This project is an example project for Multi Tenancy with Spring Boot:
We start with inserting customers to the database of Tenant TenantOne:
> curl -H "X-TenantID: TenantOne" -H "Content-Type: application/json" -X POST -d "{\"firstName\" : \"Philipp\", \"lastName\" : \"Wagner\"}" http://localhost:8080/customers
{"id":1,"firstName":"Philipp","lastName":"Wagner"}
> curl -H "X-TenantID: TenantOne" -H "Content-Type: application/json" -X POST -d "{\"firstName\" : \"Max\", \"lastName\" : \"Mustermann\"}" http://localhost:8080/customers
{"id":2,"firstName":"Max","lastName":"Mustermann"}
Getting a list of all customers for TenantOne will now return two customers:
> curl -H "X-TenantID: TenantOne" -X GET http://localhost:8080/customers
[{"id":1,"firstName":"Philipp","lastName":"Wagner"},{"id":2,"firstName":"Max","lastName":"Mustermann"}]
While requesting a list of all customers for TenantTwo returns an empty list:
> curl -H "X-TenantID: TenantTwo" -X GET http://localhost:8080/customers
[]
We can now insert a customer into the TenantTwo database:
> curl -H "X-TenantID: TenantTwo" -H "Content-Type: application/json" -X POST -d "{\"firstName\" : \"Hans\", \"lastName\" : \"Wurst\"}" http://localhost:8080/customers
{"id":1,"firstName":"Hans","lastName":"Wurst"}
Querying the TenantOne database still returns the two customers:
> curl -H "X-TenantID: TenantOne" -X GET http://localhost:8080/customers
[{"id":1,"firstName":"Philipp","lastName":"Wagner"},{"id":2,"firstName":"Max","lastName":"Mustermann"}]
Querying the TenantTwo database will now return the inserted customer:
> curl -H "X-TenantID: TenantTwo" -X GET http://localhost:8080/customers
[{"id":1,"firstName":"Hans","lastName":"Wurst"}]
