JSON字符串转XML写日志

做后台开发，或多或少做过集成，集成最重要的就是对数据的跟踪，日志定位分析。我们常会跟踪发放的数据是否正确，这里就涉及到将数据格式化写文件的场景。

public static String json2Xml(String jsonStr) throws DocumentException {
        XMLSerializer xmlSerializer = new XMLSerializer();
        xmlSerializer.setTypeHintsEnabled(false);
        xmlSerializer.setRootName("root");
        String sXml = "";
        String sContent = "";
        if (StringUtils.isNotBlank(jsonStr)) {
            try {
                if (jsonStr.contains("[{") && jsonStr.contains("}]")) {
                    net.sf.json.JSONArray jobj = net.sf.json.JSONArray.fromObject(jsonStr);
                    sContent = xmlSerializer.write(jobj);
                }else {
                    JSONObject jobj = JSONObject.fromObject(jsonStr);
                    sContent = xmlSerializer.write(jobj);
                }
                Document docCon = DocumentHelper.parseText(sContent);
                sContent =docCon.getRootElement().asXML().replaceAll("<e>", "").replaceAll("</e>", "");
                sXml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>"+sContent;
            } catch (Exception e) {
                e.printStackTrace();
                return null;
            }
        }
        return sXml;
    }

然后写入文件即可
org.apache.commons.io.FileUtils.writeStringToFile(dataFile, json2Xml(data), “UTF-8”);
