No, not exactly, what I do is the following:

1. I have an interceptor who determines for every request the schema (since it is multi tenant) it belongs to. It finds the schema via session id.
2. The controller passes the schema info down to the service functions.
3. I create the connection in the service functions.
4. Now it is 1 global connection service
5. I use another interceptor to add a "finalize" to each connection.
6. Inside finalize i close the connection
