将从redis中获得的字符串直接转换成对象
从redis中得到的数据：
[{"ct_pt":"xxx","data_time":"xxx","mp_id":"xxx","mp_name":"xxx","pos_p_e_total_e":"xxx","pos_p_e_total_s":"xxx","pos_p_e_total_sub":"xxx","pos_p_e_total_subQuantity":"xxx"}]
List<ElecQuantity> parseArray = JSON.parseArray(elecQuantityStr, ElecQuantity.class);
for (ElecQuantity elecQuantity : parseArray) {
System.out.println(elecQuantity);
}
输出结果为：
[mp_id=xxx, mp_name=xxx, ct_pt=xxx, data_time=xxx, pos_p_e_total_s=xxx, pos_p_e_total_e=xxx, pos_p_e_total_sub=xxx, pos_p_e_total_subQuantity=xxx]
