Utility类：

package com.tidyinfo.utils;

import java.util.Calendar;

public class Utility {
  
    //生成形如:\2006\08\18的路径
    private String path;

    //生成形如: 20060818125012的唯一id号
    private String id;

    //生成形如：/2006/08/18的路径
    private String url;

    private String hour;

    private String year;

    private String month;

    private String day;

    private String minate;

    private String second;

    /** Creates a new instance of Utility */
    public Utility() {
        this.year =new Integer(Calendar.getInstance().get(Calendar.YEAR)).toString();
        this.month = parseToString(Calendar.getInstance().get(Calendar.MONTH)+1);

        this.hour = parseToString(Calendar.getInstance().get(Calendar.HOUR_OF_DAY));
        this.minate = parseToString(Calendar.getInstance().get(Calendar.MINUTE));
        this.second = parseToString(Calendar.getInstance().get(Calendar.SECOND));
        this.setId();
        this.setPath();
        this.setUrl();
    }

    protected String parseToString(int i){
        return i<10?("0"+i):new Integer(i).toString();
    }

    public String getId(){
        return this.id;
    }

    public String getPath(){

    }

    protected void setPath(){

                this.day ;
    }

    protected void setUrl(){
