Hibernate Cache Always Misses

Question

Spring 프레임 워크에서 Hibernate를 사용하고 있으며 CriteriaAPI를 통해 작성된 쿼리를 캐시하려고한다. 쿼리 캐시와 2 차 수준 캐시를 활성화했습니다. 또한 특정 쿼리에서 setCacheable을 true로 설정했습니다. 문제는 최대 절전 모드 세션 통계가 여러 번 실행중인 동일한 쿼리의 모든 데이터베이스를 조회한다는 것입니다. 여기

는 기준 여기

@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(); 
} 

호출자 기능이 클래스

@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); 
}

나는 봄과 최대 절전 모드로 비교적 새로운 해요. 나는이 문제에 관한 적어도 12 개의 기사를 읽고 모든 것을 할 수 있었다. 또한 createQuery 메서드를 사용하여 비슷한 쿼리를 작성 했으므로 결과는 동일합니다. 어떤 도움을 주시면 감사하겠습니다.
