Introduction to Spring 6, Spring Boot 3, and Spring REST Training
This Spring course teaches you how to leverage Spring Core capabilities and provides guidelines on when and how to use them. It also dives deep into using Spring Boot for dependency management, auto-configuration, and Spring REST for creating RESTful resources. By the end of the training, students confidently build modern Spring applications.
