本篇文章主要介绍了java将XML文档转换成json格式数据的示例，希望能帮助到大家。
功能
将xml文档转换成json格式数据
说明
依赖包：
1. jdom-2.0.2.jar : xml解析工具包;
2. fastjson-1.1.36.jar : 阿里巴巴研发的高性能json工具包
程序源代码
package com.xxx.open.pay.util;
import com.alibaba.fastjson.JSONObject;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.LinkedList;
import java.util.List;

public class XmlUtil {
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;
}
public static void main(String[] args) throws JDOMException, IOException {
String xml="<?xml version=\"1.0\" encoding=\"utf-8\" ?>M05210848255000.000.5zhuxiaolongzhuxiaolong10123/callback.do订单";
JSONObject json=xml2JSON(xml.getBytes());
System.out.println(json.toJSONString());
}
}
执行结果
XML原文：
M0521084825
5000.00
0.5
xiaolong
xiaolong1
0
123
/callback.do
订单
转换后的json格式数据

"Commission": [
"0.5"
],
"CustParam": [
"123"
],
"MerchID": [

],
"NotifyUrl": [

],
"OrderNo": [

],
"TradeSummary": [

],
"UserID": [

}
}
