我需要使用OneToOne注释通过jpa将2个表连接到一个对象中

Question

我想通过JPA使用具有共享主键的OneToOne注释将表连接到一个对象中，但是我不确定该怎么做。我遇到错误：

  

org.springframework.beans.factory.BeanCreationException：错误   在类路径中创建名称为“ entityManagerFactory”的bean   资源   [org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaConfiguration.class]：   调用init方法失败；嵌套异常为   org.hibernate.AnnotationException：未知的映射于：   com.maciejg.School02.model.StudentsTeachersEntity.loginAndPassword，   引用的属性未知：   com.maciejg.School02.model.LoginAndPassword.usersinfo

@Entity
@Table(name="usersinfo")
public class StudentsTeachersEntity {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;

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

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

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

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

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

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

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

    @OneToOne(mappedBy = "usersinfo", cascade = 
        CascadeType.ALL)
    private LoginAndPassword loginAndPassword;

//getters and setters


@Entity
@Table(name="userandpassword")

public class LoginAndPassword {

    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private Long username_id;

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

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

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

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

    @OneToOne
    @JoinColumn
    @MapsId
    private StudentsTeachersEntity studentsTeachersEntity;

//getters and setters
