I'm trying to convert the XML text to a Java object, but there is a number in the prQueryStatus
XML attribute. The type of the Java field is an enum
. Is there a way for JAXB to choose my enum
?
Strxml:
<custom prQueryStatus="1" ></custom>
faulty row:
CustAttrPrQuery custom = (CustAttrPrQuery)XmlOperations.deserializeFromXML(CustAttrPrQuery.class, strXmlCustom);
XmlOperations.deserializeFromXML():
public static Object deserializeFromXML(Class obj, String strXml) {
Object result = null;
JAXBContext jaxbContext;
try {
jaxbContext = JAXBContext.newInstance(obj);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
StringReader reader = new StringReader(strXml);
result = unmarshaller.unmarshal(reader);
return result;
} catch (JAXBException e) {
return new String("-3 JAXB deSerialize Error");
}
}
CustAttrPrQuery:
@XmlAccessorType(javax.xml.bind.annotation.XmlAccessType.FIELD)
@XmlRootElement(name = CustAttrPrQuery.RootElement)
public class CustAttrPrQuery {
public final static String RootElement = "custom";
@javax.xml.bind.annotation.XmlAttribute
private PrQueryStatus prQueryStatus = PrQueryStatus.NONE;
public PrQueryStatus getPrQueryStatus() {
return prQueryStatus;
}
public void setPrQueryStatus(PrQueryStatus prQueryStatus) {
this.prQueryStatus = prQueryStatus;
}
}
enum:
public enum PrQueryStatus {
NONE,
ACIK,
TUMU
}
You need to annotate your enum type with @XmlEnum
and its constants with @XmlEnumValue
, so that JAXB will know how to map from XML attributes ( "0"
, "1"
, "2"
) to the enum constants ( NONE
, ACIK
, TUMU
):
@XmlEnum
public enum PrQueryStatus {
@XmlEnumValue("0") NONE,
@XmlEnumValue("1") ACIK,
@XmlEnumValue("2") TUMU
}
