Introduction to Spring 5, Spring Boot, and Spring REST Training
Spring 5 provides an evolutionary advance of Spring’s powerful capabilities. This course introduces the many Spring Core capabilities, as well as providing guidelines on when and how to use them. It also goes into considerable depth on Spring Boot for dependency management and auto-configuration, as well as Spring REST for creating RESTful resources.
