[英]How to remove decimal point in an Java Instant data type
I get this error whenever I try to remove the decimal point of the Instant datatype in java.每当我尝试在 java 中删除 Instant 数据类型的小数点时,都会收到此错误。
! java.util.IllegalFormatConversionException: M != java.time.Instant
Here is the line of code I am trying to use for the conversion.这是我尝试用于转换的代码行。 I am using String.format
我正在使用 String.format
subCategory.setSla(Instant.parse(String.format("%tM", Instant.ofEpochSecond(dto.getSla().atZone(ZoneOffset.UTC).getMinute()))));
Without the string format, I get something like 24.00000
没有字符串格式,我得到类似
24.00000
I don't want to see the decimal points after 24, how best do you think, it can be handled?我不想看到24后的小数点,你觉得怎么处理最好?
My dto has something like我的 dto 有类似的东西
private Instant sla;
My dto is returning an Instant
, that I am very sure of.我的 dto 正在返回一个
Instant
,我非常确定。 I want to display just the minute and send just the minute to users in an email.我想只显示一分钟并通过电子邮件将这一分钟发送给用户。 I don't want the default representation with decimal point.
我不想要带小数点的默认表示。
instant // Represents a moment as seen in UTC, an offset of zero hours-minutes-seconds.
.atOffset( ZoneOffset.UTC ) // Returns an `OffsetDateTime` object, converting from `Instant`.
.getMinute() // Returns an `int` primitive value.
You are conflating date-time objects with text.您正在将日期时间对象与文本混为一谈。 Classes such as
Instant
are not text. Instant
等类不是文本。 These classes use their own internally defined representation of date-time values.这些类使用它们自己内部定义的日期时间值表示。 That representation is not plain text.
该表示不是纯文本。
Apparently you want to extract just the minute of the hour from an Instant
object.显然,您只想从
Instant
对象中提取小时的分钟。 That class is a basic building-block class in java.time .该类是java.time中的基本构建块类。 So convert to the more flexible
OffsetDateTime
class.所以转换为更灵活的
OffsetDateTime
类。
OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC ) ;
Extract the minute of hour.提取小时的分钟。
int minute = odt.getMinute() ;
Example:例子:
Instant
.parse( "2023-01-23T19:42:07.123456789Z" )
.atOffset( ZoneOffset.UTC )
.getMinute()
