Convert between DATE and String

The front-end passes the date type to the back-end, but the back-end cannot receive data

Processing method 1: convert the date to a string and send it to the background, and convert the background string to a date and then assign it

public class DateConvert {
    public static void main(String[] args) {
        Date date = null;
        String str="2018-04-24 00:00:00";
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        try {
            date=sdf.parse(str);//String 转 DATE
        } catch (ParseException e) {
            e.printStackTrace ();
        }
        System.out.println(date);
        //DATE转String
        str=sdf.format(date);
        System.out.println(str);
        }
}

result:

Tue Apr 24 00:00:00 CST 2018
2018-04-24 00:00:00
