在我的查询(查找)之后,缓存会话关闭,在新会话中,hibernate在通过随机写入Sql Query更改数据库之后驱逐所有内容,我该如何阻止它发生?我正在研究为很少改变的事情制定政策。

找到了Hibernate问题https://hibernate.onjira.com/browse/HHH-2224
我测试了下面的声音:
在我的随机查询中
<sql-query name="random_write_query" callable="false">
<synchronize table="USER"/>
<synchronize table="USER_ADDRESS"/>
{CALL PACKAGE.FUNCTION(?)}
</sql-query>
每当我调用上面的内容并且它是数据库更改时,它将仅使table = USER或USER_ADDRESS同步的缓存无效
只有同步的随机读取查询或实体才会被驱逐
<sql-query name="random_read_query">
<synchronize table="USER"/>
<synchronize table="USER_ADDRESS"/>
<return-scalar column="USERNAME" type="string"/>
<![CDATA[
SELECT USERNAME FROM USER, USER_ADDRESS...
]]>
</sql-query>
