你从数据库取出的rs.getTimestamp("AccessRight")值为空，就抛出：java.lang.NullPointerException

可以用getString

也可用：
public Date Str2Date(String dt) throws DateFormatException{
Date temp = null;
String ps = dt;
if(ps.equals("")){
return null;
}
if(ps.length() == 19){
String part1 = ps.substring(0,2);
String part2 = ps.substring(2,4);
String part3 = ps.substring(4,8);
ps = part1 + "-" + part2 + "-" + part3;
//System.out.println("the ps is::-->>" + ps);
}
try{
temp = df.parse(ps);
}
catch(ParseException e){
throw new DateFormatException("'" + dt + "' is not a valid date match format 'dd/mm/yyyy'" );
}
if(!ps.equals(df.format(temp))){
temp = null;
throw new DateFormatException("'" + dt + "' is not valid date match format 'dd/mm/yyyy'" );
}
return temp;
}

String strUpLoadTm = tmUpLoad.toString();
out.println(strUpLoadTm);
