Description

This comprehensive course provides an in-depth introduction to Spring 6, Spring Boot 3, and Spring REST, aligning with modern development standards such as Java 17+ and Jakarta EE 9. It covers essential Spring Core capabilities, Spring Boot’s auto-configuration and dependency management, and building RESTful services with Spring REST.

Through hands-on exercises, participants will learn to leverage Spring’s powerful features to build scalable, maintainable applications. The course emphasizes Spring Boot for simplified setup and configuration while also covering traditional Spring configuration for comparison.
