Opleiding: Building REST APIs with Spring Boot (EN/NL/FR)

During this training, we will learn how to use the Spring Boot Framework for building REST APIs. In this three-day ABIS course, the participant will gain knowledge on how to create Java endpoints for API calls.

Spring is a Java framework for building enterprise solutions. Spring will enable you to focus on your business problem rather than the plumbing that connects components and systems and will make your code easier to test. Spring Boot will even simplify things further.

In this course you will

• learn how you can build and test REST APIs using Spring Boot
• use a controller for creating API endpoints
• get a basic introduction in Spring Security
