SpringBoot中JPA，返回List排序

这里简单示例，利用query，根据“createtime”字段，进行 desc 排序，最近日期的数据在最前面。

public List<StatusEvent> findAll(Specification<User> spec);

    map.addAttribute("resultList",statusEventRes.findAll(new Specification<User>(){

    @Override

    public Predicate toPredicate(Root<User> root, CriteriaQuery<?> query,

    CriteriaBuilder cb) {

    List<Predicate> list = new ArrayList<Predicate>();

    Predicate p1 = cb.or(cb.equal(root.get("discalled").as(String.class), ani2),cb.equal(root.get("discaller").as(String.class), ani2));

    list.add(p1);

    Predicate[] p = new Predicate[list.size()];

    query.where(cb.and(list.toArray(p)));

    query.orderBy(cb.desc(root.get("createtime")));

    return query.getRestriction();

}}));
