xml & json 转换工具

书上看的,实验了一下,结果还不错.收藏下来.

package com;
import java.util.*;

import net.sf.json.JSONObject;

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class ExtHelper {
	public static String getXmlFormList(long recordTotal,List beanList){
		Total total = new Total(); //保存记录总数
		total.setResults(recordTotal); //设置记录总数到 total对象
		List results = new ArrayList(); //创建临时的 List 对象 results
		results.add(total); // 添加对象
		results.addAll(beanList); // 追加对象
		XStream sm = new XStream(new DomDriver()); //创建Xstream对象
		for(int i=0;i<results.size();i++){
			Class c = results.get(i).getClass();
			String b = c.getName();
			String[] temp = b.split("\\.");
			sm.alias(temp[temp.length-1],c);
		}
		String xml = "<?xml version='1.0' encoding='UTF-8'?>"+sm.toXML(results);
		return xml;
	}
	
	public static String getJsonFromList(long recordTotal,List beanList){
		TotalJson total = new TotalJson();
		total.setResults(recordTotal);
		total.setItems(beanList);
		JSONObject jsonArray = JSONObject.fromObject(total);
		return jsonArray.toString();
	}
}

package com;

import java.util.ArrayList;
import java.util.List;
import com.ExtHelper;

public class testjson {
	public static void main(String[] args){
		PhoneNumber homePhone = new PhoneNumber("宅电","123456");
		PhoneNumber officePhone = new PhoneNumber("办公电话","456789");
		List phoneList = new ArrayList();
		phoneList.add(homePhone);
		phoneList.add(officePhone);
		String json = ExtHelper.getJsonFromList(phoneList.size(), phoneList);
		System.out.println(json);
	}
}

package com;

import java.util.ArrayList;
import java.util.List;

public class JsonListTest {
	public static void main(String[] args){
		PhoneNumber homePhone = new PhoneNumber("宅电","123456");
		PhoneNumber officePhone = new PhoneNumber("办公电话","456789");
		List phoneList  = new ArrayList();
		phoneList.add(homePhone);
		phoneList.add(officePhone);
		
	}
}
