public static void main (String[] args) { 
        String s1 = "2003-09-14"; 
        String s2 = "2003-05-24"; 
        String t1 = s1.replace('-','/'); 
        String t2 = s2.replace('-','/'); 
        try{  
            Date dt1= new Date(t1); 
            Date dt2= new Date(t2); 
            System.out.println("dt1="+dt1.getTime()); 
            System.out.println("dt2="+dt2.getTime()); 
            long l = dt1.getTime() - dt2.getTime(); 
     
            System.out.println("---------->;"+l/60/60/1000/24); 
        }catch(Exception e){ 
            System.out.println("exception"+e.toString()); 
        } 
}

import java.util.Date;

import org.apache.commons.lang.time.DurationFormatUtils;

public class Test {

	public static void main(String[] args) throws Exception {
		Date start = java.sql.Timestamp.valueOf("2009-12-05 11:30:00");
		Date end = java.sql.Timestamp.valueOf("2009-12-21 11:05:30");
		String result = DurationFormatUtils.formatPeriod(start.getTime(), end.getTime(), "dd'天");
		System.out.println(result);
	}
}

运行结果：15天
