Introduction to Spring Boot 2 – 3 Days

Course Description – Introduction to Spring Boot 2

As the Spring framework has grown, creating and configuring Spring applications has become more and more complex. Spring Boot takes an “opinionated” view of an application (via intelligent defaults) that minimizes configuration and boilerplate Spring code. Spring Boot makes it easier to use Spring’s many frameworks, and adds advanced capabilities such as health monitoring.

This course introduces Spring Boot from the ground up, including overviews of building blocks such as maven. It covers the key features and capabilities of Spring Boot, and teaches experienced Spring developers the skills they need to use Spring Boot productively.

This course covers Spring Boot 2 and Spring 5 – the current releases of these frameworks.

The standard platform does all labs with the Eclipse IDE, and the lab instructions include detailed directions for setting up and using it. The course can be made available for all major development environments, including IBM RAD and IntelliJ.
