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,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧
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 1250052380@qq.com 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" ] } }
