java将XML文档转换成json格式数据

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;/** * 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"    ]  }}
