关于cache的刷新

目前有一个功能是这样处理的,流程如下:
xxx.do?method=yyy ---> DispatchAction --> Service ---> Dao
在Dao里做一个UPDATE操作(根据ID,修改表的一个字段) --> 清空cache
log如下：
10:01:40,889 DEBUG [ProxyMethodInvocation] [JdonFramework]enter method reflection
10:01:40,889 DEBUG [ProxyMethodInvocation] [JdonFramework] target:com.sunyark.service.ProductManagerImp service's method:insertMyFile running..

10:01:40,899 DEBUG [JdbcUtil] [JdonFramework] parameter 2 = 192

10:01:41,100 DEBUG [DynamicProxyWeaving] [JdonFramework]call method:insertMyFile finish!
问题：作完修改后，前台查询的时候，修改的字段值没有改变（数据库中值已经改变），为什么已经清空cache后前面的数据没有刷新？
我的分析：是不是因为此动作过程没有经过ModelHandler处理？
请banq老师帮忙分析一下．谢谢．

你修改时必定调用pageIterator的clearCache方法，但是这个pageIterator可能不是你查询是用的那个pageIterator。必须两者保持唯一。

问题:
清空cache的前提下,调用同样一个查询方法getProduct(),为什么产生的日志不一样?
请帮助分析一下导致这种情况发生的原因,我弄了大半天天也没有找出来.
附上日志如下:

一种你是通过代码直接调用，如xxService.getproduct();
二种是你没有写代码，JF通过你的jdonframework.xml中CRUD配置getProduct，使用方法发射机制调用的，类似method.invoke("类名","类方法名");
两条执行路径不一样，所以JF输出不一致。
