About This Architecture

Hotel booking REST API architecture using Spring Boot with layered separation of concerns across controllers, services, and data persistence. Client requests flow through the Spring Boot REST API to controllers, which delegate to booking and payment services that interact with PostgreSQL and a mock payment gateway. This three-tier pattern isolates business logic from HTTP handling and database operations, enabling independent testing and maintenance of each layer. Fork this diagram on Diagrams.so to customize service boundaries, add authentication middleware, or integrate a real payment processor. The mock gateway approach is ideal for development and staging environments before connecting production payment systems.

How do you structure a Spring Boot REST API for a hotel booking system with payment processing?

Use a layered architecture with client requests flowing through Spring Boot REST API controllers to booking and payment services, which persist data in PostgreSQL and communicate with a payment gateway. This separation enables independent testing, scalability, and easy swapping of payment providers.
