{ "auibinsurancecallback": { "returninfo": { "errormessage": "", "retruncode": 0, "serialnumber": 2.0191030152849496e+21 }, "policyinfo": { "policyurl": "", "operatetime": "2019-10-16 17:20:00", "transtype": "TKTS", "flightdate": "2019-10-16", "insureno": 1910161720056066800, "flightnumber": "xxx", "agreeno": 102160199, "policyno": "", "eticketno": xxx } }} |
从效果来看，明显是第二种方法，比第一种好。
下面把代码贴出出来
第一种实现：用到的包是fastjson, jdom2

public static JSONObject xml2JSON(byte[] xml) throws JDOMException, IOException { JSONObject json = new JSONObject(); InputStream is = new ByteArrayInputStream(xml); SAXBuilder sb = new SAXBuilder(); org.jdom2.Document doc = sb.build(is); Element root = doc.getRootElement(); json.put(root.getName(), iterateElement(root)); return json; } private static JSONObject iterateElement(Element element) { List node = element.getChildren(); Element et = null; JSONObject obj = new JSONObject(); List list = null; for (int i = 0; i < node.size(); i++) { list = new LinkedList(); et = (Element) node.get(i); if (et.getTextTrim().equals("")) { if (et.getChildren().size() == 0) continue; if (obj.containsKey(et.getName())) { list = (List) obj.get(et.getName()); } list.add(iterateElement(et)); obj.put(et.getName(), list); } else { if (obj.containsKey(et.getName())) { list = (List) obj.get(et.getName()); } list.add(et.getTextTrim()); obj.put(et.getName(), list); } } return obj; } @Test public void xml1(){ String xml = 上面贴的xml; JSONObject json= null; try { json = xml2JSON(xml.getBytes()); System.out.println(json.toJSONString()); } catch (JDOMException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } |
第二种实现：用的org.json包，
在用org.json包的时候，需要把spring-boot-starter-test中的，android-json排除，要不然会报错：
java.lang.NoSuchMethodError: org.json.JSONTokener.<init>(Ljava/io/Reader;)V
java.lang.NoSuchMethodError: org.json.JSONObject.put(Ljava/lang/String;Ljava/util/Collection;)
