问题
I'm using formatNumber as follows:
<fmt:formatNumber value="${amount}" type="currency" currencyCode="${currencyCode}" var="amt" />
If I'm in locale en_US and the currency code is EUR I get EUR as the symbol, but if I'm in locale en_GB I get €. Why is the locale taken into account? Shouldn't EUR always convert into €? Is there anyway to get the behavior I'm expecting using formatNumber?
回答1:
Locale is taken into acount so the output makes sense to the user.
As a silly American (who lives in the en_US locale) I have no idea what that funky symbol means.
EUR makes perfect sense to me.
A quick google suggests you can set the currencySymbol attribute to whatever you want:
<fmt:formatNumber value="${amount}" type="currency" currencySymbol="FOO" currencyCode="${currencyCode}" var="amt" />
