Java 日期时间为 ISO_DATE_TIME

Question

我想在Java中的DateTimeFormatter ISO_DATE_TIME末尾添加一个Z，而不是硬编码

String sample = "2018-05-11T13:35:11Z";

DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss[.SSS][XXX][X]");

DateTimeFormatter df1 = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss'Z'");

LocalDateTime newLocalDateTime = LocalDateTime.parse(sample, df1);

System.out.println(newLocalDateTime.toString());

输出为:

2018-05-11T13:35:11

我希望输出为 2018-05-11T13:35:11Z

Answer 1

您正在调用 LocalDateTime 的 toString()，您应该调用 format。改变

System.out.println(newLocalDateTime.toString());

至

System.out.println(newLocalDateTime.format(df1));

输出

2018-05-11T13:35:11Z
