生成xml

/** * 根据参数生成XML字符串 *  * @param params * @return */public String getXMLString(Map<String, String> params) {StringBuffer sb = new StringBuffer();sb.append("<xml>\n");for (String key : params.keySet()) {sb.append("<" + key + ">");sb.append(params.get(key));sb.append("</" + key + ">\n");}sb.append("</xml>");return sb.toString();}

map中key存元素名 value存元素中的值
