This project is an example project for Versioning and Auditing Database Tables with Hibernate Envers:
We start by inserting a new Customer into the database. We are using the Username Philipp, which is passed in the X-Username header:
> curl -H "X-Username: Philipp" -H "Content-Type: application/json" -X POST -d "{\"firstName\" : \"Philipp\", \"lastName\" : \"Wagner\"}" http:https://localhost:8080/customers
{"id":26,"firstName":"Philipp","lastName":"Wagner"}
Now we can query the history resource for the customer. At the moment there is only one revision of type add:
> curl -H "X-Username: Philipp" -X GET http:https://localhost:8080/history/customer/26
[{"customer":{"id":26,"firstName":"Philipp","lastName":"Wagner"},"revision":37,"type":"add"}]
Now let's change the last name from Wagner to Mustermann:
> curl -H "X-Username: Philipp" -H "Content-Type: application/json" -X POST -d "{\"id\" : 26, \"firstName\" : \"Philipp\", \"lastName\" : \"Mustermann\"}" http:https://localhost:8080/customers
{"id":26,"firstName":"Philipp","lastName":"Mustermann"}
And in the history we will now see a new revision 38 with the type mod in the history, which shows the modifications:
> curl -H "X-Username: Philipp" -X GET http:https://localhost:8080/history/customer/26
[{"customer":{"id":26,"firstName":"Philipp","lastName":"Wagner"},"revision":37,"type":"add"},{"customer":{"id":26,"firstName":"Philipp","lastName":"Mustermann"},"revision":38,"type":"mod"}]
And if we finally delete the Customer:
> curl -H "X-Username: Philipp" -X DELETE http:https://localhost:8080/customers/26
Then we will see a new revision 42 with the type del in the results:
> curl -H "X-Username: Philipp" -X GET http:https://localhost:8080/history/customer/26
[{"customer":{"id":26,"firstName":"Philipp","lastName":"Wagner"},"revision":37,"type":"add"},{"customer":{"id":26,"firstName":"Philipp","lastName":"Mustermann"},"revision":38,"type":"mod"},{"customer":{"id":26,"firstName":"Philipp","lastName":"Mustermann"},"revision":42,"type":"del"}]
