Spring数据：Hibernate查询缓存不适用于派生查询

我正在尝试为Spring数据中由方法名派生的查询设置Hibernate查询缓存，但是查询缓存从未被使用，或者甚至似乎没有处于活动状态

我正在使用Spring Boot

2.2.1

、Kotlin

1.3.50

、以及带有JCache扩展的咖啡因作为我的底层Hibernate缓存

我的存储库如下所示：

@Repository
interface LibraryRepository : JpaRepository<Library, Long> {
  @QueryHints(QueryHint(name = CACHEABLE, value = "true"))
  override fun findAll(sort: Sort): List<Library>
}

摘自我的配置：

spring:
  jpa.properties:
    javax.persistence.sharedCache.mode: ENABLE_SELECTIVE
    hibernate:
      generate_statistics: true
      session.events.log: true
  hibernate:
    cache:
      use_second_level_cache: true
      use_query_cache: true
      region.factory_class: org.hibernate.cache.jcache.JCacheRegionFactory
    javax.cache.provider: com.github.benmanes.caffeine.jcache.spi.CaffeineCachingProvider

但是，在查询

libraryRepository.findAll（Sort.by（“name”））

时，始终会查询数据库

日志中没有提到有关查询缓存的内容

第一次调用（应该放在缓存中）：

第二次调用（应命中缓存）：
