为JAXBElement <String>设置值

Question

I have a generated class that looks like below. I need to call setAmount() from a POJO, but I don't know what value to pass for the arg. It takes type JAXBElement, and I haven't found a way to instantiate that.

I have an ObjectFactory, but it only creates the class CardRequest.

Can anyone suggest a way?

@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

You can do the following:

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

There should also be a create method on the generated ObjectFactory class that will create this instance of JAXBElement with the appropriate info for you.

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

UPDATE

If the element definition is nested within your schema the name of the create method might be longer such as createCardRequestAmount() .
