我有我的模型:
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class CustomerTest {
private Long id;
@XmlPath("contact-info/billing-address")
private AddressTest billingAddress;
@XmlPath("contact-info/shipping-address")
private AddressTest shippingAddress;
@XmlPath("FileHeader/SchemaVersion/text()")
private String schemaVersion;
}
我这样填写对象:
private void marshallCustomerTest() {
try {
JAXBContext jc = JAXBContext.newInstance(CustomerTest.class);
CustomerTest customer = new CustomerTest();
customer.setId(new Long(10));
customer.setSchemaVersion("3.2");
AddressTest billingAddress = new AddressTest();
billingAddress.setStreet("1 Billing Street");
customer.setBillingAddress(billingAddress);
AddressTest shippingAddress = new AddressTest();
shippingAddress.setStreet("2 Shipping Road");
customer.setShippingAddress(shippingAddress);
Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
m.marshal(customer, System.out);
} catch (JAXBException jex) {
jex.printStackTrace();
log.error(jex);
}
}
这将产生下一个 XML:
<customerTest xmlns:fe="http://www.facturae.es/Facturae/2009/v3.2/Facturae" xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
<id>10</id>
<contact-info>
<billing-address>
<street>1 Billing Street</street>
</billing-address>
<shipping-address>
<street>2 Shipping Road</street>
</shipping-address>
</contact-info>
<FileHeader>
<SchemaVersion>3.2</SchemaVersion>
</FileHeader>
</customerTest>
如您所见,'id' 属性没有 @XmlPath 注释,但这也存在于最终 XML 中。我知道我可以避免将 'id' 属性设置为 null 的这种行为,但我想知道是否有其他方法。关键是我的真实模型比这个大得多,我必须将很多属性设置为空。
有什么帮助吗?
