person-to-interest在我看来就像多对多关系，person\u-interest是Map表。您可以对双向 @ManyToMany 关系式

@Entity
@Table(name = "Person")
public class Person {
    .....

    @ManyToMany
    @JoinTable(
        name = "person_interest ", 
        joinColumns = { @JoinColumn(name = "personId") }, 
        inverseJoinColumns = { @JoinColumn(name = "interestId") }
    )
    private Set<Interest> interests = new HashSet();

    ..... other attributes and getter/setters
}

这是利益与人的逆向关系。

@Entity
@Table(name = "Interest")
public class Interest{
    .....

    @ManyToMany
    private Set<Person> persons = new HashSet();

    ..... other attributes and getter/setters
}
