set function on Spring Boot entity not persisting

Question

I attached this code to a request mapping

Game g = gRepo.getOne((long)1);
System.out.println(g.getFinished());
g.setFinished(true);
System.out.println(g.getFinished());

My output is:

False
True
False
True

My Game entity setFinished function is:

public void setFinished(Boolean finished) {
    this.finished = finished;
}

I'm looking for the following system print and don't understand why I'm not getting it.

False
True
True
True
