Projects
Real Spring Boot projects, dissected layer by layer — architecture, business logic, persistence, error handling, and tests explained in plain language.
Reading reference documentation is one thing; following a real project from first principles to deployment is another. This domain walks through complete, runnable projects so you can connect the dots between concepts like @Embeddable, @RestControllerAdvice, and BigDecimal and the code you would actually write on the job.
