*/
public static String getAddDateToString(Date date,int addTime,String unit){
DateTime dateTime = new DateTime(date);
DateTime dateTime1=null;
if(unit.equals("天")){
dateTime1= dateTime.plusDays(addTime); 
}else if(unit.equals("小时")){
dateTime1 = dateTime.plusHours(addTime); 
}else if(unit.equals("分钟")){
dateTime1 = dateTime.plusMinutes(addTime); 
}else if(unit.equals("day")){
dateTime1= dateTime.plusDays(addTime); 
}else if(unit.equals("hour")){
dateTime1 = dateTime.plusHours(addTime); 
}else if(unit.equals("minute")){
dateTime1 = dateTime.plusMinutes(addTime); 
}
return dateTime1.toString("yyyy-MM-dd HH:mm:ss:SSS");
