Trifork Academy is the official training partner of VMware by Broadcom in the Netherlands & exclusive provider of the Spring: Core Masterclass. Learn more from our CTO & Trainer, Joris Kuipers.

In this masterclass, you will build a Spring-powered Java application that demonstrates the Spring Framework & other Spring technologies such as Spring Boot, Spring Data, AOP and Spring Security.

Course Overview

Objectives & Prerequisites

By the end of the course, you should be able to meet the following objectives:

Spring configuration using Java Configuration and Annotations
Aspect oriented programming with Spring
Testing Spring applications using JUnit 5
Spring Data Access – JDBC, JPA and Spring Data
Spring Transaction Management
Simplifying application development with Spring Boot
Spring Boot auto-configuration, starters and properties
Build a simple REST application using Spring Boot, embedded Web Server and fat JARs or classic WARs
Implementing REST client applications using RestTemplate
Utilize Spring Boot enhancements to testing
Spring Security
Enable and extend metrics and monitoring capabilities using Spring Boot actuator

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.
