OpenJPA-查询前不刷新

Question

how can i set openjpa to flush before query. When i change some values in database i want to propagate these changes into application.

I tried this settings in persistence.xml:

<property name="openjpa.FlushBeforeQueries" value="true" />
<property name="openjpa.IgnoreChanges" value="false"/> false/true - same behavior to my case
<property name="openjpa.DataCache" value="false"/>
<property name="openjpa.RemoteCommitProvider" value="sjvm"/>
<property name="openjpa.ConnectionRetainMode" value="always"/>
<property name="openjpa.QueryCache" value="false"/>

Any idea? Thanks

在事务内部的对象上调用refresh（）可以达到目的:)
