java - Spring Data JPA 无法实例化持久性 org.hibernate.persister.entity.JoinedSubclassEntityPersister

Question

我在使用@Inheritance(strategy = InheritanceType.JOINED)时遇到了一个问题，我有四个类涉及到这个问题，Person(父类(super class))，Supplier(子类)，Client(子类)，Transaction(与客户和供应商类)。

现在，我想知道是什么导致了这个小问题:当我删除 Supplier 类时，一切正常，

这里是堆栈跟踪:

涉及的实体:

import javax.persistence.*;
@Entity
@Table(name = "person")
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class Person {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "idperson")
    private Long idPerson;

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

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

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

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

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

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

    // Getters and setters
}

这是 Person 的子类:

import com.abdofx.demo.model.Person;
import com.abdofx.demo.model.tresorerie.Transaction;

import javax.persistence.*;
import java.util.Set;

@Entity
@Table(name = "supplier")
@PrimaryKeyJoinColumn(name = "idperson")
public class Supplier extends Person {

    @OneToMany(mappedBy = "supplier", cascade = CascadeType.MERGE, fetch = FetchType.EAGER)
    private Set<PurchasePiece> purchasePieces;

    @OneToMany(mappedBy = "supplier", cascade = CascadeType.MERGE, fetch = FetchType.EAGER)
    private Set<Transaction> transactions;
}

这是子类客户端

import com.abdofx.demo.model.Person;
import com.abdofx.demo.model.tresorerie.Transaction;

import javax.persistence.*;
import java.util.Set;

@Entity
@Table(name = "client")
@PrimaryKeyJoinColumn(name = "idperson")
public class Client extends Person {

    @OneToMany(mappedBy = "client", cascade = CascadeType.MERGE, fetch = FetchType.EAGER)
    private Set<SellPiece> sellPieces;

   @OneToMany(mappedBy = "sclient", cascade = CascadeType.MERGE, fetch = FetchType.EAGER)
   private Set<Transaction> transactions;
}

事务类:

import com.abdofx.demo.model.purchase.PurchasePiece;
import com.abdofx.demo.model.purchase.Supplier;
import com.abdofx.demo.model.sell.Client;
import com.abdofx.demo.model.sell.SellPiece;
import org.hibernate.annotations.Type;

import javax.persistence.*;
import java.math.BigDecimal;
import java.time.LocalDateTime;
import java.util.HashSet;
import java.util.Set;

@Entity
@Table(name = "transaction")
public class Transaction {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "idtransaction")
    private Long idTransaction;

    @Column(name = "datetransaction ")
    private LocalDateTime dateTransaction;

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

    @Column(name = "value")
    @Type(type = "org.hibernate.type.BigDecimalType")
    private BigDecimal value;

    @Enumerated(EnumType.STRING)
    @Column(name = "direction")
    private DirectionOfTransaction directionOfTransaction;

    // Relationships
    @ManyToOne()
    @JoinColumn(name = "idpaymentmethod")
    private paymentMethode paymentMethode;

    @ManyToOne()
    @JoinColumn(name = "idaccount")
    private Account account;

     @ManyToOne()
     @JoinColumn(name = "sup_idperson")
    private Supplier supplier;

     @ManyToOne()
   @JoinColumn(name = "idperson")
   private Client sclient;


    @ManyToOne()
    @JoinColumn(name = "idtypetransaction")
    private TypeOfTransaction typeOfTransaction;


  @ManyToMany(mappedBy = "transactions", fetch = FetchType.EAGER)
   Set<PurchasePiece> purchasePieces = new HashSet<>();

    @ManyToMany(mappedBy = "selltransactions", fetch = FetchType.EAGER)
      Set<SellPiece> sellPieces = new HashSet<>();

// Getter and setters
}

那么，造成这种问题的原因是什么？

Answer 1

This is a bug with hibernate-core 5.2.14.Final .

在发布几周后有一个紧急版本修复了它，5.2.15.Final .

您有两个修复选项。

如果您只替换有问题的 hibernate-core 没问题，请替换为 5.2.15.Final:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>2.0.5.RELEASE</version>
    <exclusions>
        <exclusion>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>            
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.2.15.Final</version>
</dependency>

否则，请使用较新版本的 spring-jpa 2.0.6 or later .

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>2.0.6.RELEASE</version>
</dependency>
