Java在网络服务中使用何种货币价值?
原标题:What Java type to use to represent a currency value in a web service?

I m 在 Java设立一个网络服务,由外部应用消耗,可能的话在C#中书写。 在我购买的灯塔,我有一笔总费用的货币标本。 然而,这导致以下错误:

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
java.util.Currency does not have a no-arg default constructor.

I found a Solutions,用于创建一种习俗XML改编器,处理货币标识/unmarshalling:

public class CurrencyAdapter extends XmlAdapter<String,Currency> {
  public Currency unmarshal(String val) throws Exception {
    return Currency.getInstance(val);
  }
  public String marshal(Currency val) throws Exception {
    return val.toString();
  }
}

我可否使用XML改编器,或使用大比宣言(或其他类型的)表示成本?

最佳回答

你们正在 con上一种货币(是一个指定单位)和一种成本(该单位的某些数量)。 由于货币不是数量,你可以不是一种货币。
