Mysql 向自引用父级/子级添加一对多关系

使用Spring和Hibernate，我可以在自引用类和另一个类中的父/子类之间实现一对多关系。也就是说，这是自参考类：

DB:

型号：

  @Entity
  @Table(name="employee")
  public class Employee {

  @Id
  @Column(name="employee_id")
  @GeneratedValue
  private Long employeeId;

  @Column(name="name")
  private String name;

  @ManyToOne(cascade={CascadeType.ALL})
  @JoinColumn(name="manager_id")
  private Employee manager;

  @OneToMany(mappedBy="manager")
  private Set<Employee> employee = new HashSet<Employee>();

---

这是我试图实现的概述，但我想知道这是否可行，如果可行，我将如何在DB关系中设置它，并通过hibernate将关系保存到DB。

感谢您的回复。这就是我在Java类中实现的关系，但我不确定的部分是将其转换为数据库，特别是通过Manager id（实际上是外键）实现的Courses和Manager之间的关系。创建表

courses

（

courseid

BIGINT（10）非空自动增量，

manager\u id

BIGINT（20）空默认空，

讲师id

BIGINT（20）空默认空，

@OneToMany(mappedBy="manager") 
private List<Course> managedCourses = new ArrayList<Course>();

@OneToMany(mappedBy="lecturer")
private List<Course> lectuedCourses = new ArrayList<Course>();

  @OneToMany(mappedBy="manager")
  private List<Course> course = new ArrayList<Course>();

  @OneToMany(mappedBy="lecturer")
  private List<Course> courses = new ArrayList<Course>();

  @Entity
  @Table(name = "courses")
  @Component
  public class Course implements Serializable

  @ManyToOne
  @JoinColumn(name="employee_id", insertable=false, updatable=false)
  private Employee employee;

  @ManyToOne
  @JoinColumn(name="manager_id", insertable=false, updatable=false)
  private Employee manager;

@OneToMany(mappedBy="manager") 
private List<Course> managedCourses = new ArrayList<Course>();

@OneToMany(mappedBy="lecturer")
private List<Course> lectuedCourses = new ArrayList<Course>();

@Entity
@Table(name = "courses")
@Component
public class Course implements Serializable

@ManyToOne
@JoinColumn(name="lecturer_id", insertable=false, updatable=false)
private Employee lecturer;

@ManyToOne
@JoinColumn(name="manager_id", insertable=false, updatable=false)
private Employee manager;
