Banking Application with Spring Boot

This repository contains a simple banking application implemented using Spring Boot, Spring Data JPA (Hibernate), and MySQL. The application demonstrates basic banking functionalities such as creating a bank account, fetching account details, and performing deposits and withdrawals via REST APIs.

Features

• Create a Bank Account: Add a new bank account with the account holder’s name and initial balance.
• Fetch Account Details: Retrieve details of an existing bank account by its unique ID.
• Deposit Money: Deposit a specified amount into an account.
• Withdraw Money: Withdraw a specified amount from an account, with checks for sufficient funds.

Technologies Used

• Spring Boot: Framework for building REST APIs.
• Spring Data JPA (Hibernate): Object-Relational Mapping (ORM) for database interactions.
• MySQL: Relational database for storing account data.
• Lombok: Reduces boilerplate code with annotations.
