Java 单字符串对象unmarshal提供UnmarshaleException

我只是想解组一个简单的xml字符串

<?xml version="1.0" ?><error>No images were found for the pro(s) entered.</error>

试着这样做：

try{
    JAXBContext jaxbContext = JAXBContext.newInstance(String.class);
    Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
    StreamSource reader = new StreamSource(new StringReader(output));
    JAXBElement<String> error = unmarshaller.unmarshal(reader, String.class);

    RateQuoteError rateQuoteError = new RateQuoteError(error.getValue);
    List<RateQuoteError> errorsList = new ArrayList<RateQuoteError>();
    errorsList.add(rateQuoteError);
    getPODResponse.setRateQuoteErrors(errorsList);
} catch(UnmarshalException ume2) {
    ume2.printStackTrace();
} catch(Exception e) {
    e.printStackTrace();
}

我看到您在RateQuoteError对象上使用了未经签名的字符串。你的RateQuoteError看起来怎么样？实际上，您可以使用JAXB将其直接解组到对象，并对RateQuoteError对象进行正确的注释：

有关注释，请查看以下内容：

RateQuoteError rateQuoteError = (RateQuoteError) unmarshaller.unmarshal(reader);
