최대 절전 모드 캐싱 성능이 향상되지 않습니다

Question

내 응용 프로그램의 context.xml :

이

import javax.persistence.Cacheable; 
import org.hibernate.annotations.Cache; 

@Cacheable 
@Cache(usage = org.hibernate.annotations.CacheConcurrencyStrategy.READ_ONLY)

하지만 눈에 띄는 개선점을 발견 할 수 없었습니다. 내가 놓친 게 있니?

내 제약 조건은 다음과 같습니다 내 코드는 JPA 준수에 필요로

1. 내 코드에서 직접 (org.hibernate.annotations.Cache)처럼 최대 절전 모드 사용할 수 없습니다.
2. 내 항목에 주석이 달립니다. 그래서, 콩은 hbm.xml

Answer 1

사용

net.sf.ehcache.hibernate.EhCacheRegionFactory이 최대 절전 모드 공장

대신

org.hibernate.cache를 통해 캐시 가능을 구성 할 수 없습니다 .ehcache.SingletonEhCacheRegionFactory

나는 내 프로젝트에서 ehcache를 사용하고 있었으며 확실히 no.를 줄였다. 해고 된 쿼리 중

문제가 있으면 알려주세요.
