Question

更新到hibernate后4.3.6保存（实体）不起作用。在更新之前保存看起来像：

public void save(Object entity) {
     getHibernateTemplate().save(entity);
}

它运作得很好。现在它：

public void save(Object entity) {
    getCurrentSession().save(entity);
}

它并没有保存实体。 Hibernate实体和地图是相同的。没有任何改变。问题是当我试图保存实体时，然后我使用ibatis调用存储过程，这需要在DB（Oracle）之前保存实体。数据库中没有数据，因此我的程序崩溃了。

我的问题：hibernate-core 4.3.6有什么问题，这个版本不像hibernate-core 3.5.6（我以前的版本）那样工作。除保存呼叫外，代码无变化。只有图书馆。

当我在调试模式下执行save时：

Answer 1

将@Transactional添加到方法中：

@Transactional
public void save(Object entity) {
    getCurrentSession().save(entity);
}

Hibernate需要一个事务来创建会话。添加此注释后，保存开始起作用。

hibernate 4.3.6 save（entity）oracle
