java将XML文档转换成json格式数据的示例

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;

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"
    ]
  }
}
