如何在 JSP 中动态设置标头值
我有一个创建 Excel 文档的 JSP 文件.
I have a JSP file which creates an Excel document.
我想动态设置要下载的文件名.
I want to dynamically set the name of the file to be downloaded.
这就是我将文件名设置为test.xsl"的方式:
This is how I set the file name to "test.xsl":
<% response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=" + "test.xsl" );
%>
如何将文件名设置为 test-${今天的日期}.xsl(即 test-20100805.xsl)?
How can I set the file name to be test-${today's date}.xsl ( i.e. test-20100805.xsl ) ?
推荐答案
String fname = MessageFormat.format(
"test-{0,date,yyyyMMdd}.xsl", new Object [] { new Date() } );
response.setHeader("Content-Disposition","attachment; filename=" + fname );
我认为这应该适合你.
大括号中的文本告诉 MessageFormat 类从给定数组中插入值 0，使用格式将其格式化为 dateyyyyMMdd(例如 20161231 表示 2016 年 12 月 31 日).
The text in the braces tells the MessageFormat class to insert value 0 from the given array, format it as a date using the format yyyyMMdd (e.g. 20161231 for Dec 31st 2016).
