Tutorial: Spring Boot + Spring Data JPA + Java 16 (Part III, enums and lists)

In part I and II of this JPA series, I showed how to get started with Spring Boot, Spring Data JPA, and create your first Entity and Repository. In this part, I'm adding a few details that bring the code closer to what I need: How to return (and test) a list of items from a REST endpoint, and how to use Enum structure with Spring Boot Data JPA. In addition, I'll be bringing more people along from Middle Earth as test data.

Timecodes:
0:00 - Intro
1:03 - What we're going to do?
1:00 - Change the test first
2:32 - Run the test and see it fail
3:15 - Fix the implementation - return a list of people
6:11 - Run the test to see it working
9:15 - Introduce test data type with help of an Enum
11:00 - Annotating enum with Spring Boot/Spring Data support
13:10 - Update the entity object essentials (equals, toString,hashCode)
14:20 - Fix LoadDatabase part
17:05 - Check that everything still works
17:40 - Run the integration test to see all still works

The Git repository that contains the code I write here is at https://github.com/crystoll/testdatamaker - you can clone it and study/play with it. Note that the head of the repository might be farther than the video you are watching, so you can always checkout individual commits to get to the level you want to study.
