在工作中，经常碰到XML转为JSON或者JSON转为XML，在这过程中有时嵌套很多层，容易错误，我把实现的代码分享出来，希望对有用到的人提供借鉴。
1.把XML转为JSON格式
- <span style="font-size:18px;">@SuppressWarnings("rawtypes")
- public static String xmlToJSON(String xml,int jsonType) {
- JSONObject obj = new JSONObject();
- try {
- InputStream is = new ByteArrayInputStream(xml.getBytes("utf-8"));
- SAXBuilder sb = new SAXBuilder();
- Document doc = sb.build(is);
- Element root = doc.getRootElement();
- Map map=iterateElement(root);
- obj.put(root.getName(),map);
- return obj.toString();
- } catch (Exception e) {
- e.printStackTrace();
- return null;
- }
- }
-
-
- @SuppressWarnings({ "unchecked", "rawtypes" })
- private static Map iterateElement(Element root) {
- List childrenList = root.getChildren();
- Element element = null;
- Map map = new HashMap();
- List list = null;
- for (int i = 0; i < childrenList.size(); i++) {
- list = new ArrayList();
- element = (Element) childrenList.get(i);
- if(element.getChildren().size()>0){
- if(root.getChildren(element.getName()).size()>1){
- if (map.containsKey(element.getName())) {
- list = (List) map.get(element.getName());
- }
- list.add(iterateElement(element));
- map.put(element.getName(), list);
- }else{
- map.put(element.getName(), iterateElement(element));
- }
- }else {
- if(root.getChildren(element.getName()).size()>1){
- if (map.containsKey(element.getName())) {
- list = (List) map.get(element.getName());
- }
- list.add(element.getTextTrim());
- map.put(element.getName(), list);
- }else{
- map.put(element.getName(), element.getTextTrim());
- }
- }
- }
-
- return map;
- }
-
-
-
- public static void main(String[] args) throws ParseException
- {
- String xml="<ROOT>"+
- "<Status>00</Status>"+
- "<ErrorMsg></ErrorMsg>"+
- "<Data>"+
- "<Row>"+
- "<PERSONID>35020500200610000000000701355116</PERSONID>"+
- "<XM>吴聪楠</XM><SFZH>350624198908052530</SFZH>"+
- "</Row>"+
- "<Row>"+
- "<PERSONID>35020500200610000000000701355117</PERSONID>"+
- "<XM>吴聪楠2</XM><SFZH>350624198908052531</SFZH>"+
- "</Row>"+
- "</Data>"+
- "</ROOT>";
-
-
- String str=Xml2JsonUtil.xmlToJSON(xml,1);
- System.out.println(str);
- }</span>
原来的格式：
<ROOT><Status>00</Status><ErrorMsg></ErrorMsg><Data><Row><PERSONID>35020500200610000000000701355116</PERSONID><XM>吴聪楠</XM><SFZH>350624198908052530</SFZH></Row><Row><PERSONID>35020500200610000000000701355117</PERSONID><XM>吴聪楠2</XM><SFZH>350624198908052530</SFZH></Row></Data></ROOT>
转换完的格式：
<span style="font-size:18px;">{"ROOT":{"Data":{"Row":[{"SFZH":"350624198908052530","XM":"吴聪楠","PERSONID":"35020500200610000000000701355116"},{"SFZH":"350624198908052530","XM":"吴聪楠2","PERSONID":"35020500200610000000000701355117"}]},"Status":"00","ErrorMsg":""}}</span>
2.JSON 转换为XML格式
- <span style="font-size:18px;">public static String JsonToXml(Object json)
- {
- if(json==null){
- return null;
- }else{
- Element elements=new Element("xml");
- getXMLFromObject(json,"xml",elements);
- XMLOutputter xmlOut = new XMLOutputter();
- String res=xmlOut.outputString(elements);
- return res;
- }
- }
-
-
- private static void getXMLFromObject(Object obj,String tag,Element parent)
- {
- if(obj==null)
- return;
- Element child;
- String eleStr;
- Object childValue;
- if(obj instanceof JSONObject)
- {
- JSONObject jsonObject=(JSONObject)obj;
- for(Object temp:jsonObject.keySet())
- {
- eleStr=temp.toString();
- childValue=jsonObject.get(temp);
- child=new Element(eleStr);
- if(childValue instanceof JSONArray)
- getXMLFromObject(childValue,eleStr,parent,count);
- else{
- parent.addContent(child);
- getXMLFromObject(childValue,eleStr,child,count);
- }
- }
- }else if(obj instanceof JSONArray){
- JSONArray jsonArray=(JSONArray)obj;
- for(int i=0;i<jsonArray.size();i++)
- {
- childValue=jsonArray.get(i);
- child=new Element(tag);
- parent.addContent(child);
- getXMLFromObject(childValue,tag,child,count);
- }
- }else if(obj instanceof Date){
- SimpleDateFormat sf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
- parent.setText(sf.format((Date)obj));
- }else{
- parent.setText(obj.toString());
- }
- }
-
-
- public static void main(String[] args) throws ParseException
- {
- JSONObject rootObject=new JSONObject();
-
- JSONArray dataArray=new JSONArray();
- JSONObject dataObject1=new JSONObject();
- dataObject1.put("PERSONID", "35020500200610000000000701355117");
- dataObject1.put("XM", "吴聪楠");
- dataObject1.put("SFZH","350624198908052530");
- dataArray.add(dataObject1);
- JSONObject dataObject2=new JSONObject();
- dataObject2.put("PERSONID", "35020500200610000000000701355116");
- dataObject2.put("XM", "吴聪楠2");
- dataObject2.put("SFZH","350624198908052531");
- dataArray.add(dataObject2);
-
- JSONObject dataRootObject=new JSONObject();
- dataRootObject.put("Row", dataArray);
- JSONObject dataObject=new JSONObject();
- dataObject.put("Status", "00");
- dataObject.put("ErrorMsg", "");
- dataObject.put("Data",dataRootObject);
- rootObject.put("ROOT", dataObject);
-
- System.out.println(rootObject.toString());
- System.out.println(JsonToXml(rootObject));
-
- }</span>
原来的格式：
{"ROOT":{"Status":"00","ErrorMsg":"","Data":{"Row":[{"PERSONID":"35020500200610000000000701355117","XM":"吴聪楠","SFZH":"350624198908052530"},{"PERSONID":"35020500200610000000000701355116","XM":"吴聪楠2","SFZH":"350624198908052531"}]}}}
转换完的格式：
<ROOT><Status>00</Status><ErrorMsg></ErrorMsg><Data><Row><PERSONID>35020500200610000000000701355117</PERSONID><XM>吴聪楠</XM><SFZH>350624198908052530</SFZH></Row><Row><PERSONID>35020500200610000000000701355116</PERSONID><XM>吴聪楠2</XM><SFZH>350624198908052531</SFZH></Row></Data></ROOT>
