Hibernate / Envers nie może odczytać odwzorowanego według atrybutu
Nie mogę zaimplementować relacji wiele-do-wielu za pomocą tabeli łączenia (https://stackoverflow.com/a/7603036 & https://en.wikibooks.org/wiki/Java_Persistence/ManyToMany#Mapping_a_Join_Table_with_Additional_Columns). Gdy próbuję odtworzyć, jednostka trwałości nie może zbudować EntityManagerFactory. Wydaje się, że Envers nie potrafi odczytać odwzorowanego według atrybutu, chociaż dla mnie wygląda dobrze. Co ja robię źle? Jaki jest właściwy sposób na wdrożenie relacji wiele-do-wielu z dodatkowymi kolumnami (i Envers)?
Produkt.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>();
...
}
Form.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;
}
}

Kiedy dodam@Audited doProductForm wciąż jest taki sam błąd, poniżej jest najnowszy ślad stosu.
