java使用json-lib将xml转换为json

java将xml转换为json的另一种方法。需要用到的类库：

请自己注意添加以上类库的依赖包。

java代码：

package com.mibridge.util;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.InputStream;

import net.sf.json.JSON;
import net.sf.json.xml.XMLSerializer;

public class ConvertXMLtoJSON {
    public static void main(String[] args) throws Exception {
        String xml = getXMLString("soap-origin.xml");
        System.out.println(xml);
        XMLSerializer xmlSerializer = new XMLSerializer();
        JSON json = xmlSerializer.read(xml);
        System.out.println(json.toString(2));
    }

    private static String getXMLString(String filePath) {
        StringBuffer sb = new StringBuffer();
        BufferedReader br = null;
        String line;
        try {
            br = new BufferedReader(new FileReader(filePath));
            while (true) {
                line = br.readLine();
                if (line == null) {
                    break;
                }
                sb.append(line + "\n");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return sb.toString();
    }

}

xml文档soap-origin.xml：

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="">
<soapenv:Body>
<ns:Response xmlns:ns="">
   <ns:return>
      <ns:person>
         <ns:personName></ns:personName>
         <ns:personAge></ns:personAge>
         <ns:personAddress>
            <ns:addressType>家庭住址</ns:addressType>
            <ns:addressLine1>中国深圳</ns:addressLine1>
         </ns:personAddress>
         <ns:personAddress>
            <ns:addressType>公司地址</ns:addressType>
            <ns:addressLine1>荔香公园</ns:addressLine1>
         </ns:personAddress>
      </ns:person>
   </ns:return>
</ns:Response>
</soapenv:Body>
</soapenv:Envelope>

输出的json：

{
  "@xmlns:soapenv": "",
  "soapenv:Body": {"ns:Response":   {
    "@xmlns:ns": "",
    "ns:return": {"ns:person":     {
      "ns:personName": null,
      "ns:personAge": null,
      "ns:personAddress":       [
                {
          "ns:addressType": "家庭住址",
          "ns:addressLine1": "中国深圳"
        },
                {
          "ns:addressType": "公司地址",
          "ns:addressLine1": "荔香公园"
        }
      ]
    }}
  }}
}
