我使用spring currency formatter根据货币代码格式化值
public String format(Number number, String currencyCode)
{
CurrencyFormatter formatter = new CurrencyFormatter();
formatter.setCurrency(Currency.getInstance(currencyCode));
return formatter.print(number, Locale.getDefault());
}
因此,如果我将其称为格式(10,“GBP”),那么无论区域设置是什么,我都希望将值恢复为10.00英镑。
这可能吗?

每当您显示货币时,您需要两条信息:货币代码以及显示结果的区域设置。例如,当您在en_US语言环境中显示USD时,您希望它显示$,但是在en_AU语言环境中,您希望它显示为US $(因为澳大利亚的货币也称为“美元”,并且它们使用$符号表示AUD)。
您遇到的问题是,当您在“非主要”区域设置中显示货币时,库存Java货币格式化程序会发臭。也就是说,美国几乎所有人都希望在显示英镑和欧元时看到£和€,但是当在en_US区域显示这些货币时,库存Java库显示“GBP”和“EUR”。
我用以下代码解决了这个问题。我基本上指定了我在展示国际货币时使用的符号:
public static NumberFormat newCurrencyFormat(Currency currency, Locale displayLocale) {
NumberFormat retVal = NumberFormat.getCurrencyInstance(displayLocale);
retVal.setCurrency(currency);
//The default JDK handles situations well when the currency is the default currency for the locale
if (currency.equals(Currency.getInstance(displayLocale))) {
return retVal;
}
//otherwise we need to "fix things up" when displaying a non-native currency
if (retVal instanceof DecimalFormat) {
DecimalFormat decimalFormat = (DecimalFormat) retVal;
String correctedI18NSymbol = getCorrectedInternationalCurrencySymbol(currency, displayLocale);
if (correctedI18NSymbol != null) {
DecimalFormatSymbols dfs = decimalFormat.getDecimalFormatSymbols(); //this returns a clone of DFS
dfs.setInternationalCurrencySymbol(correctedI18NSymbol);
dfs.setCurrencySymbol(correctedI18NSymbol);
decimalFormat.setDecimalFormatSymbols(dfs);
}
}
return retVal;
}
private static String getCorrectedInternationalCurrencySymbol(Currency currency, Locale displayLocale) {
ResourceBundle i18nSymbolsResourceBundle =
ResourceBundle.getBundle("correctedI18nCurrencySymbols", displayLocale);
if (i18nSymbolsResourceBundle.containsKey(currency.getCurrencyCode())) {
return i18nSymbolsResourceBundle.getString(currency.getCurrencyCode());
} else {
return currency.getCurrencyCode();
}
}
然后我有我的属性文件(更正了I18nCurrencySymbols.properties),我在其中指定要使用的货币符号:
# Note that these are the currency symbols to use for the specified code when displaying in a DIFFERENT locale than
# the home locale of the currency. This file can be edited as needed. In addition, if in some case one specific locale
# would use a symbol DIFFERENT than the standard international one listed here, then an additional properties file
# can be added making use of the standard ResourceBundle loading algorithm. For example, if we decided we wanted to
# show US dollars as just $ instead of US$ when in the UK, we could create a file i18nCurrencySymbols_en_GB.properties
# with the entry USD=$

我对Spring不熟悉,但以下似乎是问题所在:Locale.getDefault()
。相反,请尝试使用Locale
类中定义的静态实例之一。
