java.time.LocalDate到java.util.Date [英] java.time.LocalDate to java.util.Date

问题描述

从java.time.LocalDate转换为java.util.Date的最佳方法是什么?

Date.from(dateToReturn.atStartOfDay(ZoneId.systemDefault()).toInstant()

我一直在尝试这种方法，但是尽管可以正确地转换日期和年份，但似乎不能正确显示时间.

更新:java.time.LocalDate不保存时间信息只是使用了java.time.LocalDateTime，一切正常.

解决方案

LocalDate ld = ...;
Instant instant = ld.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date res = Date.from(instant);

查看此博客文章，在Date和java8 java.time.LocalDateTime之间进行转换，LocalDate和LocalTime .

What is the best way to convert from java.time.LocalDate to java.util.Date ?

Date.from(dateToReturn.atStartOfDay(ZoneId.systemDefault()).toInstant()

I have been trying this one but does not seem to work correct with the time although converts the date month and year correctly.

Update : java.time.LocalDate does not save time informations Just used java.time.LocalDateTime instead and everything works fine.

解决方案

LocalDate ld = ...;
Instant instant = ld.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date res = Date.from(instant);
