hibernate - Hibernate/Envers がマッピングされた属性を読み取れない

Question

結合テーブルを使用して多対多の関係を実装できません ( https://stackoverflow.com/a/7603036 & https://en.wikibooks.org/wiki/Java_Persistence/ManyToMany#Mapping_a_Join_Table_with_Additional_Columns )。再現しようとすると、永続ユニットは EntityManagerFactory を構築できません。私には良さそうに見えますが、Envers はマップされた by 属性の読み取りに失敗しているようです。私は何を間違っていますか？追加の列 (および Envers) を使用して多対多の関係を実装する正しい方法は何ですか?

製品.java

@Entity
@Audited
public class Product extends UserModel {
...
    @OneToMany(mappedBy = "product", orphanRemoval = true, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    public List<ProductForm> forms = new ArrayList<ProductForm>();
...
}

フォーム.java

@Entity
@Audited
public class Form extends UserModel {
...
    @OneToMany(mappedBy = "form", fetch = FetchType.LAZY)
    public List<ProductForm> products = new ArrayList<ProductForm>();
...
}

ProductForm.java

@Entity
@Table(name = "Product_Form")
@IdClass(ProductForm.ProductFormId.class)
public class ProductForm {
    @Id
    @JoinColumn(name = "product_id")
    @ManyToOne
    public Product product;

    @Id
    @JoinColumn(name = "form_id")
    @ManyToOne
    public Form form;

    public ProductForm(Product product, Form form) {
        this.product = product;
        this.form = form;
    }

    @Embeddable
    @SuppressWarnings("serial")
    public class ProductFormId implements Serializable {
        @Column(name = "product_id")
        public Long product;

        @Column(name = "form_id")
        public Long form;
    }
}

問題の原因が複合キーである場合は、可能であれば休止状態のバージョンを 5.2.2 に更新してください。このバグはこのバージョンで修正されたためです。

あなたが目指しているのは、私が見た「関連エンティティ」と呼ばれるものです。私はそれらのいくつかを持っていますが、それらの周りには多くのエッジケースがある傾向があるため、一般的に複合 ID を使用しないことをお勧めします.

代わりに、関連付けエンティティに独自の ID を指定し、外部キーのペアに一意のインデックスを配置してから、2 つの関連付けられたエンティティの関連付けを追加します (それらの ID は省略します)。以下は、簡略化された例です。

@Entity
class A {
   @Id
   private Integer aId;

   @OneToMany(mappedBy="a")
   private AtoB aToB;
}

@Entity
class B {
   @Id
   private Integer bId;

   @ManyToOne
   @JoinColumn(name="b")
   private AtoB aToB;
}

@Entity
class AtoB {

  @Id
  private Integer aToBId;

  @ManyToOne
  @JoinColumn(name="aId")
  private A a;

  @OneToMany(mappedBy="aToB")
  private B b;
}

これは理にかなっていますか？

Hibernate に関する限り、1 対多の関連付けを持つ 3 つのエンティティがあります。

したがって、「結合」エンティティを監査するようにすると、トリックが実行@AuditedされProductFormます。
