About this course
Spring Boot is the most common way to build Java backends. It also confuses many learners at first: annotations seem to work by magic, beans and dependency injection are new ideas, and errors such as a failed bean wiring or a LazyInitializationException are hard to read.
This course follows the standard Spring Boot curriculum used in industry training: how Spring and Spring Boot work, dependency injection, REST controllers, layered design, validation, error handling, configuration and profiles, Spring Data JPA, transactions, Spring Security with JWT, testing and deployment.
Study on your own with our free Spring Boot, Spring Data JPA and Spring Security lessons, built around one running project. Or learn with an affordable 1:1 mentor who explains each idea with short examples and reviews your work with you. Message us on WhatsApp or email, or fill in the short form, for a free, no-obligation chat. We will suggest a plan that fits your budget and flexible timings, and you can start this week.
