如果一個類@XmlElement屬性，也不能有@XmlValue財產

Question

我得到以下錯誤：

If a class has @XmlElement property, it cannot have @XmlValue property 

更新類：

@XmlType(propOrder={"currencyCode", "amount"}) 
    @XmlRootElement(name="priceInclVat") 
    @XmlAccessorType(XmlAccessType.FIELD) 
    public class PriceInclVatInfo { 

    @XmlAttribute 
    private String currency; 
    @XmlValue 
    private String currencyCode; 
    private double amount; 

    public PriceInclVatInfo() {} 

    public PriceInclVatInfo(String currency, String currencyCode, double amount) { 
     this.currency = currency; 
     this.currencyCode = currencyCode; 
     this.amount = amount; 
    } 

    public String getCurrency() { 
     return currency; 
    } 

    public void setCurrency(String currency) { 
     this.currency = currency; 
    } 

    public String getCurrencyCode() { 
     return currencyCode; 
    } 

    public void setCurrencyCode(String currencyCode) { 
     this.currencyCode = currencyCode; 
    } 

    public double getAmount() { 
     return amount; 
    } 

    public void setAmount(double amount) { 
     this.amount = amount; 
    } 

} 

我想才達到以下輸出，帶有元素屬性和值：

<currencyCode plaintext="£">GBP</currencyCode> 

我該如何做到這一點？如果我有@XmlRootElement（name =「priceInclVat」），可能嗎？

對於錯誤：

If a class has @XmlElement property, it cannot have @XmlValue property

既然你指定的字段訪問，默認情況下未註釋amount場被視爲具有@XmlElement。

private double amount; 

您可以執行下列操作之一：

1. 標註amount與@XmlAttribute
2. 標註amount與@XmlTransient。
3. 將@XmlAccessorType(XmlAccessType.FIELD)更改爲@XmlAccessorType(XmlAccessType.NONE)，以便只有註釋的字段被視爲映射。

How can I achieve this? Is it possible if I have @XmlRootElement(name="priceInclVat")?

可以在JAXBElement實例包的PriceInclVatInfo實例以覆蓋在根元素和封送。
