将Joda LocalDate或java.util.Date转换为在当天开始时有时间的LocalDateTime [英] Convert Joda LocalDate or java.util.Date to LocalDateTime having time at Start of the Day

问题描述

我正在使用Joda 2.5

I am using Joda 2.5

在将Joda LocalDate转换为LocalDateTime时遇到问题。

Facing an issue while converting the Joda LocalDate to LocalDateTime.

As ，我可以使用Time atStartOfDay将LocalDate转换为DateTime。我想通过LocalDateTime对象获得相同的功能。

As,I am able to convert LocalDate to DateTime with Time atStartOfDay. I wanted the same feature but via LocalDateTime object.

我的代码是：

假设日期来自不同的REST服务，比如说

Suppose Date is coming from different REST service , say

Date currentDate = new Date("2015-02-05");

现在这个Date被传递给另一个服务，如下所示：

And now this Date is passed to some another service as shown below :

funService(currentDate);

public funService(Date currentDate)
{
       LocalDate localDateObject = new LocalDate(date);

// Now I have to convert this Date to LocalDateTime
    LocalDateTime localDateTime = localDateObject.toDateTimeAtStartOfDay();
//But this returns DateTime Object.

// As I don't want to store the DateTime Object because it also stores the TimeZone


}

我想要LocalDateTime对象，因为我将此LocalDateTime作为时间戳存储在mysql中。

I want the LocalDateTime Object as I am storing this LocalDateTime as Timestamp in the mysql.

请提供将LocalDate转换为LocalDateTime对象的解决方案。

例如：'2015-02-01'到'2015-02 -01 00:00:01'
YYYY-MM-DD到YYYY-MM-DD HH：MM：SS：zzz

Eg : '2015-02-01' to '2015-02-01 00:00:01' YYYY-MM-DD to YYYY-MM-DD HH:MM:SS:zzz

但不是LocalDate到DateTime

But not LocalDate to DateTime

推荐答案

一旦你摆脱了时区异常，你可以假设每天都在午夜开始，所以使用：

Well once you get rid of time zone anomalies, you can probably just assume that every day starts at midnight, so use:

LocalDateTime localDateTime = localDate.toLocalDateTime(LocalTime.MIDNIGHT);

目前尚不清楚为什么你想在1秒内过去午夜结束。如果你真的想要它，创建你自己的常量 LocalTime 表示，并在上面的代码中使用它代替 MIDNIGHT 。

It's not clear why you wanted to end up at 1 second past midnight. If you really want that, create your own constant LocalTime representing that, and use it instead of MIDNIGHT in the above code.

另请注意，如果您实际上有一个日期，您可能已经丢失了信息。听起来传入的数据实际上是一个字符串 - 您最好直接将其解析为 LocalDate ，以避免时区可能导致问题。

Also note that if you've actually got a Date, you may already have lost information. It sounds like the incoming data is really a string - you'd be best off parsing that directly as a LocalDate to avoid time zones potentially causing problems.
