Affects: \5.2.2

we usually inject an array use comma like this：

key=A,B,C

@Value("${key}")
String[] keys;

but can't inject an array like below

origin=http://domainA.com,http://domainB.com

only key have one element, below SpEL can work fine, if key have more than 2 elements, it won't work

@CrossOrigin(value = "${origin}")

Or

@CrossOrigin(value = "#{'${origin}'.split(',')}")

Can provide any advice?
