Failed to initialize JPA EntityManagerFactory: Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException

Question

I'm working on Spring boot project. Actually, refactoring code.

And getting this mistake as follows: Failed to initialize JPA EntityManagerFactory: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not determine type for: ru.kataproject.p_sm_airlines_1.entity.Document, at table: passenger, for columns: [org.hibernate.mapping.Column(document)]

Any ideas?

Document.java

import lombok.Getter; import lombok.Setter; import ru.kataproject.p_sm_airlines_1.util.enums.DocumentType;

import javax.persistence.*; import java.time.LocalDateTime;

@Entity @Getter @Setter @Table(name="document") public class Document { @Id @GeneratedValue(strategy = GenerationType.IDENTITY, generator = "document_gen") @SequenceGenerator(name = "document_gen", sequenceName = "document_sequence", allocationSize = 1) @Column(name = "id", nullable = false) private Long id;

@Column(name = "document_type", nullable = false)
private DocumentType documentType;

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

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

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

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

@Column(name = "date_of_issue")
private LocalDateTime dateOfIssue;

//todo one to one link to person entity
@Column(name = "person")
private String person = "link to person entity";

}

Passenger.java

import lombok.*;

import javax.persistence.*;
import java.time.LocalDate;

@Getter
@Setter
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Table(name = "passenger", schema = "public")
public class Passenger {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name="id")
    private Long id;

    @NonNull
    @Column(name="document")
    private Document document;  // Заглушка , здесь должна быть сущность Document

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

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

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

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

    @NonNull
    @Column(name="date_of_birth")
    private LocalDate date_of_birth;

}

Answer 1

You should map entities with @ManyToOne or @OneToOne i.e.

@NonNull
@ManyToOne(fetch = LAZY)
@JoinColumn(name="document")
private Document document;
