Microservices Deployment Cookbook

Writing REST APIs with SparkJava

In the previous recipes, we saw how to create a microservice using various frameworks such as Spring Boot, WildFly Swarm, and Dropwizard. This recipe is going to be a little different for the fact that we are going to see how to create a self-managed RESTful API using a framework called SparkJava. Not to be confused with Apache Spark, the SparkJava framework claims to be a micro-framework for building web applications. Their HTTP API was inspired by Ruby's Sinatra framework. It is so simple that bringing up an HTTP GET API requires fewer than ten lines of code. Owing to this, SparkJava is something that could be considered when you would like to quickly build HTTP-based microservices.
