java - Java持久性:无法添加或更新子行:外键约束失败

基本上，我正在实现PDS（个人数据表），因此我拥有诸如客户（员工），Personalinfo，Otherinfo之类的表。

客户端表结构：

idClients, name, institute, username, password, usertype

Personalinfo表结构：

idPersonalInfo, agencyno, bloodtype, status, citizenship, address, idClients

我可以成功添加客户端，但是当我尝试添加/更新个人信息时，我得到了

MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails

在personalinfo类中，我也有这一行：

 @JoinColumn(name = "idClients", referencedColumnName = "idClients", insertable = false, updatable = false)

在客户类中，我还包括：

 @OneToOne(cascade = CascadeType.ALL, mappedBy = "clients")
    private Personalinfo personalinfo;

但是我不知道为什么我遇到约束冲突。

Error Code: 1452
Call: INSERT INTO personalinfo (...) VALUES (...)
    bind => [7parameters bound]
Query: InsertObjectQuery(com.profiling.database.Personalinfo[ idPersonalInfo=null ])

编辑：

if (personal != null) {
          .....
            personal.setClients(client);
            personal.setIdPersonalInfo(client.getIdClients());

            EntityManager em = emanager.getEntityManager();
            em.getTransaction().begin();
            em.persist(personal);
            em.getTransaction().commit();
            JOptionPane.showMessageDialog(rootPane, "Personal Info Updated Successfully");
        } else {
            personal = new Personalinfo();
            ....
            personal.setClients(client);
            client.setPersonalinfo(personal);
            EntityManager em = emanager.getEntityManager();

            em.getTransaction().begin();
            em.persist(personal);
            em.getTransaction().commit();
            JOptionPane.showMessageDialog(rootPane, "New Personal Info Save");
        }

最佳答案

假设您在PersonalInfo类中尝试此操作并检查。

@OneToOne
@JoinColumn(name = "idClients")
