springboot获取近周的日期和对应星期几的源码

可以使用Java 8的新日期时间API来获取近周的日期和对应星期几。下面是一个示例代码：

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.ArrayList;
import java.util.List;

public class WeekDates {

    public static void main(String[] args) {
        List<String> datesAndWeekdays = getDatesAndWeekdaysOfCurrentWeek();
        for (String dateAndWeekday : datesAndWeekdays) {
            System.out.println(dateAndWeekday);
        }
    }

    public static List<String> getDatesAndWeekdaysOfCurrentWeek() {
        List<String> datesAndWeekdays = new ArrayList<>();
        LocalDate today = LocalDate.now();
        LocalDate startOfWeek = today.with(DayOfWeek.MONDAY);
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd E");
        for (int i = 0; i < 7; i++) {
            LocalDate date = startOfWeek.plusDays(i);
            String dateAndWeekday = date.format(formatter);
            datesAndWeekdays.add(dateAndWeekday);
        }
        return datesAndWeekdays;
    }
}

该代码会输出当前周的日期和对应星期几，例如：

2021-10-04 Mon
