Creating Java Microservices

We've seen a lot of theory behind microservice architecture in Chapter 3, Working with Microservices. It's time to do some hands-on practice; we are going to implement our own microservice. This will be a simple REST service, accepting HTTP methods such as GET and POST to retrieve and update entities. There are a couple of choices when developing microservices in Java. In this chapter, we are going to get an overview about two main approaches, probably the most popular will be JEE7, and Spring Boot. We will briefly see how we can code a microservice using JEE JAX-RS. We will also create a microservice running on Spring Boot. In fact, in Chapter 5, Creating Images with Java Applications, we are going to run our Spring Boot microservice from within a Docker container. As we have said in Chapter 3, Working with Microservices, microservices usually...
