map 转换 xml ； xml转map

 public class MessageKit {

     public static String map2xml(Map<String, String> map) throws IOException {
         Document d = DocumentHelper.createDocument();
         Element root = d.addElement("xml");
         Set<String> keys = map.keySet();
         for(String key:keys) {
             root.addElement(key).addText(map.get(key));
         }
         StringWriter sw = new StringWriter();
         XMLWriter xw = new XMLWriter(sw);
         xw.setEscapeText(false);
         xw.write(d);
         return sw.toString();
     }
 }

测试方法：

     @Test
     public void testMsg() {
         try {
             Map<String,String> maps = new HashMap<String, String>();
             maps.put("123", "abc");
             maps.put("bcd", "222");
             maps.put("bcd", "<abc>ddd</abc>");
             System.out.println(MessageKit.map2xml(maps));
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

xml格式字符串转map

xml格式字符串：

<xml><ToUserName><![CDATA[gh_46265bed77c6]]></ToUserName><FromUserName><![CDATA[oUigKxHuNI-QMHKzvyYpw1lCY8VQ]]></FromUserName><CreateTime>1459927356</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[sdf]]></Content><MsgId>6270340248959115708</MsgId></xml>

     public static Map<String,String> reqMsg2Map(HttpServletRequest req) throws IOException {
         String xml = req2xml(req);
         System.out.println(xml);
         try {
             Map<String,String> maps = new HashMap<String, String>();
             Document document = DocumentHelper.parseText(xml);
             Element root = document.getRootElement();
             List<Element> eles = root.elements();
             for(Element e:eles) {
                 maps.put(e.getName(), e.getTextTrim());
             }
             return maps;
         } catch (DocumentException e) {
             e.printStackTrace();
         }
         return null;
     }
