Mybatis-plus使用@Select注解使用IN查询不出数据的问题

@Select("SELECT p.`name` provinceName ,  p.`province_code` provinceCode , c.`name` cityName, c.`city_code` cityCode, a.`name` areaName, a.area_code areaCode " +
            " FROM region_area a LEFT JOIN region_city c ON a.city_code = c.city_code" +
            " LEFT JOIN region_province p ON c.province_code = p.province_code" +
            " WHERE a.area_code IN(${areaCodes})")
    List<RegionDistrictDetail> selectDistrictDetailData(@Param("areaCodes") String areaCodes);
