我目前正试图将spring与spring集成。我使用dao设计模式和mysql作为数据库。我试图在数据库中添加contacte实体,但没有添加,也没有显示错误。顺便说一下,我可以获取联系人列表并通过ID获取它,但我无法更新或插入。休眠和弹簧综合问题

你得到什么错误讯息? –

我没有错误信息 –

你已经上传了代码到github,以便我们可以在本地尝试它? –

你并不需要在所有的DAO实现添加@Transactional注释,如果你已经添加@Transactional注释上GenericDaoImp,和其他东西放在@Transactional(readOnly = false)注释on方法你只能获取数据。这是唯一的建议,仅在

<property name="defaultAutoCommit" value="true" />

更换<property name="defaultAutoCommit" value="false" />
我已经试过了,其工作对我来说,你的问题将得到解决。

我做到了,但它不工作 –

是的,它工作后,我用 =“true”/>。 谢谢:) –

问题可能是您需要启用注释支持以及事务。尝试添加以下到您的Spring XML:

<context:annotation-config/> 
<tx:annotation-driven />
