如何用JSTL显示ISO8601的日期？

Question

就像是？

<fmt:formatDate value="${event.starttime}" type="both"/>

Answer 1

It is not possible AFAIK. You can use the pattern attribute:

<fmt:formatDate pattern="yyyy-MM-dd'T'HH:mm:ssz" value="${event.starttime}" />

But there is not a pattern to generate ISO8601 without post-processing. You have to cook your date in the server side and show it in your view.

You might find Joda-Time library useful, as well as some blog posts like:

Answer 2

如果您不介意所有日期都是UTC（或修改后的其他硬编码时区），您可以使用：

<fmt:formatDate value="${event.starttime}" pattern="yyyy-MM-dd'T'HH:mm:ss'Z'" timeZone="UTC"/>
