java - Hibernate 不设置外部约束

Question

我正在使用 Spring 和 Hibernate 开发应用程序。以下是我的模型 bean 类:

员工

@Entity
@Table(name="employee")
public class Employee {
    @Id
    @Column
    @GeneratedValue
    private int empid;
    @Column
    private String firstName;
    @Column
    private String lastName;
    @Column
    private String email;
    @Column
    private String password;
    @Column
    private boolean isAdmin;

    @Column
    private boolean isActive;

    @Column
    private boolean isLocked;

//getter and setter

个人详细信息

public class PersonalDetails {
    @Column
    @Id
    private int empid;
    @Column
    private String personalEmail;
    @Column
    private String mob;
    @Column
    private String permenantAdress;
    @Column
    private String currentAddress;
    @Column
    private String gender;
    @Column
    private String maritialStatus;

    @OneToOne
    @PrimaryKeyJoinColumn
    @ForeignKey(name="empid")
    private Employee employee;

//getter and setter

我的表在服务器启动时自动创建，但 PersonalDetails 表中的外键约束未设置。

我在这里错过了什么吗？

Answer 1

我认为您的 @OneToOne 映射应如下所示:

@MapsId
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "empid", referencedColumnName = "empid")
private Employee employee;

级联属性是可选的，但却是一个很好的做法。
