Vacation Booking Back-End System
A modular Spring Boot back-end system for vacation bookings. Includes RESTful APIs, MySQL integration, data validation, and a well-structured service layer for efficient business logic.
Overview
This project involved building a back-end system for a vacation booking application using Spring Boot, following best practices for web development. The goal was to create a fully functional back-end that connects to a front-end interface and integrates with the MySQL database. The project emphasized modular development using Java and Spring frameworks.
Technologies and Tools Used
- Spring Boot: Framework for building Java-based web applications
- MySQL: Database management system for storing and managing data
- IntelliJ IDEA: Integrated development environment (IDE) for Java
- GitLab: Version control and CI/CD pipelines
Key Features and Tasks
- Package Creation: Organized the project structure into controllers, entities, DAOs, services, and configuration files.
- Entity Relationships: Mapped database tables to entity fields using annotations like
@Entity,@Table, and@Column. Established relationships such as OneToMany and ManyToOne. - Service Layer: Developed a service layer to handle business logic, including checkout processes and order tracking.
- Data Validation: Enforced input validation for required fields and integrated logic for customer data population.
- RESTful Controllers: Built controllers to manage HTTP requests and responses, ensuring seamless data flow between front-end and back-end.
Deployment and Testing
The back-end system was deployed locally for testing using MySQL and integrated with a front-end interface. Additionally, data population was verified with sample customer data to ensure seamless interaction between the front-end and back-end.
