推荐答案

不幸的是标准格式化方法不允许您这样做。乔达也不是。我想你将不得不通过一个简单的后格式替换来处理你的格式化日期。

Unfortunately the standard formatting methods don't let you do that. Nor does Joda. I think you're going to have to process your formatted date by a simple post-format replace.

String str = oldstr.replace("AM", "am").replace("PM","pm");

您可以使用 replaceAll（）方法使用regepxs，但我认为上面的内容可能就足够了。我不做毯子 toLowerCase（）因为如果你将来更改格式字符串以包含（比如说），这可能会搞砸格式化月份名称或类似名称。

You could use the replaceAll() method that uses regepxs, but I think the above is perhaps sufficient. I'm not doing a blanket toLowerCase() since that could screw up formatting if you change the format string in the future to contain (say) month names or similar.
