获取根据当前时间 得到本周内的每一天的开始时间与结束时间的日期 最后的时间为59:59:59 输出的时间格式为2020-09-09 00:10:10java

可以使用Java中的Calendar类来获取本周内每一天的开始时间和结束时间，然后将这些时间格式化输出。

下面是一个示例代码：

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class Main {
    public static void main(String[] args) {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        // 获取当前时间
        Calendar calendar = Calendar.getInstance();
        Date now = calendar.getTime();

        // 获取本周的第一天和最后一天
        calendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
        Date startOfWeek = calendar.getTime();
        calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
        Date endOfWeek = calendar.getTime();

        // 输出每一天的开始时间和结束时间
        for (int i = Calendar.MONDAY; i <= Calendar.SUNDAY; i++) {
            calendar.set(Calendar.DAY_OF_WEEK, i);
            Date day = calendar.getTime();
            String startTime = sdf.format(day) + " 00:00:00";
            String endTime = sdf.format(day) + " 23:59:59";
            System.out.println("Day: " + sdf.format(day));
            System.out.println("Start time: " + startTime);
            System.out.println("End time: " + endTime);
        }
    }
}

输出结果为：
