Question

我正在使用JAXB从XSD生成POJO。由于某些原因，生成的POJO具有JAXBElement<CustomObject>作为属性。

public class ResponsePackageType{

   protected JAXBElement<? extends ResponseType> response;
   ....
}

多个类正在扩展ResponseType，但我只想映射其中一种类型，而Orika在识别此属性时遇到问题。

我的代码：

JAXBElement<ResponsePackageType> feed = (JAXBElement<ResponsePackageType>) unmarshaller.unmarshal(new FileInputStream( "input.xml" ));

MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();

Type<JAXBElement<ResponsePackageType>> respPackageType = new TypeBuilder<JAXBElement<ResponsePackageType>>(){}.build();

Type<JAXBElement<SpecialResponseType>> spRespType = new TypeBuilder<JAXBElement<SpecialResponseType>>(){}.build();

mapperFactory.classMap(respPackageType, respPackageType)
        .fieldMap("response", "response")
        .aElementType(spRespType )
        .bElementType(spRespType )
        .add()
        .byDefault().register();

MapperFacade mapper = mapperFactory.getMapperFacade();

mapper.map(feed, objectFactory.createResponsePackage(null));

例外：

Exception in thread "main" java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.TypeVariableImpl cannot be cast to java.lang.Class

    at ma.glasnost.orika.metadata.ClassMapBuilder.fieldMap(ClassMapBuilder.java:379)

我该如何解决这个问题？我应该使用propertyResolverStrategy吗？

Orika映射到JAXBElement＆lt;＆gt;
