Overview
This fast-paced instructor-led online course covers Java application development.
During the course, we assemble an eCommerce type Web Application, using Dependency Injection to connect application layers. A Repository Layer maps entity classes to a MySQL database using Spring Data Persistence. A Service Layer contains business logic and a Web Service is implemented as a REST Controller Layer with Spring. HTML User Interfaces to the web service are built with Bootstrap and jQuery AJAX.
