Multi-Tenancy Demo Project

Demo project for using Multi-Tenancy in Spring Boot

Reference: https://conciso.de/multi-tenancy-in-spring-boot-projekten/

Multi-tenancy describes a system in which an application serves multiple tenants on the server side. This project demonstrates how to build an application using the Multi-Tenancy architecture based on the following technologies:

Java (v.17)
Spring Boot (v.3.1.12)
PostgreSQL (v.15)

In this project each tenant shall use a separate database. In addition, a shared database is used for shared data. This scenario often arises in practice when sensitive data has to be persisted in isolation on the one hand, but is based on a shared data base on the other.

The project represents a minimalistic online store. Products are offered and can be ordered by customers from different countries. Customers and their orders are stored in country-specific databases, so every country describes a tenant.

Example:

curl --location 'localhost:8080/customers' \
     --header 'X-Tenant-Id: spain' \
     --header 'Content-Type: application/json' \
     --data '{
       "customerCode": "testCustomerCode02",
       "firstName": "testFirstName02",
       "lastName": "testLastName02",
       "address": "testAddress02"
      }'
