java xml转为json的两种方法
<?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：
{
"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：
{
"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;)
<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();
