Java Localdatetime解析设置偏移量为5:30，而我希望偏移量为00:00:00

Question

我有如下代码

    String d = "2011-10-24";

    Fun fun = new Fun();
    fun.setTmp(LocalDateTime.parse(d + " 00:00:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));

    fun.save(); // it's saving as 2011-10-24 05:30:00 whereas I want it to be 2011-10-24 00:00:00
    

每当我通过将其设置为实体来保存到我的数据库时，它会添加5:30作为偏移量

您需要使用ZonedDateTime更改时区：

String d = "2011-10-24 00:00:00";
LocalDateTime localDateTime = LocalDateTime.parse(d, DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
ZonedDateTime zonedDateTime = ZonedDateTime.of(localDateTime, ZoneId.of("UTC"));
System.out.println(zonedDateTime.toString());
