in the interview the day before yesterday, the interviewer asked me how to do one-to-many mapping in hibernate, so I said how to configure it in the hbm file and add collection classes to entity classes as extended objects. In short, I answered the specific use of doing one-to-many mapping. But the interviewer"s expression and reaction don"t seem to be the answer he expected, so what exactly does the interviewer want to ask this question? Ask the boss for advice

entity class:
private Set < bean > beans = new hashSet < bean >; / / to express one-to-many relationship.
