如何在Java中将未格式化的字符串转换为日期时间对象? [英] How to convert a non-formatted string to date time object in Java?

问题描述

我们的一堆sql迁移文件都按照惯例"V201801011200__migration.sql"命名，我被分配编写一个Java方法来选择最新的迁移.我想通过将"201801011200"解析为Java Datetime(或Datetime不支持此字符串格式的其他类似对象)来实现.

A bunch of our sql migration files are named by the convention "V201801011200__migration.sql", and I've been assigned to write a java method to pick the latest migration. I want to do so by parsing the "201801011200" into a Java Datetime (or other similar object if this string's format isn't supported by Datetime).

我将如何去做?请注意，我无法将这些迁移文件重命名为"2018-01-01-12:00"，等等.

How would I go about doing that? Please note that I am unable to rename these migration files into "2018-01-01-12:00", etc.

推荐答案

一个简单的时间字符串将是:

A simple string-to-time would be:

String timeString="201801011200";
SimpleDateFormat timeStringFormat = new SimpleDateFormat( "yyyyMMddHHmm" ) ;
Date time = timeStringFormat.parse(timeString);
System.out.println(time) ;
