本文介绍了java将XML文档转换成json格式数据的示例，分享给大家，具体如下：
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;/** * Created by [email protected] on 2015/5/19. */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/" ?><MoBaoAccount MessageType=/"UserMobilePay/" PlatformID=/"b2ctest/"><OrderNo>M20150521084825</OrderNo><TradeAmt>5000.00</TradeAmt><Commission>0.5</Commission><UserID>zhuxiaolong</UserID><MerchID>zhuxiaolong1</MerchID><tradeType>0</tradeType><CustParam>123</CustParam> <NotifyUrl>http://mobaopay.com/callback.do</NotifyUrl><TradeSummary>订单</TradeSummary></MoBaoAccount>"; JSONObject json=xml2JSON(xml.getBytes()); System.out.println(json.toJSONString()); }}
执行结果
XML原文：
<?xml version="1.0" encoding="utf-8" ?><MoBaoAccount MessageType="UserMobilePay" PlatformID="b2ctest"> <OrderNo>M20150521084825</OrderNo> <TradeAmt>5000.00</TradeAmt> <Commission>0.5</Commission> <UserID>xiaolong</UserID> <MerchID>xiaolong1</MerchID> <tradeType>0</tradeType> <CustParam>123</CustParam> <NotifyUrl>http://mobaopay.com/callback.do</NotifyUrl> <TradeSummary>订单</TradeSummary></MoBaoAccount>
转换后的json格式数据
{ "MoBaoAccount": { "Commission": [ "0.5" ], "CustParam": [ "123" ], "MerchID": [ "zhuxiaolong1" ], "NotifyUrl": [ "http://mobaopay.com/callback.do" ], "OrderNo": [ "M20150521084825" ], "TradeAmt": [ "5000.00" ], "TradeSummary": [ "订单" ], "UserID": [ "zhuxiaolong" ], "tradeType": [ "0" ] }}以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持武林网。
