我想使用spring的transactionManager。我的春天配置是在这里：@transactional不工作春天4冬眠4

</beans>

这是我Manager类中的一种：

import org.springframework.transaction.annotation.Transactional; 

public class UserMgr extends BaseUserMgr { 

    @Transactional (rollbackFor = Exception.class) 
    public void checkTransaction(){ 
     Feature feature = new Feature(); 
     feature.setExtuid(UUID.randomUUID().toString()); 
     feature.setName("boogh"); 
     feature.setDescription("salam"); 
     FeatureDAO.getInstance().save(feature); 
    } 
}

当我运行UserMgr.checkTransaction（）数据不保存。任何人都可以向我解释什么是错的？

__UPDATE___

这是我FeatureDao保存方法：

 public java.lang.Long save(com.example.model.user.Feature feature) 
     throws org.hibernate.HibernateException { 
     return (java.lang.Long) super.save(feature); 
    }

，这是超保存方法：

protected Serializable save(final Object obj) { 
    return save(obj, getSession()); 
}

和getSession（）方法得到春天SessionFactory的会议。

这是我FeatureDao getInstance（）方法：

public static com.model.user.dao.FeatureDAO getInstance() { 
    return com.example.core.spring.ApplicationContextUtil.getApplicationContext().getBean(com.example.model.user.dao.FeatureDAO.class); 
}

我觉得你FeatureDAO不是一个Spring bean =>它不是由Spring包裹AOP =>它独立管理会话和事务，而无需处理Spring事务。 **请添加FeatureDAO源代码，这个问题要回答**。 – 2014-09-02 12:38:44

在你的情况春天会默认使用JDK代理。这将要求您在界面级别拥有@Transactional。

要启用类级别使用@Transactional你可以春天配置为使用CGLIB代理如下

<tx:annotation-driven transaction-manager="transactionManager" 
proxy-target-class="true" />
