hibernate 4.3.6保存(实体) oracle

Question

更新到hibernate后，4.3.6保存(实体)无法工作。在更新保存之前，如下所示：

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

而且效果很好。现在它是：

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

也救不了实体。Hibernate实体和映射是相同的。什么都没改变。问题是，当我试图保存实体时，我调用的存储过程使用的是ibatis，它需要在DB (Oracle)中保存实体。DB中没有数据，所以我的过程崩溃了。

我的问题是: hibernate-core 4.3.6这个保存不像hibernate-core 3.5.6 (我以前的版本)有什么问题。除保存调用外，代码中没有任何更改。只有图书馆。

当我在调试模式上执行保存时：

Answer 1

在该方法中添加@Transactional：

@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，保存开始工作。
