bi数据报表发送周期，周报和月报获取日期时间

1.今天是周四，获取上周四-本周三的日期，格式为yyyyMMddHHmmss

String startTime = "";String endTime = "";// 获取当前日期时间（假设今天是2025-09-19周四）LocalDateTime now = LocalDateTime.now();// 计算上周四（当前周数减1，调整到周四）LocalDateTime lastThursday = now.minusWeeks(1).with(java.time.DayOfWeek.THURSDAY).withHour(0).withMinute(0).withSecond(0);;// 计算本周三（当前周数不变，调整到周三）LocalDateTime thisWednesday = now.with(java.time.DayOfWeek.WEDNESDAY).withHour(23).withMinute(59).withSecond(59);;// 定义输出格式DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");// 输出结果
//            System.out.println("上周四: " + lastThursday.format(formatter));
//            System.out.println("本周三: " + thisWednesday.format(formatter));startTime = lastThursday.format(formatter);endTime = thisWednesday.format(formatter);

2.今天是当前月的1号，获取上月1号-上月31号日期，格式为yyyyMMddHHmmss

String startTime = "";String endTime = "";// 获取当前日期（假设是2025-09-01）LocalDateTime now = LocalDateTime.now();// 计算上个月的第一天00:00:00LocalDateTime firstDayOfLastMonth = now.minusMonths(1).withDayOfMonth(1).withHour(0).withMinute(0).withSecond(0);// 计算上个月的最后一天23:59:59LocalDateTime lastDayOfLastMonth = YearMonth.from(firstDayOfLastMonth).atEndOfMonth().atTime(23, 59, 59);// 定义输出格式DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");// 输出结果
//            System.out.println("上月1号: " + firstDayOfLastMonth.format(formatter));
//            System.out.println("上月31号: " + lastDayOfLastMonth.format(formatter));startTime = firstDayOfLastMonth.format(formatter);endTime = lastDayOfLastMonth.format(formatter);
