CRUD Employee Management System A Spring Boot project that provides basic CRUD (Create, Read, Update, Delete) operations for managing employee data. This project demonstrates the use of Spring Boot, JPA for database interactions, and RESTful APIs.

Project Structure The project is structured as follows: crudEmployees-dao ├── src │ ├── main │ │ ├── java │ │ │ └── com.example.crudDemoEmployees │ │ │ ├── DAO │ │ │ │ ├── EmployeeDAO.java │ │ │ │ └── EmployeeDAOJpaImpl.java │ │ │ ├── entity │ │ │ │ └── Employee.java │ │ │ ├── rest │ │ │ │ └── EmployeeRestController.java │ │ │ ├── service │ │ │ │ ├── EmployeeService.java │ │ │ │ └── EmployeeServiceImpl.java │ │ │ └── CrudDemoEmployeesApplication.java │ ├── resources │ └── test ├── target ├── .gitignore ├── HELP.md ├── mvnw ├── mvnw.cmd └── pom.xml

DAO Layer: Contains EmployeeDAO (interface) and EmployeeDAOJpaImpl (implementation using JPA) for data access logic. Entity Layer: Defines the Employee entity class, representing the employee table in the database. REST Controller Layer: EmployeeRestController provides RESTful endpoints to handle HTTP requests for employee data. Service Layer: EmployeeService and EmployeeServiceImpl handle business logic related to employees. Main Application: CrudDemoEmployeesApplication is the entry point for the Spring Boot application.

Features List all employees: Retrieves all employee records. Find employee by ID: Retrieves a single employee record by ID. Save employee: Adds a new employee or updates an existing one. Delete employee: Removes an employee record by ID.
