我有一個問題，我不知道如何在 Hibernate 中創建關系數據庫以及如何創建 json i post 方法。我想通過現有的老師和新的學生打交道，我想找到所有有特定老師的學生。我想在學生表中為老師創建類似外鍵的東西。我的代碼：基礎實體@MappedSuperclass@Datapublic class BaseEntity {    @Id    @Column(name = "id")    @GeneratedValue(strategy = GenerationType.IDENTITY)    private Long id;}學生@Entity@Table(name = "student")public class Student extends BaseEntity{    @Column(name = "name")    private String name;    @ManyToOne    private Teacher teacher;...}老師@Entity@Table(name = "teacher")public class Teacher extends BaseEntity{    @Column(name = "name")    private String name;...}教師控制器 @RequestMapping(value = "/add", method = RequestMethod.POST)    public void addTeacher(@RequestBody Teacher teacher) {        teacherService.addTeacher(teacher);    }學生控制器 @RequestMapping(value = "/add", method = RequestMethod.POST)    public void addStudent(@RequestBody Student student) {        studentService.addStudent(student);    }我創建老師時的 JSON 身體：{    "name" : "Test"}學生發布方法應該是這樣的嗎？{        "name": "TestStudent",        "teacher": {            "id": 1,            "description": "Test"        }}
