Spring Boot JNDI resource-ref

Question

I need to declare a resource-ref in a Spring Boot application that will be deployed as war file. This is needed in order to access the database. In traditional webapps, this is added to the web.xml. How can I achieve this in a Spring Boot way?

Thanks, Benjamin

We got that resolved a while back, so I thought, I'd post this here.
