select name,good_index from crawled_goods where channel='jdzgb-beijing' and batch_id='2019070912' and cate2_name='饮料' ORDER BY CONVERT (good_index, signed )

解决方法：（String类型无法直接parse为一个date类型，所以需要先把String字符串，格式化为一个date类型，最后再格式化为你想要的格式） public String formatDate(String inputDate){ try{ DateFormat outputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US); DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX", Locale.US); Date date = inputFormat.parse(inputDate); return outputFormat.format(date); }catch (Exception e){ e.printStackTrace(); return null; } } 文章来源: https://blog.csdn.net/Kevin_Gu6/article/details/90210560
