定义一个字符串日期;

String dataStr="2022-06-01";

public static java.sql.Timestamp parseTimestamp(String dateStr) {return parseTimestamp(dateStr, "yyyy/MM/dd HH:mm:ss");
}

public static java.sql.Timestamp parseTimestamp(String dateStr,String format) {java.util.Date date = parseDate(dateStr, format);if (date != null) {long t = date.getTime();return new java.sql.Timestamp(t);} else {return null;}
}

public static java.util.Date parseDate(String dateStr, String format) {java.util.Date date = null;try {java.text.DateFormat df = new java.text.SimpleDateFormat(format);String dt = dateStr.replaceAll("-", "/");if ((!dt.equals(""))) {dt +=format.substring(dt.length()).replaceAll("[YyMmDdHhSs]", "0");}date = (java.util.Date) df.parse(dt);} catch (Exception e) {e.printStackTrace();}return date;
}
