LocalDateTime转String

package;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class Test {
          
   


    public static void main(String[] args) {
          
   

        LocalDateTime now = LocalDateTime.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        String timeStr = formatter.format(now);
        System.out.println("timeStr = " + timeStr);

    }

}

输出结果：timeStr = 2022-08-15 17:09:08

String转LocalDateTime

package;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class Test {
          
   


    public static void main(String[] args) {
          
   

        String timeStr = "2022-08-15 17:09:08";

        LocalDateTime now = LocalDateTime.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

        LocalDate date = LocalDate.parse(timeStr, formatter);
        LocalDateTime time = LocalDateTime.parse(timeStr, formatter);

        System.out.println("date = " + date);
        System.out.println("time = " + time);

    }

}
