Java - LocalDateTime解析日期字符串值时丢弃秒值“00“,如“2021-07-01 15:33:00“ 转换为“2021-07-01T15:33“

Posted 2021-09-21 Zhang Daopin

    在测试数据的时候，收集到各个时间点上的数据，发现怎么数据有点奇怪，都是中间的时间，没有整秒的数据呢？

    查看后台日志，发现是因为在使用LocalDateTime接收秒值为"00"的数据时，秒值被丢弃掉了 

 wrong date and time parameter format, parameter: 2021-07-01T15:33, format requirement: [yyyy-MM-ddTHH:mm:ss | yyyy-MM-ddTHH:mm:ss.SSS][+HH:mm | -HH:mm | Z], position: character 157, line 1"}

错误的日期和时间参数格式，参数:21-07-01 t15:33，格式要求:[yyyy-MM-ddTHH:mm:ss | yyyy-MM-ddTHH:mm:ss。[+HH:mm | -HH:mm | Z]，位置:字符157，第1行"} 

    但是原来的数据是："2021-07-01 15:33:00" 而不是："2021-07-01T15:33"

    第一种办法可以在字段上增加格式化的指定

@JSONField(format = "yyyy-MM-dd'T'HH:mm:ss")

    第二种办法可以在写库的时候，格式化这个日期

LocalDateTime visitTime = LocalDateTime.new();
String visitTimeFormat = visitTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss"));
