Question

我有以下实体：

1-地址

@Entity
@Table(name = "Address")
public class Address implements Serializable
{
    private static final long serialVersionUID = 1L;

    @EmbeddedId
    private AddressPK id = new AddressPK();

               @OneToOne(mappedBy = "address")
    private Insurance_Detail insuranceDetail;

}

2- ADDRESSPK

@Embeddable
public class AddressPK implements Serializable
{
    // default serial version id, required for serializable classes.
    private static final long serialVersionUID = 1L;

    @Column(unique = false, nullable = false, length = 45)
    private String customer_EmailAddress;

    @Column(unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int address_Id;

}

3- Insurance_Detail

@Entity
@Table(name = "Insurance_Detail")
public class Insurance_Detail implements Serializable
{
    private static final long serialVersionUID = 1L;

    @EmbeddedId
    private AddressPK id;

    @OneToOne
@JoinColumns({
        @JoinColumn(name = "customer_EmailAddress", referencedColumnName = "customer_EmailAddress", nullable = false, insertable = false, updatable = false),
        @JoinColumn(name = "address_Id", referencedColumnName = "address_Id", nullable = false, insertable = false, updatable = false) })



}

4-持久保存地址对象如下：

Address address= new Address(data1,data2);

address.getId().setCustomer_EmailAddress(
                    currentCustomer.getEmailAddress());

entityManager.persist(address);

5-保留详细信息对象如下：

Insurance_Detail insuranceDetail = new Insurance_Detail(address.getId(), data3,data4);
entityManager.persist(insuranceDetail);

并且没有任何问题正确保存。

问题：在尝试持久 Insurance_Detail 对象时，在首次插入保险时，它已成功保留，但在第二次插入时另一项保险我得到以下例外。

请告知如何修复此异常。

Answer 1

ISSUE在数据库方面，UNIQUE INDEX上有customer_EmailAddress，主键顺序必须等同于连接列

PRIMARY KEY (`Customer_EmailAddress`, `Address_Id`)

ConstraintViolationException使用@EmbeddedId时的重复条目
