Spring Boot

In the previous chapter, you looked at messaging. You used Spring to configure the message senders and listeners, and you did explicit wiring of beans and required infrastructure in Spring. So far, so good. Now how can you make aspects even simpler? You'll look at Spring Boot in this chapter, which makes use of an opinionated view of the Spring platform and many third-party Java libraries so that it is easy and straightforward to create stand-alone, production-grade, Spring-based applications that you can "just run." Since Boot follows many conventions and usage patterns followed by developers, which they have been leveraging while using Spring and other third-party libraries, most Spring Boot applications need very little Spring configuration. You will use Spring Boot to develop the few samples relevant to the discussion in this chapter. Again, the intention is not to cover Spring Boot in detail; that is outside the scope of this chapter. Readers familiar with Java or Spring should have no problem getting started by visiting the Spring Boot home page. I will spend time on very essential tools required for the discussion so that I don't deviate from the intention of this book, which is explaining practical microservices. However, by the time you start looking at the code samples in later chapters, you should be familiar with the basic building block code constructs.
