Hibernate / Envers无法读取映射的属性 [英] Hibernate/Envers unable to read the mapped by attribute

查看：194
本文介绍了Hibernate / Envers无法读取映射的属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我无法使用连接表实现多对多关系（ https://stackoverflow.com/a/7603036& https://en.wikibooks.org/wiki/Java_Persistence/ManyToMany#Mapping_a_Join_Table_with_Additional_Columns ）。当我尝试重现它时，持久单元无法构建EntityManagerFactory。 Envers似乎无法读取映射的属性，虽然它看起来不错。我究竟做错了什么？使用额外列（和Envers）实现多对多关系的正确方法是什么？



Product.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表单; 
 
 public ProductForm（Product product，Form form）{
 this.product = product; 
 this.form = form; 
 
 $ b @Embeddable 
 @SuppressWarnings（serial）
 public class ProductFormId实现Serializable {
 @Column（name =product_id）
公共长产品; 
 
 @Column（name =form_id）
 public Long form;

I am unable to implement many-to-many relation using join table (https://stackoverflow.com/a/7603036 & https://en.wikibooks.org/wiki/Java_Persistence/ManyToMany#Mapping_a_Join_Table_with_Additional_Columns). When I try to reproduce it persistence unit is unable to build EntityManagerFactory. It seems that Envers fails to read the mapped by attribute, although it looks good to me. What am I doing wrong? What is the right way™ to implement many-to-many relation with extra columns (and Envers)?

 解决方案 
If you problem is caused by Composite keys, then update your hibernate version to 5.2.2 if possible. Because this bug was fixed in this version.



See: https://hibernate.atlassian.net/browse/HHH-7625
