Most SF that I recall reading that uses spin gravity handles this problem
by having a counter-rotating 'core', so that in the outside frame of
reference there is a non-rotating portion of both station and ship, and you
perform end-on (ship-end-to-station-end) docking with only the non-rotating
portions coming into mutual contact. Passengers and cargo are also
transferred through this non-rotating portion, in zero-g. Some complex
mechanism to enable transfer between the rotating and non-rotating portions
(a "gravity lock", analogous to an airlock) is necessary.

An alternative that I have also seen is that ship and station rotate at the
same angular speed, but in opposite directions. When the ship approaches
the station docking port, they are rotationally motionless _relative to
each other_. In this model, passenger and cargo transfer is still in zero-g
(or micro-g), but no "gravity lock" is required.

(An example of the latter appears in the novel _Triple Detente_, by Piers
Anthony - human and kazo ships rotate in opposite directions, and transfers
between them are via nose-to-nose docking. A good read, even if the author
has exhibited some distasteful and questionable proclivities in some of his
most popular works.)
