1 java xml转为json的方法
1.1 fastjson和jdom2进行转化
<?xml version="1.0" encoding="utf-8" ?> <auibinsurancecallback> <policyinfo> <transtype>TKTS</transtype> <eticketno>xxx</eticketno> <flightnumber>xxx</flightnumber> <flightdate>2019-10-16</flightdate> <operatetime>2019-10-16 17:20:00</operatetime> <insureno>1910161720056066735</insureno> <agreeno>102160199</agreeno> <policyno> </policyno> <policyurl> <!--[CDATA[]]--> </policyurl> </policyinfo> <returninfo> <serialnumber>2019103015284949545354 </serialnumber> <retruncode>0</retruncode> <errormessage> <!--[CDATA[xxx]]--> </errormessage> </returninfo> </auibinsurancecallback>";
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(); } }
实现效果：
{ "auibinsurancecallback": { "returninfo": [ { "retruncode": [ "0" ], "serialnumber": [ "2019103015284949545354" ] } ], "policyinfo": [ { "operatetime": [ "2019-10-16 17:20:00" ], "transtype": [ "TKTS" ], "flightdate": [ "2019-10-16" ], "insureno": [ "1910161720056066735" ], "flightnumber": [ "xxx" ], "agreeno": [ "102160199" ], "eticketno": [ "xxxx" ] } ] } }
比较丑全是list的样子,也能用
1.2 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.(Ljava/io/Reader;)V
java.lang.NoSuchMethodError: org.json.JSONObject.put(Ljava/lang/String;Ljava/util/Collection;)
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>com.vaadin.external.google</groupId> <artifactId>android-json</artifactId> </exclusion> </exclusions> </dependency>
实现方法简单：
org.json.JSONObject xmlJSONObj = null; try { xmlJSONObj = XML.toJSONObject(xml); log.debug("json:" + xmlJSONObj.toString() ); } catch (JSONException e) { e.printStackTrace(); }
实现效果：
{ "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 } } }
2 java json格式转xml格式
2.1 使用 jdom 进行转换
描述：
xml转json org.jdom
用 dom 提取节点 转成map
json 转 xml com.alibaba.fastjson.JSONObject
