JAX-WS调度响应中的编码错误

Question

我正在尝试使用JAX-WS访问Web服务：

Dispatch<Source> sourceDispatch = null;
sourceDispatch = service.createDispatch(portQName, Source.class, Service.Mode.PAYLOAD);
Source result = sourceDispatch.invoke(new StreamSource(new StringReader(req)));
System.out.println(sourceToXMLString(result));

其中：

private static String sourceToXMLString(Source result)
        throws TransformerConfigurationException, TransformerException {
    String xmlResult = null;
    try {
        TransformerFactory factory = TransformerFactory.newInstance();
        Transformer transformer = factory.newTransformer();
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        transformer.setOutputProperty(OutputKeys.METHOD, "xml");
        transformer.setOutputProperty(OutputKeys.ENCODING, "utf-8");
        OutputStream out = new ByteArrayOutputStream();
        StreamResult streamResult = new StreamResult();
        streamResult.setOutputStream(out);
        transformer.transform(result, streamResult);
        xmlResult = streamResult.getOutputStream().toString();
    } catch (TransformerException e) {
        e.printStackTrace();
    }
    return xmlResult;
}

当我在utf-8页面上打印结果时，utf-8字符无法正确显示。

由于WS可以与其他工具一起使用（返回UTF-8很好），我倾向于认为我的转换 sourceToXMLString（）存在一些问题。这会破坏我的编码吗？

尝试以下方法：

private static String sourceToXMLString(Source result) throws TransformerConfigurationException, TransformerException {

String xmlResult = null;
try {
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer transformer = factory.newTransformer();
    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    transformer.setOutputProperty(OutputKeys.METHOD, "xml");
    transformer.setOutputProperty(OutputKeys.ENCODING, "utf-8");
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    transformer.transform(result, new StreamResult(out));
    xmlResult = out.toString("UTF-8");
    // or xmlResult = new String(out.toByteArray(), "UTF-8");
} catch (TransformerException e) {
    e.printStackTrace();
}
return xmlResult; 
}
