这些东西经常用，贴出来以便查询。
1、struts中的常量类（时间<1>）
package struts.news;

import java.text.*;
import java.util.*;
public final class Constants {
	// Session keys
    public static final String DATASOURCE_KEY = "mysqlDB";
    public static final String LOGIN_USERNAME_KEY = "username";
    public static final String NEWS_LIST_KEY = "newslist";
    public static final String NEWS_DETAIL_KEY = "newsDetail";
               //system date
    public static final String getDate(){
		Calendar cal = Calendar.getInstance();
		java.text.SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String cdate = sdf.format(cal.getTime());
        
		//System.out.println("times is :"+cdate);
		return cdate; 
	}
}
2、时间<2>
java.util.Date date=new java.util.Date(); 
int yyyy=1900+date.getYear(); 
int mm=date.getMonth()+1; 
int dd=date.getDate(); 
int hh=date.getHours(); 
int mi=date.getMinutes(); 
int ss=date.getSeconds(); 
String theDate= yyyy+"-"+mm+"-"+dd; 
String theDates= yyyy+"-"+mm+"-"+dd+" "+hh+":"+mi+":"+ss;
