OsCache报错error while trying to flush writer

admin

spring2.0+spring3+hibernate3开发
现在想在原有基础上使用 oscache提高性能，使用中发现问题
例如：使用struts2标签
<cache:cache time="60" scope="session">
<s:action  name="ztree.action" executeResult="false"/>
</cache:cache>
其中 这个action功能是从数据库读取数据 报错

但是数据一样能取出来
在一分钟内 刷新该页面 cache包含的部分不再执
百度了很多资料、也尝试了很多方法、其实设置下 参数 flush="false" 为false即可。

<cache:cache time="60" scope="session">
<s:action  name="ztree.action" executeResult="false" flush="false"/>
</cache:cache>

这样后台就不会报错了、具体原因应该是 flush吧不要
