Joda Time是否已被Java 8 Date and Time API弃用？ （java.time） [英] Is Joda Time deprecated with java 8 Date and Time API? (java.time)

问题描述

如果我可以使用Java 8日期和时间API（ java.time ），是否有任何理由使用Joda Time？

我应该使用每次Java 8日期和时间？

Is there any reason to use Joda Time if I can use Java 8 Date and Time API (java.time)?
Should I use Java 8 Date and Time every time?

推荐答案

Joda-time本人的官方声明是迁移只要Java-8可用。另请参阅网站中的引用：

The official statement of the author of Joda-time himself is to migrate as soon as Java-8 is available. See also this citation from the website:

请注意，Joda-Time被认为是一个基本上完成的项目。
未计划任何重大改进。如果使用Java SE 8，请将
迁移到java.time（JSR-310）。

Note that Joda-Time is considered to be a largely "finished" project. No major enhancements are planned. If using Java SE 8, please migrate to java.time (JSR-310).

所以简短回答你的问题是：是（已弃用）。但是，请记住一些功能，如Joda - Interval 或 PeriodType 或 PeriodFormatter 在Java-8中不可用，因此您必须编写自己的部分丑陋的解决方法，另请参阅我的 SO-post 关于Joda-Time和JSR-310之间的差异。

So the short answer to your question is: YES (deprecated). However, keep in mind that some features like Joda-Interval or PeriodType or PeriodFormatter are not available in Java-8 so you have to write your own partially ugly workarounds, see also my SO-post about differences between Joda-Time and JSR-310.

Side remarks about the future of both libraries:

完成在这种情况下意味着什么？

嗯，你可以比较 Joda-issue 254 使用我的 Twitter上的小讨论。我认为人们应该对Joda-Time的任何重大改进设定他们的期望。还请考虑有关Joda-Time的未来开发资源有限（缺乏人力）。而且说实话：自2008年Joda-Time以来的大多数版本都具有bugfix版本的特性（2.0除外）。

Well, you can compare the Joda-issue 254 with my small discussion on Twitter. I think people should rather set down their expectations to any major enhancement of Joda-Time. Please also consider that the future development resources regarding Joda-Time are limited (lack of manpower). And let's be honest: Most releases since Joda-Time in year 2008 rather have the character of bugfix releases (with the exception of 2.0).

另一方面： JSR-310的创新速度也可能不会很高（因为它已经很大了，因为Oracle在这里是决定性的参与者而且日期时间库通常不被认为是任何Java发布的核心基础）。因此，未来外部库总会留出一些空间来提供缺失的功能，例如（按字母顺序排列）：

On the other side: The innovation speed of JSR-310 will probably not be very high, too (because it is already big, and because Oracle is here the decisive player and a date-time-library is in general not considered as the central cornerstone of any Java-release). So there is always some space left for an external library in the future to supply missing features, for example (in alphabetical order):

• < a href =https://github.com/ThreeTen/threeten-extra =noreferrer> Threeten-Extra （作为Basil Bourque的最爱，见他的评论）


• Time4J （我自己的扩展，2015年夏季解决了互操作性问题）

• Threeten-Extra (as the favourite of Basil Bourque, see his comment)
• Time4J (my own extension, interoperability issue solved in summer 2015)
