Spark makes fewer assumptions than the other microframeworks introduced in this short series, and is also the most lightweight of the three stacks. Spark makes pure simplicity of request handling, and it supports a variety of view templates. In Part 1 you set up a Spark project in your Eclipse development environment, loaded some dependencies via Maven, and learned Spark programming basics with a simple example. Now we'll extend the Spark Person application, adding persistence and other capabilities that you would expect from a production-ready web app.
