Spring Boot/JPA microservices that use a saga to maintain data consistency

Eventuate Tram Sagas Customers and Orders

This application demonstrates how to maintain data consistency in an Java/JDBC/JPA-based microservice architecture using sagas.

The application consists of two services:

• Order Service - creates orders

• Customer Service - manages customers

Both services are implemented using Spring Boot, JPA and the Eventuate Tram Saga framework

The Order Service uses a saga to enforce the customer’s credit limit when creating orders.
