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
需要引入 jdom 1.x 版本：
<!-- https://mvnrepository.com/artifact/org.jdom/jdom -->
<dependency>
<groupId>org.jdom</groupId>
<artifactId>jdom</artifactId>
<version>1.1.3</version>
</dependency>
