无法生成java Hibernate会话工厂

Question

我正在使用Hibernate设置一个项目，它看起来像以下伪代码：

@Entity(name = "employees")
@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
public class Employee {

    private long id;
    private String firstName;
    private String lastName;
    private double salary;
    private JobTitle jobTitle;
    private String email;
    

另一类：

@Entity
   @Table(name="teachers")
   @NoArgsConstructor
   @AllArgsConstructor
   public class Teacher extends Employee{

    private int lessons;
    @ManyToOne
    private Classroom room = new Classroom();

另一类：

@Entity
@Table(name = "classroom")
public class Classroom {
    @Id
    private int number;
    private int floor;
    @OneToMany(targetEntity = Teacher.class,mappedBy = "room",fetch = FetchType.EAGER)
    private List<Teacher> teachers = new ArrayList<>();

当我尝试在mySQL中将所有内容构建为模式时，我遇到了以下错误：

Could not determine type for: com.example.demo.entities.Classroom, at table: employees, for columns: [org.hibernate.mapping.Column(room)

Answer 1

尝试类似的方法：

@Entity
class Teacher {
   
   id
   name
   age
   @ManyToMany
   List<Classroom> rooms;

}

@Entity
class Classroom {

    @ManyToMany(mappedBy = "rooms")
    List<Teacher> classRoom;
}
