Question

我在春天3使用hibernate 4，我在xml中配置它：

我用dao。当我进行交易（保存，获取，更新）时，它在第一次工作，第二次我收到交易关闭的错误。我在我的dao中为每个函数使用@Transactional注释，所以我无法找出没有事务的原因。

任何人都可以告诉我我做错了什么吗？

感谢

您配置的不寻常之处是：

<prop key="hibernate.connection.aggressive_release">false</prop>                    
<prop key="hibernate.connection.release_mode">after_transaction</prop>  
<prop key="hibernate.connection.autocommit">true</prop>

我会尝试没有那些线。

从参考文档：不建议使用自动提交模式 hibernate.connection.autocommit
为JDBC池连接启用自动提交（不建议这样做）。例如是的|假 hibernate.connection.release_mode指定Hibernate何时应该释放JDBC连接。默认情况下，将保持JDBC连接，直到会话显式关闭或断开连接。对于应用程序服务器JTA数据源，使用after_statement在每次JDBC调用后积极地释放连接。对于非JTA连接，通常使用after_transaction在每个事务结束时释放连接是有意义的。 auto将为JTA和CMT事务策略选择after_statement，为JDBC事务选择after_transaction
