JpaSpecificationExecutor和Java8 Stream

Question

然后JpaSpecificationExecutor接口具有

library(dplyr)
homeWinOdds <- matchData %>% 
  group_by(Season, HomeTeam) %>% 
  summarize(W    = sum(FTR == "H"), 
            AHWO = mean(HWO)) %>%
  ungroup()

存在使用规范实现Stream的某种方式吗？

List<T> findAll(Specification<T> spec)

Page<T> findAll(Specification<T> spec, Pageable pageable);
