Hibernate 休眠不保存复合键对象

我遇到了与数据库中的对象持久性相关的问题。 我正在使用这些技术：

• 爪哇
• 马文
• 博士后11.9
• Hibernate 5.3.14.Final-redhat-00001
• JBoss EAP 7.3

我需要对事务进行容器管理，因此这是我的配置：

• 我在JBoss standalone.xml配置中声明了一个数据源：

但现在的问题是

我有以下实体：

• 书

• 书籍作者

我正试图以以下方式保存这些对象：

Session session = HibernateUtil.getSessionFactory().getCurrentSession();

BookDAO book = new BookDAO();
book.setName("The Picture of Dorian Gray")

session.save(book);

AuthorDAO author = new AuthorDAO();
author.setName("Oscar Wilde");

session.save(author);

BookHasAuthorIdDAO id = new BookHasAuthorIdDAO();
id.setIdBook(book.getId());
id.setIdAuthor(author.getId());

BookHasAuthorDAO bookHasAuthor = new BookHasAuthorDAO();
bookHasAuthor.setId(id);
bookHasAuthor.setBook(book);
bookHasAuthor.setAuthor(author);
bookHasAuthor.setPercentage(100);

session.save(bookHasAuthor);

Book成功保存到db中，Author也保存到db中，但BookHasAuthor未保存。不会引发异常，并且hibernate调试日志信息不会显示任何有关插入的信息

但是等等，还不止这些！ 我尝试了以下场景：

• 我用@TransactionManagement（TransactionManagementType.BEAN）注释了我的类，以便自己处理事务，然后我更改了业务实现：

这很有效！但我需要由容器管理事务，因此这不是我的解决方案

• 上次保存后，我尝试保存另一个对象：

这很有效，同时保存了BookHasAuthorDAO和Foo

你有什么解决办法吗？这让我快发疯了。 谢谢你们
