Spring Boot Training Overview
Accelebrate's Spring 6, Spring Boot 3, and Spring REST course teaches attendees how to build, test, and deploy modern Spring applications and RESTful services. This Java Spring training covers essential Spring Core concepts for creating flexible, maintainable, and testable apps. Participants leverage Spring Boot's auto-configuration for effortless setup and dependency management. Students build secure and scalable RESTful APIs with Spring REST and implement data persistence with JPA and Spring Data. By the end of this course, participants are able to confidently implement transaction management in their Spring apps and apply the latest Spring Boot features.
