我的代码有一些关于HibernateMap的问题。它告诉我**原因：org.hibernate.MappingException:无法确定的类型：**此处是CompanyEntity类

@Entity
@Table(name = "company", schema = "sit2job")
public class CompanyEntity {

    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    private int companyId;
    private String address;
    private String contactPersonName;
    private String description;
    private String detail;
    private String email;
    private String faxNo;
    private String name;
    private String phoneNo;
    private String website;

    @OneToOne
    @JoinColumn(name="user_id")
    private UserEntity userId;

    public UserEntity getUserId() {
        return userId;
    }

    public void setUserId(UserEntity userId) {
        this.userId = userId;
    }

    @Id
    @Column(name = "company_id", nullable = false)
    public int getCompanyId() {
        return companyId;
    }

    public void setCompanyId(int companyId) {
        this.companyId = companyId;
    }

    @Basic
    @Column(name = "address", nullable = true, length = 500)
    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Basic
    @Column(name = "contact_person_name", nullable = true, length = 500)
    public String getContactPersonName() {
        return contactPersonName;
    }

    public void setContactPersonName(String contactPersonName) {
        this.contactPersonName = contactPersonName;
    }

    @Basic
    @Column(name = "description", nullable = true, length = 500)
    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    @Basic
    @Column(name = "detail", nullable = true, length = 500)
    public String getDetail() {
        return detail;
    }

    public void setDetail(String detail) {
        this.detail = detail;
    }

    @Basic
    @Column(name = "email", nullable = false, length = 50)
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Basic
    @Column(name = "fax_no", nullable = true, length = 25)
    public String getFaxNo() {
        return faxNo;
    }

    public void setFaxNo(String faxNo) {
        this.faxNo = faxNo;
    }

    @Basic
    @Column(name = "name", nullable = false, length = 100)
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Basic
    @Column(name = "phone_no", nullable = false, length = 25)
    public String getPhoneNo() {
        return phoneNo;
    }

    public void setPhoneNo(String phoneNo) {
        this.phoneNo = phoneNo;
    }

    @Basic
    @Column(name = "website", nullable = true, length = 100)
    public String getWebsite() {
        return website;
    }

    public void setWebsite(String website) {
        this.website = website;
    }

这是UserEntity类

@Entity
@Table(name = "user", schema = "sit2job")
public class UserEntity {
    private int userId;
    private String username;
    private String password;

    @ManyToOne
    @JoinColumn(name="role_id")
    private RoleEntity roleId;

    @OneToOne(mappedBy = "userId", cascade = CascadeType.ALL)
    @PrimaryKeyJoinColumn
    private CompanyEntity companyId;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "user_id", nullable = false)
    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }

    @Basic
    @Column(name = "username", nullable = false, length = 50)
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Basic
    @Column(name = "password", nullable = false, length = 200)
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public RoleEntity getRoleId() {
        return roleId;
    }

    public void setRoleId(RoleEntity roleId) {
        this.roleId = roleId;
    }

    public CompanyEntity getCompanyId() {
        return companyId;
    }

    public void setCompanyId(CompanyEntity companyId) {
        this.companyId = companyId;
    }

这两个类位于不同的包中它有错误

我想知道这些问题的原因是什么。我认为问题的原因是@OneToOne，因为@OneToMany或@ManyToOne没有任何问题。

spring-data-jpa

看起来您要将companyIdMap到userId，您还需要提供列的名称，如下所示：@JoinColumn(name="company_id")
所以你可能想要这样的东西：

@OneToOne(mappedBy = "companyId", cascade = CascadeType.ALL)
@PrimaryKeyJoinColumn
@JoinColumn(name="company_id")
private CompanyEntity companyId;
