操作Hibernate二级缓存

我使用hibernate作为我的ORM解决方案,使用EHCache作为二级(读写)缓存.

我的问题是:是否可以直接访问二级缓存？

我想访问这个:http://www.hibernate.org/hib_docs/v3/api/org/hibernate/cache/ReadWriteCache.html

如何访问Hibernate正在使用的相同ReadWriteCache？

我有一些我正在做的直接/自定义JDBC插入,我想自己将这些对象添加到二级缓存中.

我会在映射到您的实体的EntityPersister上调用"afterInsert",因为Read/Write是一种异步并发策略.在查看Hibernate 3.3源代码后,我将它拼凑在一起.我不是百分之百,这会起作用,但它对我来说很好看.

EntityPersister persister = ((SessionFactoryImpl) session.getSessionFactory()).getEntityPersister("theNameOfYourEntity");

if (persister.hasCache() && 
    !persister.isCacheInvalidationRequired() && 
    session.getCacheMode().isPutEnabled()) {

    CacheKey ck = new CacheKey( 
                    theEntityToBeCached.getId(), 
                    persister.getIdentifierType(), 
                    persister.getRootEntityName(), 
                    session.getEntityMode(), 
                    session.getFactory() 
                );

    persister.getCacheAccessStrategy().afterInsert(ck, theEntityToBeCached, null);
}
