Working with Grails 3 Controllers and Services

In this video course, expert Java trainer and consultant Ken Kousen uses a more complete domain model in Grails 3 to show how the static scaffolding works with the fields plugin to build a complete set of web pages for multiple tables. From there, he dives into the details of the generated view pages, which use Grails 3 custom tags and data exposed at different scopes, including flash scope. Finally, he reviews transactional services and dependency injection of service beans, and reveals how to access JSON data through a REST controller.
