Web Applications with Spring Boot and Thymeleaf


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.

Web application development is one of the domains in which Spring Boot dominates. Spring enables straightforward and rapid development of RESTful APIs, while also providing a clear architecture and testing solutions. Spring also supports a diverse collection of data storage technologies covering both the Relational and NoSQL databases, while an object-relational mapping framework is also provided in the form of Spring Data JPA.Participants of the Code.Learn Web Applications With Spring Boot and Thymeleaf program, which is designed in exclusive collaboration with Athens Tech College, will be familiarized with all of the above technologies, in addition to learning how to create Java-based views with the Thymeleaf server-side template engine, enabling them to build complete MVC (Model-View-Controller) applications.
