@XmlRootElement
public class Dekkey {
String keyVal;
String kek1;
public String getKek1() {
return kek1;
}
@XmlElement
public void setKek1(String kek1) {
this.kek1 = kek1;
}
public String getKeyval() {
return keyVal;
}
@XmlAttribute
public void setKeyval(String inpKey) {
this.keyVal = inpKey;
}
}
This is my code snippet, where I want to insert a sub-element called userkey to the sub-element kek1. How can I do that?
How to insert attribute value for those sub-elements? I have another class called MarshDemo
in which an object of Dekkey
is created and then setkeyVal()
function is called by passing value to the function.
The output looks like this:
<Dekkey keyVal="xer">
<kek1 keyVal="biv">
<userkey keyVal="wed">
</userkey>
</kek1>
</Dekkey>
I have omitted the getters and setters for brevity, this is what your should look like.
@XmlRootElement
public class Dekkey {
@XmlAttribute
String keyVal;
Kek1 kek1;
}
@XmlElement(name="kek1")
public class Kek1 {
@XmlAttribute
String keyVal;
UserKey userkey;
}
@XmlElement(name="userkey")
public class UserKey {
@XmlAttribute
String keyVal;
}

Dekkey
Below is how you could map your use case using MOXy's @XmlPath
extension (see: http://blog.bdoughan.com/2010/07/xpath-based-mapping.html ).
import javax.xml.bind.annotation.*;
import org.eclipse.persistence.oxm.annotations.XmlPath;
@XmlRootElement(name="Dekkey")
@XmlAccessorType(XmlAccessType.FIELD)
public class Dekkey {
@XmlAttribute
String keyVal;
@XmlPath("kek1/@keyVal")
String kek1;
@XmlPath("kek1/userkey/@keyVal")
String userKey;
}
jaxb.properties
To specify MOXy as your JAXB (JSR-222) provider you need to include a file called jaxb.properties
in the same package as your domain model with the following entry (see: http://blog.bdoughan.com/2011/05/specifying-eclipselink-moxy-as-your.html ).
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
Demo
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Dekkey.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum16248263/input.xml");
Dekkey dekkey = (Dekkey) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(dekkey, System.out);
}
}
input.xml/Output
<?xml version="1.0" encoding="UTF-8"?>
<Dekkey keyVal="xer">
<kek1 keyVal="biv">
<userkey keyVal="wed"/>
</kek1>
</Dekkey>
