  • 0

I have the following xml string. I want to convert it in to a java object, to map each tag with the fields of that object. Its better that if I can introduce different field names compared to tag name. How I can do that? I am looking on JAXB but I am still confused about parts like “ns4:response” and tags within tags. Thank you in advance…

<ns4:response>
    <count>1</count>
    <limit>1</limit>
    <offset>1</offset>
    <ns3:payload xsi:type="productsPayload">
        <products>
            <product>
                <avgRating xsi:nil="true"/>
                <brand>Candie's</brand>
                <description>
                    <longDescription>
                    long descriptions
                    </longDescription>
                    <shortDescription>
                    short description
                    </shortDescription>
                </description>

    JAXB is the Java standard (JSR-222) for converting objects to/from XML. The following should help:

    Unmarshalling from a String

    You will need to wrap the String in an instance of StringReader before your JAXB impl can unmarshal it.

    StringReader sr = new StringReader(xmlString);
JAXBContext jaxbContext = JAXBContext.newInstance(Response.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Response response = (Response) unmarshaller.unmarshal(sr);

    Different Field and XML Names

    You can use the @XmlElement annotation to specify what you want the name of the element to be. By default JAXB looks at properties. If you wish to base the mappings on the fields then you need to set @XmlAccessorType(XmlAccessType.FIELD).

    @XmlElement(name="count")
private int size;

    Namespaces

    The @XmlRootElement and @XmlElement annotations also allow you to specify namespace qualification where needed.

    @XmlRootElement(namespace="http://www.example.com")
public class Response {
}
