string类和LocalDateTime的转换

//1.具有转换功能的对象
DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
//2.要转换的对象    
LocalDateTime time = LocalDateTime.now();

//3.发动功能
String localTime = df.format(time);
System.out.println("LocalDateTime转成String类型的时间："+localTime);

//3.LocalDate发动，将字符串转换成  df格式的LocalDateTime对象，的功能
LocalDateTime LocalTime = LocalDateTime.parse(strLocalTime,df)
System.out.println("String类型的时间转成LocalDateTime："+LocalTime);

DateTimeFormatter struct = DateTimeFormatter.ofPattern("yyyy-MM-dd")
LocalDate localDate = LocalDate.now();
String format = struct.format(localDate)
System.out.println("LocalDate转成String类型的时间："+format)
LocalDate parse = LocalDate.parse(format
System.out.println("String类型的时间转成LocalDateTime："+parse);

LocalDateTime now = LocalDateTime.now();
final DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd w hh:mm:ss");
final String format = now.format(dateTimeFormatter);
System.out.println(format);
final LocalDateTime parse = LocalDateTime.parse(format, dateTimeFormatter);
