Spring Boot Thymeleaf Field Validation

This video shows how to add field validation to a Thymeleaf Spring Boot application. We are adding validation constraints to our SpaceShip that we created yesterday. We create a custom validation which applies an error if the SpaceShip starts with a F. Enjoy! :-) Thank you for commenting and asking questions! They all mean a lot to me.
