How to find a map from two list of maps using a key present in the map ?

I have 2 list of maps and a key, Both of this list of maps have same key present.

for example

list1 = [{id=123,segmentid=2,journeyid=23,originLocationKey=25},{id=124,segmentid=1,journeyid=24,originLocationKey=26},{id=125,segmentid=3,journeyid=25,originLocationKey=27}]

list2 = [{row=1,segmentid=2,journeyid=23,field=originLocationKey},{row=2,segmentid=1,journeyid=24,field=originLocationKey}]

the key use is segmentid, I want to get the output a map {id=125,segmentid=3,journeyid=25,originLocationKey=27} the segmentid=3 is not present in the list2.

please help
