Spring Boot combines the flexibility of the Spring Framework with productive development. It is the foundation for stable applications in almost every Java project – but often its full potential is not exploited.
In this intensive training course, you will learn the concepts and best practices related to the Spring Framework and Spring Boot. From configuration and AOP to RESTful web services, you will learn how to develop robust and modern enterprise applications.
The focus is on practical, hands-on sessions in which you independently develop an application with Java and Spring. You will gain in-depth knowledge of web technologies, data access, transactions, security, testing, and monitoring, and will then be able to implement complex systems with Spring Boot.
