为JAXBElement <String>设置值

Question

我有一个生成的类,如下所示.我需要从POJO调用setAmount(),但我不知道为arg传递什么值.它需要类型JAXBElement,我还没有找到实例化它的方法.

我有一个ObjectFactory,但它只创建了CardRequest类.

谁能提出建议？

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "amount",
})
@XmlRootElement(name = "card-request")
public class CardRequest {

    @XmlElementRef(name = "amount", namespace = "http://mycompany/services", type = JAXBElement.class)
    protected JAXBElement<String> amount;

    public JAXBElement<String> getAmount() {
        return amount;
    }

    public void setAmount(JAXBElement<String> value) {
        this.amount = ((JAXBElement<String> ) value);
    }
}

Answer 1

您可以执行以下操作:

JAXBElement<String> jaxbElement = 
    new JAXBElement(new QName("http://mycompany/services", "amount"), String.class, "Hello World");

在生成的ObjectFactory类上还应该有一个create方法,它将JAXBElement为您创建具有相应信息的此实例.

ObjectFactory objectFactory = new ObjectFactory();
JAXBElement<String> jaxbElement = objectFactory.createAmount("Hello World");

UPDATE

如果元素定义嵌套在模式中,则create方法的名称可能会更长,例如createCardRequestAmount().
