Spring Boot – RESTful APIs & JPA

Spring Framework has for long been around as the de facto standard framework for developing Java applications and has been established as a complete base framework that addresses almost all modern business needs via its portfolio projects. Among all Spring solutions, Spring Boot is maybe the most exciting new thing to come. Spring Boot offers a new paradigm for developing web/cloud applications, focusing on minimizing boilerplate code and only leaving the development of the business logic itself for developers. Recognizing the universal dominance of Spring Boot in building modern enterprise web applications, this training course mainly focuses on the common but still demanding problem of designing and implementing efficient and reliable RESTful applications with persistence layer.

The Code.Learn Spring Boot – RESTful APIs & JPA program, designed in exclusive collaboration with Athens Tech College, teaches the participants a lot of best design practices, performance optimization principles, and implementation skills, which can be included in any modern Java enterprise application.
