升级到 Hibernate 后 AttributeOverrides 不再工作 6

Question

我将以下代码从 Hibernate 5 升级到 6.1.6 并得到以下异常。 似乎 hibernate 在遍历AttributeOverride列表时遇到了某种问题。

主体实体

package com.mypackage

import java.io.Serializable;
import java.time.OffsetDateTime;
import jakarta.persistence.AttributeOverride;
import jakarta.persistence.AttributeOverrides;
import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.Table;


@Entity
@Table
public class MyClass implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "MY_ID", unique = true, nullable = false)
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long myId;
       
    /**
     * The foreign key to the other table.
     */
    @AttributeOverrides(
    {
        @AttributeOverride(name = "column1", column = @Column(name = "column1", nullable = false)),
        @AttributeOverride(name = "column2", column = @Column(name = "column2", nullable = false))
    })
    private OtherTableId otherTableId;

组成的外键

package mypackage;

import java.io.Serializable;
import jakarta.persistence.Column;
import jakarta.persistence.Embeddable;

@Embeddable
public class OtherTableId implements Serializable {

    private static final long serialVersionUID = 1L;

    @Column(name = "column1", nullable = false)
    private int column1;

    @Column(name = "column2", nullable = false)
    private int column2;

    public OtherTableId() {
        super();
    }

    public OtherTableId(int column1, int column2) {
        this.column1 = column1;
        this.column2 = column2;
    }

错误

我在 hibernate 的迁移指南中找不到任何内容。你知道我必须适应什么才能运行 Hibernate 6 吗？

Answer 1

我刚刚在 Hibernate 6.1 和 6.2 CR2 中运行了以下测试，它成功了：

@SessionFactory
@DomainModel(annotatedClasses = {BTest.MyClass.class, BTest.OtherTableId.class})
public class BTest {

    @Test
    void test(SessionFactoryScope scope) {
        scope.inTransaction(s -> {
            MyClass myClass = new MyClass();
            OtherTableId otherTableId = new OtherTableId();
            myClass.otherTableId = otherTableId;
            s.persist( myClass );
        });
        scope.inTransaction(s -> {
            s.createSelectionQuery("from BTest$MyClass").getSingleResult();
        });
    }

    @Entity
    @Table
    public static class MyClass implements Serializable {

        private static final long serialVersionUID = 1L;

        @Id
        @Column(name = "MY_ID", unique = true, nullable = false)
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long myId;

        /**
         * The foreign key to the other table.
         */
        @AttributeOverrides(
                {
                        @AttributeOverride(name = "column1", column = @Column(name = "column1", nullable = false)),
                        @AttributeOverride(name = "column2", column = @Column(name = "column2", nullable = false))
                })
        private OtherTableId otherTableId;
    }

    @Embeddable
    public static class OtherTableId implements Serializable {

        private static final long serialVersionUID = 1L;

        @Column(name = "column1", nullable = false)
        private int column1;

        @Column(name = "column2", nullable = false)
        private int column2;

        public OtherTableId() {
            super();
        }

        public OtherTableId(int column1, int column2) {
            this.column1 = column1;
            this.column2 = column2;
        }
    }
}

因此，无论是什么原因导致此错误，都必须在您没有向我们展示的代码中。
