Question

我正在利用日本宇宙航空研究开发机构的说明。我希望,信用卡内福的展示不会展示出信用卡。 FYI CreditCard 信息是一种复杂的物体。

@XmlRootElement
public Class Notification{
private String notifDate;
private CreditCardInfo ccInfo;
}

public Class CreditCardInfo{
private int ccNum;
private String expiryMonth;
}

希望产出

<notification>
<date>04/29/11</date>
<ccNum>3456</ccNum>
<expiry_month>November</expiry_month>
</notification>

Regards, -Anand

You could use the @XmlPath extension in EclipseLink JAXB (MOXy) to handle this use case. Note: I m the MOXy lead.

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

import org.eclipse.persistence.oxm.annotations.XmlPath;

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Notification{

    @XmlElement(name="date")
    private String notifDate;

    @XmlPath(".")
    private CreditCardInfo ccInfo;

}

<>CreditCardInfo

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;

@XmlAccessorType(XmlAccessType.FIELD)
public class CreditCardInfo{

    private int ccNum;

    @XmlElement(name="expiry_month")
    private String expiryMonth;

}

<>Demo

import java.io.File;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Notification.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        Notification notification = (Notification) unmarshaller.unmarshal(new File("input.xml"));

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(notification, System.out);
    }

}

<>strong>jaxb.properties

• 利用MOXy作为你的日本宇宙航空研究开发机构提供商,需要在与你的模型班相同的一揽子方案中添加一个名为“jaxb.properties”的文件,其条目如下:

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
