依赖的包:

json-lib-2.4-jdk15.jar

输入xml文件,输出JSON对象

Java代码



package com.cash.util;

import java.io.IOException;

import java.io.InputStream;

import org.apache.commons.io.IOUtils;

import net.sf.json.JSON;

import net.sf.json.xml.XMLSerializer;

public class Test {

public static void ConvertXMLtoJSON() {

InputStream is = ConvertXMLtoJSON.class.getResourceAsStream("sample.xml");

String xml;

try {

xml = IOUtils.toString(is);

System.out.println(xml);

XMLSerializer xmlSerializer = new XMLSerializer();

JSON json = xmlSerializer.read(xml);

System.out.println(json.toString(1));

} catch (IOException e) {

e.printStackTrace();

}

}

public static void main(String[] args) {

ConvertXMLtoJSON();

}

}

Java代码



/**

* 将xml字符串转换为JSON对象

* @param xmlFile xml字符串

* @return JSON对象

*/

public JSON getJSONFromXml(String xmlString) {

XMLSerializer xmlSerializer = new XMLSerializer();

JSON json = xmlSerializer.read(xmlString);

return json;

}

Java代码



/**

* 将xmlDocument转换为JSON对象

* @param xmlDocument XML Document

* @return JSON对象

*/

public JSON getJSONFromXml(Document xmlDocument) {

String xmlString = xmlDocument.toString();

return getJSONFromXml(xmlString);

}

Java代码



/**

* 将xml字符串转换为JSON字符串

* @param xmlString

* @return JSON字符串

*/

}

Java代码



/**

* 将xmlDocument转换为JSON字符串

* @param xmlDocument XML Document

* @return JSON字符串

*/

public String getXMLtoJSONString(Document xmlDocument) {

return getJSONStringFromXml(xmlDocument.toString());

}

Java代码



/**

* 读取XML文件准换为JSON字符串

* @param xmlFile XML文件

* @return JSON字符串

*/

xml = IOUtils.toString(is);

XMLSerializer xmlSerializer = new XMLSerializer();

json = xmlSerializer.read(xml);

} catch (IOException e) {

e.printStackTrace();

}

return json.toString();

}

Java代码



/**

* 将Java对象转换为JSON格式的字符串

*

* @param javaObj

* POJO,例如日志的model

* @return JSON格式的String字符串

*/

public static String getJsonStringFromJavaPOJO(Object javaObj) {

return JSONObject.fromObject(javaObj).toString(1);

}

Java代码



/**

* 将Map准换为JSON字符串

* @param map

* @return JSON字符串

*/

public static String getJsonStringFromMap(Map<?, ?> map) {

JSONObject object = JSONObject.fromObject(map);

return object.toString();
