我有日期字符串“2015-01-12T13:00:00.000+02:00”。查看 JavaDoc,我看到以下内容:
z time-zone name zone-name Pacific Standard Time; PST Z zone-offset offset-Z +0000; -0800; -08:00;
所以我怀疑要解析它,我必须使用大写的“Z”,因为我有 +02:00 中给出的区域格式:
DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000Z");
但是我得到一个解析错误。
如果我使用小写的“z”,它可以工作:
DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000z")
有谁知道发生了什么?
代码:
DateTimeFormatter changetimeParser_Z = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000Z");
DateTimeFormatter changetimeParser_z = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000z");
String time = "2015-01-12T13:00:00.000+02:00";
ZonedDateTime time1 = ZonedDateTime.parse(time, changetimeParser_z);
System.out.println(time1);
ZonedDateTime time2 = ZonedDateTime.parse(time, changetimeParser_Z);
System.out.println(time2);
