Set a Value for JAXBElement<String>

javajaxb

提问by EdgeCase

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.

我有一个如下所示的生成类。我需要从 POJO 调用 setAmount(),但我不知道要为 arg 传递什么值。它采用 JAXBElement 类型,我还没有找到实例化它的方法。

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

我有一个 ObjectFactory,但它只创建类 CardRequest。

Can anyone suggest a way?

任何人都可以提出一种方法吗?

@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);
    }
}

You can do the following:

您可以执行以下操作:

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 ObjectFactoryclass that will create this instance of JAXBElementwith the appropriate info for you.

生成的ObjectFactory类上还应该有一个 create 方法,它将JAXBElement使用适当的信息为您创建此实例。

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


UPDATE

更新

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

如果元素定义嵌套在您的架构中,则创建方法的名称可能会更长,例如createCardRequestAmount().
