spring3+hibernate4 出现的一个问题
错误是这样的：
当我单独测试dao的时候，会报错：No Session found for current thread
但是把到加入到service时，再测试，就没问题
配置文件如下：

请问这是怎么回事呢，再有就是我这个配置写的规范吗？为什么不能回滚事务呢？ hibernate spring
[解决办法]
都是只读事务。。。
[解决办法]

引用:

试试给你的aop配置，添加roll-back属性，指定异常回滚

是不是这样

<tx:advice id="txAdvice">
<tx:attributes>
<tx:method name="*" rollback-for="Throwable" no-rollback-for="InstrumentNotFoundException"/>
</tx:attributes>
</tx:advice>

楼主先试试
