没有为属性 [CO] 提供转化价值

Question

我有一个 xsd，它包含一个实体 Taddress，该实体 Taddress 具有一个枚举类型的属性 country_code。我无法将 xml 编组出根实体，因为它会引发如下异常

javax.xml.bind.MarshalException - 带有链接异常：[异常 [EclipseLink-25003] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b)： org.eclipse.persistence.exceptions.XMLMarshalException 异常 说明：编组内部对象时发生错误 异常：异常 [EclipseLink-115]（Eclipse 持久性服务 - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DescriptorException 异常 说明：没有为属性 [CO] 提供转换值。 映射： org.eclipse.persistence.oxm.mappings.XMLDirectMapping[countryCode-->country_code/text()] 描述符：XMLDescriptor(generated.TAddress --> [])] at org.eclipse.persistence.jaxb.JAXBMarshaller.marshal(JAXBMarshaller.java:403) 在 com.crrinfra.dynamicOutputgen.utils.HelloWorld.generateTransaction(HelloWorld.java:52) 在 com.crrinfra.dynamicOutputgen.utils.XMLUtilities.generateJaxBContext(XMLUtilities.java:259) 在 com.crrinfra.dynamicOutputgen.utils.DynamicXSDLoader.populateCache(DynamicXSDLoader.java:48) 在 com..crrinfra.dynamicOutputgen.DynamicOutputXSDParser.main(DynamicOutputXSDParser.java:16) 原因：异常 [EclipseLink-25003] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b)：org.eclipse.persistence.exceptions.XMLMarshalException 异常 说明：编组内部对象时发生错误 异常：异常 [EclipseLink-115]（Eclipse 持久性服务 - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DescriptorException 异常 说明：没有为属性 [CO] 提供转换值。 映射： org.eclipse.persistence.oxm.mappings.XMLDirectMapping[countryCode-->country_code/text()] 描述符：XMLDescriptor(generated.TAddress --> []) at org.eclipse.persistence.exceptions.XMLMarshalException.marshalException(XMLMarshalException.java:97) 在 org.eclipse.persistence.internal.oxm.XMLMarshaller.marshal(XMLMarshaller.java:911) 在 org.eclipse.persistence.internal.oxm.XMLMarshaller.marshal(XMLMarshaller.java:848) 在 org.eclipse.persistence.jaxb.JAXBMarshaller.marshal(JAXBMarshaller.java:401) ... 4 更多

    System.out.println(enumMappings.isDirectToFieldMapping());
    JAXBMarshaller marshaller = jaxbContext.createMarshaller();
    marshaller.marshal(entity, System.out);
}

}

请告知如何设置属性。我已经上传了这个问题的xsd

我找到了我的问题的答案，因此想关闭这个帖子。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;
}
}
