5.代码奉上,只需传入时间参数
1.假设上班时间如下:
- 上班时间为:08:30:00
- 中午休息时间为:12:00:00 到13:30:00
- 下班时间:18:00:00
- 每次请假必须至少请假半天(例如:08:30到12:00算0.5天 12:00到18:00算0.5天) 以上
- 支持2019和2020年国家法定节假日,其他年份请自行添加
2.请假时间计算方式:
任选两个时间段(无论是从周末、国家节假日开始请假 到 周末、国家节假日结束请假 都支持)
2.1.去掉周六周末(但是国家调休的有些班是在周六周末 所以要做判断,如果周六或者周末 是国家规定调休的班,那么就不能去掉,否则去掉)
2.2.去掉国家法定节假日
3.请假可能存在的情况:
3.1. 请假日期和结束日期相同(同一天) 例如:2019-12-1008:30:00 - 2019-12-1012:00:00
3.2 .请假日期和结束日期相邻(相邻的两天)例如:2019-12-1008:30:00 - 2019-12-11 12:00:00
3.3.请假日期和结束日期不相邻(中间有间隔)例如:2019-12-10 08:30:00 - 2019-12-13 12:00:00
4.实现思路:
分三部分计算各自的请假时间,相加即可
第一部分:请假的当天的请假总时间(要么是半天,要么是一天)
第二部分:请假的中间的请假总时间(不包含第一部分和第三部分)
第三部分:结束的当天的请假总时间(要么是半天,要么是一天)
5.代码奉上,只需传入时间参数
/**
* @param startTime Java接受的格式:Sun Dec 08 08:30:00 GMT+08:00 2019
* 前端传的格式是 2019-12-08 08:30:00
*
* @param endTime 和startTime格式是一样的
