Java Hibernate缓存始终未命中

我正在使用Hibernate和Spring框架，并尝试缓存通过CriteriaAPI编写的查询。我已经启用了查询缓存和二级缓存。在该特定查询中，我还将setCacheable设置为true。问题是hibernate会话统计数据显示，对于我多次运行的同一个查询，它会访问数据库的所有内容

下面是带有条件查询的函数

@Override
public Collection<Article> findLatestArticle(int count) {
    // TODO Auto-generated method stub
    Criteria criteria = this.getSession()
    .createCriteria(Article.class)
    .setCacheable(true)
    .setCacheRegion(CACHE_REGION)
    .add(Restrictions.eq("isVisible", 1))
    //.createCriteria("Count")
    //.add(Restrictions.eq("Count", count))
    .setFirstResult(0)
    .setMaxResults(count);

    return criteria.list();
}

我对春天和冬眠相当陌生。关于这个问题，我已经读了至少十几篇文章，并且尽了我所能。另外，我使用createQuery方法编写了一个类似的查询，结果是相同的。任何帮助都将不胜感激。

请尝试为此启用注释 @可缓存

@cache with cache strategies

是用@cache annotation？？？@chrislhardin标记的文章对象：是的，我这样添加了它们

@Entity@Cache（用法=cacheconcurrencysttrategy.READ_WRITE）@Table（name=“ARTICLE”）公共类文章实现了可序列化的{..

@Test
public void t1(){
    List<Article> articleList = (List<Article>) articleDao.findLatestArticle(1);

    //Article a = articleDao.findById(articlePk);

    for(int i=0; i<19; i++)
        articleDao.findLatestArticle(1);

    Statistics stats = sessionFactory.getCurrentSession().getSessionFactory().getStatistics();

    //System.out.println("2nd Lvl Stats: " + stats.getSecondLevelCacheStatistics(CACHE_REGION));
    stats.logSummary();

    System.out.println("Empty: " + articleList.isEmpty());

    assertTrue(!articleList.isEmpty());
    //assertNotNull(a);
}
