Intro to Spring Boot: Models (Part 1)
Notes
In this lesson we will focus on creating distinct, POJO model objects. POJO stands for "plain, old Java object". We will then move all data operations out of the controller layer and into the model layer. We will use model binding to auto-create model classes on form submission.
Code along with the video using the starter code below. There have been some changes to the codebase since the last video, so you'll want to look at the branch listed below to get those changes.
Some Bootstrap classes we have added to improve the look and feel of our application are: container, form-group, and form-control.
If you haven't already done this in the course of previous class exercises, begin refactoring (improving your code while not adding new features) your CheeseController by creating a models package and creating a Cheese Java class. Use auto-generation (see Intelli-J Tip below) to create a constructor and the relevant getters and setters. Continue refactoring CheeseController and then update your templates to use the newly-created Cheese class instead.
At the end of this lesson, the remove functionality will not work. We will tackle the solution to that problem, as well as how to get the data out of our controller, in the next lesson!

Use right-click and select "Generate" to select among boilerplate code generation options to speed up your program development.
