没有为属性 [CO] 提供转化值

Question

我有一个 xsd，它包含一个实体地址，它有一个属性 country_code，它有枚举类型。我无法从根实体中编组 xml，因为它会抛出如下异常

javax.xml.bind.MarshalException - with linked exception: [Exception [EclipseLink-25003] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.XMLMarshalException Exception Description: An error occurred marshalling the object Internal Exception: Exception [EclipseLink-115] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DescriptorException Exception Description: No conversion value provided for the attribute [CO].

public static void generateTransaction(DynamicJAXBContext jaxbContext) throws JAXBException, NoSuchFieldException, SecurityException{
    DynamicEntity entity = jaxbContext.newDynamicEntity("generated.Report");
    DynamicType type = jaxbContext.getDynamicType("generated.Report");

    DynamicEntity childEntity3 = jaxbContext.newDynamicEntity("generated.TAddress");
    DynamicType type1 = jaxbContext.getDynamicType("generated.TAddress");
    childEntity3.set("addressType", "M");
    childEntity3.set("address", "XXXX");
    childEntity3.set("town", "XXX");
    childEntity3.set("city", "XXXXX");
    childEntity3.set("zip", "751006");
    childEntity3.set("countryCode", "CO");
    childEntity3.set("state", "OD");
    childEntity3.set("comments", "Permanent Address");
    entity.set("location", childEntity3);

    XMLDirectMapping enumMappings = (XMLDirectMapping) ((DynamicTypeImpl) type1).getMapping("countryCode");
    System.out.println(enumMappings.isDirectToFieldMapping());
    JAXBMarshaller marshaller = jaxbContext.createMarshaller();
    marshaller.marshal(entity, System.out);
}

}

请指教如何设置属性。我已经上传了 xsd 这个问题

我找到了问题的答案，因此想关闭此线程。我很乐意收到有关此方法的反馈

public class EnumAttributeHandler implements IAttributeHandler {    
DynamicTypeImpl typeAttr;
public EnumAttributeHandler(DynamicTypeImpl typeAttr) {
    // TODO Auto-generated constructor stub
    this.typeAttr=typeAttr;
}
@Override
public DynamicEntity attributeSetter(CRROutputAttributePojo attrPojo, DynamicEntity currentEntitytag, HashMap<String, Object> params,String setterValue) throws CRROutputGenException {
    // TODO Auto-generated method stub
    XMLDirectMapping enumMappings = (XMLDirectMapping) (typeAttr)
            .getMapping(attrPojo.getActualAttrName());
    EnumTypeConverter converter=null;
    if(enumMappings.getConverter() instanceof EnumTypeConverter)
        converter = (EnumTypeConverter) enumMappings.getConverter();
    else 
        throw new CRROutputGenException("Invalid type of converter");
    try {
        if (setterValue != null) {
            Object enumField = ((DynamicJAXBContext) params.get("jaxbContext")).getEnumConstant(converter.getEnumClassName().toString(), setterValue);
            currentEntitytag.set(attrPojo.getActualAttrName(), enumField);
        }
    }catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        throw new CRROutputGenException(e.getMessage());
    }
return  currentEntitytag;
}
}
