Lab Overview

Welcome to the Employee Management System CRUD Microservice Interactive Lab. In this lab, you can browse a fully functional Spring Boot microservice structured just like a real-world enterprise project in an IDE.

Use the file explorer sidebar to inspect the layers of this microservice:

  • Entity Layer: Check how the JPA annotations configure the database mapping.
  • Repository Layer: See how Spring Data JPA reduces boilerplate database queries.
  • Service Layer: Inspect business logic, transactional settings, and mapping implementation.
  • Controller Layer: Analyze HTTP endpoint mappings, payload validation, and responses.
  • Configuration and Build: Review the pom.xml dependencies and Eureka configurations in application.yml.
