BaseService.java
public BaseService() {
    if (SpringUtil.getWebApplicationContext()!=null && SpringUtil.getWebApplicationContext().getBean("dao") != null) {
        this.dao = (IDaoManager) SpringUtil.getWebApplicationContext().getBean("dao");
    }
}

/**
 * 数据库操作 dao
 */
@SuppressWarnings("unchecked")
@Resource
protected IDaoManager dao;

@SuppressWarnings("unchecked")
public void setDao(IDaoManager dao) {
    this.dao = dao;
}

@SuppressWarnings("unchecked")
public IDaoManager getDao() {
    return dao;
}

IDaoManager.java
public class IDaoManager<T, P, PK extends Serializable> extends HibernateDaoSupport implements GeneraDAO<T, P, PK> {

/**
 * <p>
 * 持久化业务逻辑数据对象 ，无返回值
 * </p>
 */
public void saveIObject(final T object) {
    getHibernateTemplate().save(object);
}

/**
 * <p>
 * 持久化业务逻辑数据对象，新增或者更新 ，无返回值
 * </p>
 * 
 * @param object
 *            T 业务逻辑数据对象
 */
public void saveOrUpdateIObject(final T object) {
    getHibernateTemplate().saveOrUpdate(object);
}

我自己的service集成BaseService，我在service里的一个方法内插入两条数据，如果出现异常，把本次对数据库的所有操作回滚，现在问题是回滚失败，代码如下：
public int saveProduct(HmProduct hmProduct) {
int result = ConstanData.SUCCESSCODE;
Session sessions = null;
sessions = this.getDao().getHibernateTemplate().getSessionFactory().openSession();
sessions.beginTransaction();
try {
sessions.save(hmProduct);
HmProductLog hmProductLog = new HmProductLog();
hmProductLog.setProductId(hmProduct.getId());
hmProductLog.setPrice(hmProduct.getPrice());
hmProductLog.setCreateTime(new Date());
sessions.save(hmProductLog);

    } catch (Exception e) {
        // TODO Auto-generated catch block
        sessions.getTransaction().rollback();
        result = ConstanData.FAILURECODE;
        e.printStackTrace();
    }finally{
        sessions.close();
    }
    return result;
}

先看spring版本，低版本需要设置编程式事务，在类中使用curentsession，与当前线程绑定。
