Hibernate Session的update/merge/saveOrUpdate无更新且无异常问题排查

使用org.hibernate.Session的update、merge、saveOrUpdate方法时，数据库未发生更新，且无任何异常抛出。

问题代码（update方法）

@Override
public void update(Domain domain) {
    
    // 创建SessionFactory
    SessionFactory sessionFactory = HibernateUtil.getSessionFactory();

    // 获取Session
    Session session = sessionFactory.openSession();
    
    // 此处返回false
    boolean contains = session.contains((LogItem)domain);
    
    // 尝试过以下所有方法，均无效
    //session.update((LogItem)domain);
    //session.update( ((LogItem)domain).getClass().getName(), (LogItem)domain );
    //session.merge( (LogItem)domain );
    //session.merge( ((LogItem)domain).getClass().getName(), (LogItem)domain );
    //session.saveOrUpdate( (LogItem)domain );
    session.saveOrUpdate( ((LogItem)domain).getClass().getName(), (LogItem)domain );

    // 关闭Session
    session.close();
            
}

正常工作的save和read方法

create方法

public Serializable create(Domain domain) throws NamingException, SQLException {
    
    SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
    Session session = sessionFactory.openSession();
    
    session.save(domain);

    session.close();
    
    return domain;
}

read方法

public Domain read(long id) {
    
    SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
    Session session = sessionFactory.openSession();
    
    LogItem logItem = session.get( LogItem.class, id );

    session.close();
    
    return logItem;
}

Hibernate配置文件（hibernate.cfg.xml）

HibernateUtil工具类

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // 从hibernate.cfg.xml创建SessionFactory
            return new Configuration().configure().buildSessionFactory();
        }
        catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void shutdown() {
        // 关闭缓存和连接池
        getSessionFactory().close();
    }

}

可正常工作的EntityManager实现

@PersistenceContext(unitName = "your_persistence_unit_name")
private EntityManager em;

public void update(Domain domain) {
    
     em.merge(domain);

}

补充：调用链与容器事务配置

DomainHibernateDaoBean（包含所有CRUD方法）

public class DomainHibernateDaoBean {
    
    public Serializable create(Domain domain) throws Exception { ... }

    public Domain read(long id) throws Exception { ... }
    
    public void update(Domain domain) throws Exception { ... }
}

CrudsTransactionSessionBean（容器管理事务）

import javax.ejb.SessionContext;

@Stateless
@TransactionManagement(TransactionManagementType.CONTAINER)
public class CrudsTransactionSessionBean implements CrudSessionLocal {

    private DomainHibernateDaoBean domainHibernateDaoBean = new DomainHibernateDaoBean();       
    private boolean throwException;

    @Resource
    private SessionContext sessionContext;

    public CrudsTransactionSessionBean() {
        super();
    }

    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void update(Domain domain) throws Exception {
        try {
             domainHibernateDaoBean.update(domain);
          
            if (throwException) {
                throw new Exception("Mockup exception");
            }
        } catch (Exception e) {
            sessionContext.setRollbackOnly();
            throw e;
        }
    }

    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public Serializable create(Domain domain) throws Exception {
        try {
            Serializable serializableTemp = domainHibernateDaoBean.create(domain);

            if (throwException) {
                throw new Exception("Mockup exception");
            }
            return serializableTemp;
        } catch (Exception e) {
            sessionContext.setRollbackOnly();
            throw e; 
        }
    }

    @Override
    public Domain read(long id) throws Exception {
        try {
            Domain searchResult = domainHibernateDaoBean.read(id);
            if (throwException) {
                throw new Exception("Mockup exception");
            }
            return searchResult;
        } catch (Exception e) {
            sessionContext.setRollbackOnly();
            throw e;
        }
    }
}

persistence.xml配置

</persistence>

疑问与诉求

原本认为容器事务与HibernateUtil获取的事务是同一事务，但现在对此存疑。设置throwException=true时，create操作会被回滚，这让我疑惑：sessionContext.setRollbackOnly()是否会回滚HibernateUtil的事务？恳请帮忙排查Session更新失效的原因，以及容器事务与Hibernate事务的关联问题。
