Java Online Banking System

This Online Banking System is a secure Java web application built with Spring Boot and MySQL that simulates core banking operations. Customers can register, log in, and manage their accounts through a clean dashboard.

Users can view their balance, deposit and withdraw money, transfer funds to other accounts, and see a detailed transaction history. An admin module manages customers, approves new accounts and monitors transactions. Every operation is validated to prevent overdrafts and invalid transfers, and passwords are securely hashed.

The project uses the Spring Boot MVC architecture with Spring Security for authentication, JPA/Hibernate for data persistence, Thymeleaf for views, and a MySQL backend. It demonstrates enterprise Java development, layered architecture, security and transaction management, making it an advanced and impressive final-year project.

Detailed Project Description

Java Online Banking System digitises the day-to-day records and workflows of an organisation so data is stored once, retrieved instantly and reported accurately.

How It Works
1. Role-based login separates admin, staff and end users.
2. Each module (records, bookings, transactions, reports) provides full CRUD operations with validation.
3. Data lives in a relational database with proper relationships between entities.
4. Reports and search views summarise the stored information.

Technology Roles
- Java
- Spring Boot
- Spring Security
- Hibernate
- MySQL

Implementation Steps
1. Define requirements and draw the ER / class diagram and screen flow.
2. Set up the environment (JDK, Spring Boot, MySQL) and create the project skeleton.
3. Design the database schema / data model and seed it with sample data.
4. Implement the core modules with validation and role-based access where needed.
5. Build the user interface and connect it to the backend / data layer.
6. Test each module (unit + manual), fix edge cases and secure inputs (SQL injection, XSS, auth).
7. Prepare documentation, screenshots and a demo build.

Key Features
