How to make custom health check in Spring?

Question

Java

Hello!
There was a need to make a small service on a spring with two endpoints.
The first of them is:
/api/v1/requests?dateStart={dateStart}&dateEnd={dateEnd} - should return data on requests from the database from the opening date to the closing date.
The second one:
/api/v1/status - should report the status of the service itself and the database.
So, actually, the question itself. How can this be implemented without Spring Actuator? It has too comprehensive functionality, and I just need to issue the status of the service and database.
