GOTO Academy is the official partner of VMware Spring and the exclusive provider of public Spring certification courses in the Netherlands.

Spring: Core Training is our 4-day flagship Spring Framework masterclass. In this masterclass, you will build a Spring-powered Java application that demonstrates the Spring Framework and other Spring technologies such as Spring Boot, Spring Data, AOP and Spring Security in an intensely productive, hands-on setting.

A masterclass that is highly interactive, intensive and hands-on, led by one of our experienced trainers. The focus of this course is not simply to explain Spring features and how to use them, but also on the fundamental architectural issues. It is important to know how to use certain parts of a framework, but it is even more important to be able to decide when to use them.

Why should you attend?

Highly experienced trainers who still work as developers themselves.
Tips, tricks and real-world examples in addition to the official course materials.
Certification courses that match the exam topics
Gain real skills that you can start using in your Spring project immediately.

** This masterclass is approximately 40% theory and 60% exercises. All labs are supervised with the trainer on-hand to provide answers to individual questions and provide coaching.

Are there any prerequisites?

We assume that participants have a good understanding of the core Java APIs, as well as a basic knowledge of general concepts like JavaEE APIs such as JTA and the Servlet API. As we cover object-relational mapping technologies (ORM) we also assume basic knowledge of ORM concepts and JPA. The masterclass is hands-on. Developers are expected to bring their own laptop.
