如何按日期对查询结果进行排序(Jpa,Java Collections)

import javax.persistence.criteria.CriteriaBuilder;
import javax.persistence.criteria.CriteriaQuery;
import javax.persistence.criteria.Root;

// ...

EntityManager entityManager = ...;
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<YourEntity> criteriaQuery = criteriaBuilder.createQuery(YourEntity.class);
Root<YourEntity> root = criteriaQuery.from(YourEntity.class);

criteriaQuery.select(root).orderBy(criteriaBuilder.asc(root.get("dateField")));

TypedQuery<YourEntity> query = entityManager.createQuery(criteriaQuery);
List<YourEntity> resultList = query.getResultList();

String jpql = "SELECT e FROM YourEntity e ORDER BY e.dateField ASC";
TypedQuery<YourEntity> query = entityManager.createQuery(jpql, YourEntity.class);
List<YourEntity> resultList = query.getResultList();

import java.util.Collections;
import java.util.Comparator;
import java.util.List;

// ...

List<YourEntity> resultList = ...;

Collections.sort(resultList, new Comparator<YourEntity>() {
    @Override
    public int compare(YourEntity o1, YourEntity o2) {
        return o1.getDateField().compareTo(o2.getDateField());
    }
});
