Invalid byte 1 of 1byte UTF8 sequence（XML读取异常）

XML读取异常Invalid byte 1 of 1-byte UTF-8 sequence.

用xstream进行JavaBean与xml之间的转换，无法设定字符集编码格式，会导致上述异常。

解决方法：org.w3c.dom(java dom)解析xml文档，在此仅列出write方法：

public static void write(String xmlFile, String encoding)
            throws ParserConfigurationException, FileNotFoundException,
            TransformerException, UnsupportedEncodingException {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document document = builder.newDocument();
        Element root = document.createElement("sememewords");
        document.appendChild(root);

        Element e = document.createElement("sememeword");
        e.setTextContent("java dom Test");
        root.appendChild(e);

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer transformer = tf.newTransformer();
        DOMSource source = new DOMSource(document);
        transformer.setOutputProperty(OutputKeys.ENCODING, "utf8");
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        PrintWriter pw = new PrintWriter(
                new BufferedWriter(new OutputStreamWriter(new FileOutputStream(
                        xmlFile), encoding)));
        StreamResult result = new StreamResult(pw);
        transformer.transform(source, result);
        pw.flush();
        pw.close();
    }
