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：
1 public static void write(String xmlFile, String encoding) 2 throws ParserConfigurationException, FileNotFoundException, 3 TransformerException, UnsupportedEncodingException { 4 DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 5 DocumentBuilder builder = factory.newDocumentBuilder(); 6 Document document = builder.newDocument(); 7 Element root = document.createElement("sememewords"); 8 document.appendChild(root); 9 10 Element e = document.createElement("sememeword"); 11 e.setTextContent("java dom Test"); 12 root.appendChild(e); 13 14 TransformerFactory tf = TransformerFactory.newInstance(); 15 Transformer transformer = tf.newTransformer(); 16 DOMSource source = new DOMSource(document); 17 transformer.setOutputProperty(OutputKeys.ENCODING, "utf8"); 18 transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 19 PrintWriter pw = new PrintWriter( 20 new BufferedWriter(new OutputStreamWriter(new FileOutputStream( 21 xmlFile), encoding))); 22 StreamResult result = new StreamResult(pw); 23 transformer.transform(source, result); 24 pw.flush(); 25 pw.close(); 26 }
