1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
<?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>"; |
先来看效果，效果一：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 |
{ "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" ] } ] } } |
效果二：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
{ "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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 |
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;)

1 2 3 4 5 6 7 8 9 10 11 |
<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：
|
1 2 3 4 5 6 7 |
org.json.JSONObject xmlJSONObj = null ; try { xmlJSONObj = XML.toJSONObject(xml); log.debug( "json:" + xmlJSONObj.toString() ); } catch (JSONException e) { e.printStackTrace(); } |
