Question

我有一个xsd，它包含一个实体Taddress，它具有一个具有枚举类型的属性country_code。我无法将xml编组出根实体，因为它会抛出异常，如下所示

javax.xml.bind.MarshalException - 链接异常：[Exception [EclipseLink-25003]（Eclipse Persistence Services - 2.5.0.v20130507-3faac2b）： org.eclipse.persistence.exceptions.XMLMarshalException异常说明：编组对象内部时发生错误例外：异常[EclipseLink-115]（Eclipse持久性服务 - 2.5.0.v20130507-3faac2b）：org.eclipse.persistence.exceptions.DescriptorException异常描述：没有为属性[CO]提供转换值。制图： org.eclipse.persistence.oxm.mappings.XMLDirectMapping [COUNTRYCODE - ＆GT; COUNTRY_CODE /文本（）] 描述符：XMLDescriptor（generated.TAddress - ＆gt; []）] 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）引起：异常[EclipseLink-25003]（Eclipse Persistence Services - 2.5.0.v20130507-3faac2b）：org.eclipse.persistence.exceptions.XMLMarshalException异常说明：编组对象内部时发生错误例外：异常[EclipseLink-115]（Eclipse持久性服务 - 2.5.0.v20130507-3faac2b）：org.eclipse.persistence.exceptions.DescriptorException异常描述：没有为属性[CO]提供转换值。制图： org.eclipse.persistence.oxm.mappings.XMLDirectMapping [COUNTRYCODE - ＆GT; COUNTRY_CODE /文本（）] 描述符：XMLDescriptor（generated.TAddress - ＆gt; []）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） ......还有4个

    marshaller.marshal(entity, System.out);

请告知如何设置酒店。我已经用这个问题上传了xsd

我找到了问题的答案，因此想到关闭这个帖子。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;
}
}

没有为属性[CO]
