双向亲子关系

Question

在这种情况下如何设计JPA双向重定向？

 Class Person{
       List<Person> relatedPersons;

       Person parentPerson;

    }

我尝试下一步，但接收递归。

  Class Person{
           @OneToMany(mappedBy = "parentPerson")
           List<Person> relatedPersons;

           @ManyToOne
           @JoinTable(joinColumns = {@JoinColumn(name = "related_person_id", referencedColumnName = "id") 
           Person parentPerson;

        }

Answer 1

试试这个：

Class Person{
       @OneToMany (mappedBy = "parentPerson")
       List<Person> relatedPersons;

       @ManyToOne
       @JoinColumn(name="PARENT_PERSON_ID")
       Person parentPerson;
    }
