-------------------------------------------------------------------------------- /readme.md: -------------------------------------------------------------------------------- 1 | # Employee Management API 2 | 3 | This is a rest API application built using **Spring Boot**, **Spring Data JPA**, and **MySQL**. It allows managing employee records, including creating, reading, updating, and deleting employee data. The application uses a MySQL database to store employee information. 4 | 5 | --- 6 | 7 | ### 1. Technologies Used 8 | 9 | --- 10 | 11 | - Java 12 | - Spring Boot 13 | - Spring Data JPA 14 | - Spring Web 15 | - MySQL 16 | - Lombok 17 | 18 | --- 19 | 20 | ### 2. Getting Started 21 | 22 | --- 23 | 24 | To run this application locally, you'll need a Java Development Environment (JDK), MySQL server, and an IDE (e.g., VS-Code, Eclipse). 25 | 26 | 1. Clone the repository or download the source code. 27 | 2. Import the project into your preferred Java IDE. 28 | 3. Set up a MySQL database and update the database connection details in `application.properties`. 29 | 4. Build and run the application. 30 | 5. The application will be accessible at `http://localhost:8080/api/v1/employees`. 31 | 32 | --- 33 | 34 | ### 3.
