如果类具有@XmlElement属性，则它不能具有@XmlValue属性 [英] If a class has @XmlElement property, it cannot have @XmlValue property

问题描述

我收到以下错误：

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

已更新类：

    @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;
    }

}

我想获得以下输出，具有元素属性和值：

I want to achive the following output, with an element attribute and value:

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

我如何实现这一目标？是否可以使用@XmlRootElement（name =priceInclVat）？

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

推荐答案

对于错误：

如果某个类具有@XmlElement属性，则它不能具有@XmlValue属性

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

由于您已指定了字段访问权限，因此默认情况下，未注释的金额字段被视为具有 @XmlElement 。

Since you have specified field access, by default the unannotated amount field is treated as having @XmlElement.

private double amount;

您可以执行以下操作之一：

You can do one of the following:

1. 使用 @XmlAttribute

金额 >使用 @XmlTransient 注释金额。

2. 更改 @XmlAccessorType（XmlAccessType.FIELD）到 @XmlAccessorType（XmlAccessType.NONE），以便只将带注释的字段视为已映射。

1. Annotate amount with @XmlAttribute
2. Annotate amount with @XmlTransient.
3. Change@XmlAccessorType(XmlAccessType.FIELD) to @XmlAccessorType(XmlAccessType.NONE) so that only annotated fields are treated as mapped.

@XmlRootElement（name =priceInclVat）？

你可以包装<的实例code> PriceInclVatInfo 在 JAXBElement 的实例中覆盖根元素并编组该元素。

You can wrap the instance of PriceInclVatInfo in an instance of JAXBElement to override the root element and marshal that.
