot and making it better – so it just keeps getting better

Here onward, in the next chapter, we will learn about microservice architectures, DDD, CQRS, and Event Sourcing. We will learn why a microservice design pattern is important and how to choose the correct one for our projects.
