JPA中实现查询list_iamlzyoco的博客_jpa list

//创建搜索条件
Specification specification = new Specification() {
    @Override
    public Specification and(Specification other) {
        return null;
    }
    @Override
    public Specification or(Specification other) {
        return null;
    }
    @Override
    public Predicate toPredicate(Root root, CriteriaQuery criteriaQuery, CriteriaBuilder criteriaBuilder) {
        //增加筛选条件
        Predicate predicate = criteriaBuilder.conjunction();
        predicate.getExpressions().add(criteriaBuilder.equal(root.get("plateNo"), plateNo));
        predicate.getExpressions().add(criteriaBuilder.between(root.get("sendTime"), startTime, endTime));
        Order sendtime = criteriaBuilder.desc(root.get("sendTime"));
        return criteriaQuery.orderBy(sendtime).where(predicate).getRestriction();
    }
};
//
List resultList = gpsinfoService.getDao().getRepo().findAll(specification);//创建搜索条件
