JAVA的把JSON写入Properties

import net.sf.json.JSONObject;
import java.io.*;
import java.util.Iterator;
import java.util.Properties;
public class JsonToPropUtils {


    public static void jsonToProp(String jsonStr,String Path) {
        JSONObject jsonObj=JSONObject.fromObject(jsonStr);
        
        File file = new File(Path);
        try {
            OutputStream os = new FileOutputStream(Path);
            InputStream is = new FileInputStream(file);
            Properties prop=new Properties();
             prop.load(is);
             Iterator it =jsonObj.keys();
             while(it.hasNext()){
                 String key=(String) it.next();
                 String value=(String)jsonObj.get(key);
                 prop.setProperty(key, value);
             }
             prop.store(os, null);
             is.close();
             os.close();  
                     
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block

            e.printStackTrace();
        }        
    }
    
    //主方法
    public static void main(String[] args) {
        String jsonStr="{‘key‘:‘1‘,‘name‘:‘liuli‘}";
        jsonToProp(jsonStr,"Pro.properties");
