Building Microservices with Spring Boot

Developing microservices is not so tedious anymore--thanks to the powerful Spring Boot framework. Spring Boot is a framework for developing production-ready microservices in Java.

This chapter will move from the microservices theory explained in the previous chapters to hands-on practice by reviewing code samples. Here, we will introduce the Spring Boot framework, and explain how Spring Boot can help building RESTful microservices inline with the principles and characteristics discussed in the previous chapter. Finally, some of the features offered by Spring Boot for making the microservices production ready will be reviewed.

At the end of this chapter, you will have learned about the following:

• Setting up the latest Spring development environment
• Developing RESTful services using Spring Framework 5 and Spring Boot
• Building reactive microservices using Spring WebFlux and Spring Messaging
• Securing microservices using Spring Security and OAuth2
• Implementing cross-origin microservices
• Documenting Spring Boot microservices using Swagger
• Spring Boot Actuator for building production-ready microservices
