我在下面有以下代码:
public Optional<KoKur> getExchangeRateFromList(final Integer code, List<KotukOdeme> paymentList){
List<LocalDate> paymentDateList = null;
for(KotukOdeme kotukOdeme : paymentList){
paymentDateList.add(kotukOdeme.getOdemeTarihi());
}
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<KoKur> query = cb.createQuery(KoKur.class);
Root<KoKur> koKurRoot = query.from(KoKur.class);
query.where(
cb.and(
cb.equal(koKurRoot.get("dovizTip"), code)
)
);
TypedQuery<KoKur> typedQuery = entityManager.createQuery(query);
List<KoKur> koKurList = typedQuery.getResultList();
return koKurList.isEmpty() ? Optional.empty() : Optional.of(koKurList.get(0));
}
我正在收集paymentDateList中的本地日期列表,我想在查询中将它们添加为IN子句。因此,在“代码”旁边,我也想在AND子句旁边添加IN。当我如下添加时,IDE给我错误;
cb.in(koKurRoot.get("tarih"), paymentDateList)
我该怎么做?
答案 0 :(得分:1)
使用cb.in(koKurRoot.get("tarih")).value(paymentDateList)

这应该有效。如果需要,可向谓词数组添加其他条件
List<Predicate> predicates = new ArrayList<>();
predicates.add(query.get("tarih").in(paymentDateList))
query.where(cb.and(predicates.toArray(new Predicate[predicates.size()])));
return entityManager.createQuery(query).getResultList();
