LocalDateTime、LocalDate、Date 转为 String

上篇博客中，介绍了 LocalDateTime、LocalDate 及 Date 的相互转换，另外的场景就是需要把 LocalDateTime、LocalDate 或者是 Date与 String 字符串进行转换。

LocalDateTime、LocalDate、Date 转String

//Date转String
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String dateString = sdf.format(date);
//LocalDateTime转String
LocalDateTime localDateTime = LocalDateTime.now();
DateTimeFormatter dtf1 = DateTimeFormatter.ofPattern("yyyy-MM-dd hh:mm:ss");
String localDateTimeString = dtf1.format(localDateTime);
//LocalDate转String
LocalDate localDate = LocalDate.now();
DateTimeFormatter dtf2 = DateTimeFormatter.ofPattern("yyyy-MM-dd");
String localDateString = dtf2.format(localDate);
String 转 Date、LocalDateTime、LocalDate
//String转Date
String dateString = "2020-10-27 14:53:00";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = sdf.parse(dateString);
//String转LocalDateTime
String localDateTimeString = "2020-10-27 18:15:00";
DateTimeFormatter dtf1 = ofPattern("yyyy-MM-dd hh:mm:ss");
LocalDateTime localDateTime = LocalDateTime.parse(localDateTimeString, dtf1);
//String转LocalDate
String localDateString = "2020-10-27";
DateTimeFormatter dtf2 = ofPattern("yyyy-MM-dd");
LocalDate localDate = LocalDate.parse(localDateString, dtf2);
