Java解封字符串xml到泛型类型类

Question

我想把字符串xml转换成对象类型类。因为我有一个返回对象类型的rest服务。因为我需要根据响应字符串将响应作为动态创建的xml返回。但是，当我试图将字符串xml转换为对象类时，它显示了以下错误：

UnmarshalException：意外元素

@POST
@Path("/post")
@Consumes(MediaType.APPLICATION_JSON)
public  Object sendReqXML(RequestModel request)
{
    try {

        XmlAPI.getInstance().addHeader("Content-Type","text/xml; charset=utf-8");
        XmlAPI.getInstance().addHeader("SOAPAction",request.getAction());
        return XmlAPI.getInstance().post(request.getUrl(), request.getAction(), Parser.loadXML(request.getData()), new CallBackEpul());

    }
    catch (Exception e) {
        e.printStackTrace();
        return e.getMessage();
    }

}

 public static Object loadXMLToObject(String xml) throws Exception
{
    JAXBContext jaxbContext = JAXBContext.newInstance(Object.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
   //jaxbUnmarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

    StringReader reader = new StringReader(xml);
    Object object = (Object) jaxbUnmarshaller.unmarshal(reader);

    //LOGGER.info(car.toString());
    return object;
}

我发现将@produces设置为APPLICATION_XML并返回字符串就足够了：

@POST
 @Path("/post")
 @Consumes(MediaType.APPLICATION_JSON)
 @Produces (MediaType.APPLICATION_XML)
 public String sendReqXML(RequestModel request)
{
    try {

        /** JSON API **/
        //JsonAPI.getInstance().addHeader("Content-Type","text/xml; charset=utf-8");
        //JsonAPI.getInstance().addHeader("SOAPAction",request.getAction());
        //JsonAPI.getInstance().post(request.getUrl(), request.getAction(), Parser.loadXML(request.getData()), new CallBackEpul());

        /** XML API **/
        XmlAPI.getInstance().addHeader("Content-Type","text/xml; charset=utf-8");
        XmlAPI.getInstance().addHeader("SOAPAction",request.getAction());
        return XmlAPI.getInstance().post(request.getUrl(), request.getAction(), Parser.loadXML(request.getData()), new CallBackEpul());

    }
    catch (Exception e) {
        e.printStackTrace();
        return "";
    }

}
