ehcache hibernate二级缓存,hibernate自动驱逐

Question

在我的查询(查找)得到缓存会话关闭之后,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？我正在考虑为很少改变的事情制定政策.

INFO    Executing [namedSqlQuery=dao.web_login, objs=[user1]]

ecache.xml

 <cache name="query.oneHourPolicy"
           maxElementsInMemory="10000"
           eternal="false"
           timeToLiveSeconds="3600"
           diskPersistent="true"
           overflowToDisk="true"/>

spring hibernate配置

 <prop key="hibernate.cache.use_second_level_cache">true</prop>
                <prop key="hibernate.cache.use_query_cache">true</prop>
                <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</prop>
                <prop key="hibernate.cache.provider_configuration_file_resource_path">ehcache.xml</prop>

发现 Hibernate 问题https://hibernate.onjira.com/browse/HHH-2224

我用下面的测试：

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，它只会使由 table = USER 或 USER_ADDRESS 同步的缓存无效

并且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>
