Payment Processor Mock-Up App

Overview The Payment Processor Mock-Up App is a demonstration application designed to simulate the handling of payment messages. It supports two types of messages: XML and JSON, and it utilizes modern message queue and serialization techniques.

Features

• Message Acceptance: The application accepts messages in two formats: XML and JSON, via two POST requests.
• Message Handling: Messages are sent through Kafka and consumed by the Message Queue (MQ).
• Serialization and Deserialization: The application performs serialization and deserialization of messages.
• Design Patterns: Utilizes the Strategy Pattern for deserialization of JSON and XML messages.

Usage

POST Requests

• XML Message

Endpoint: /post/xml Content-Type: application/xml Body: XML formatted message

• JSON Message Endpoint: /post/json Content-Type: application/json Body: JSON formatted message

Message Flow

• Sending Messages
• Messages are sent to Kafka.
• Consuming Messages
• Messages are consumed by the MQ.

Serialization/Deserialization

Strategy Pattern: The app uses the Strategy Pattern to handle deserialization for both JSON and XML messages, ensuring a flexible and scalable approach.
