[英]How can I output System.currentTimeMillis() to an ADF page?
I'm using this and it doesn't work as expected. 我正在使用它,它没有按预期工作。 I'm trying to cache bust a css file as it changes a lot and we can't always expect users to thoroughly clear their cache.
我正在尝试缓存css文件,因为它发生了很多变化,我们不能总是期望用户彻底清除其缓存。
<c:set var="buster" value="{System.currentTimeMillis()}" />
<af:resource type="css" source="/oracle/webcenter/portalapp/shared/css/maaui.css?r=${buster}"/>
Unfortunately that renders 不幸的是
<link rel="stylesheet" type="text/css" afrres="true" href="/myAccount/oracle/webcenter/portalapp/shared/css/maaui.css?r=%7BSystem.currentTimeMillis()%7D">
It doesn't execute the method. 它不执行该方法。 I tried
${}
and #{}
as well and neither seem to work for me. 我也尝试过
${}
和#{}
,但似乎都不适合我。 Can anyone help me to achieve the desired result? 谁能帮助我达到预期的效果? Basically a random string that will change each time a user visits a page.
基本上是一个随机字符串,它将在用户每次访问页面时更改。 I can easily do this in .NET but I am very new to Oracle ADF.
我可以在.NET中轻松地做到这一点,但是我对Oracle ADF还是陌生的。
Try 尝试
<c:set var="buster" value="{myBean.time}" />
<af:resource type="css" source="/oracle/webcenter/portalapp/shared/css/maaui.css?r=#{buster}"/>
And in MyBean managed backing bean 并在MyBean中管理后备bean
public long getTime()
{
return System.getCurrentTimeMillis();
}
