Java中获取当前时间

Calendar calendar = Calendar.getInstance();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String createTime=formatter.format(calendar.getTime());

Date date = formatter.parse(createTime);//parse点下构造方法，date就是服务器当前时间

//public dxhfController() throws ParseException {
//}
