Course Description
All HOTT courses are available face-to-face, remote-live, on-demand or on site at your facility. 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.
This course has been completely revised to utilize Spring Boot's easy configuration and auto-configuration wherever possible. "Classic" Spring configuration (usually more verbose and complicated) is optionally covered in abbreviated form.
The course starts with in-depth coverage of Spring's Core module to reduce coupling and increase the flexibility, ease of maintenance, and testing of your applications. It goes on to cover many of the most important capabilities of Spring, including easing configuration with Spring Boot, integrating JPA persistence layers with Spring and Spring Data, and using Spring's declarative transaction capabilities.
The course includes a solid introduction to Spring REST, and coverage of building RESTful resources. It also covers many of the details of Spring Boot, including how to create Boot-based POMs (maven) for simplified dependency management, customizing Boot behavior, and understanding/managing Boot's auto-configuration.
Comprehensive hands on exercises are integrated throughout the course to reinforce learning and develop real competency. This course will enable students to build working Spring applications with Java and will give students an understanding of the important concepts and technology in a very short time.
Students desiring coverage of Spring MVC rather than Spring Boot may instead be interested in attending the Introduction to Spring 5, Spring MVC and Spring REST course.
