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();
 
}}));
