DateScope 时间枚举工具

import cn.sybn.bean.scope.DateScope;

// 闭区间, 支持日常常用的多种时间格式
DateScope scope = DateScope.create("20180101~2018-01-05");

// 默认打印每一天
int size = scope.size(); // size = 5
StringBuilder sb = new StringBuilder();
for (Date date : scope) {
	sb.append(DayUtil.dayToInt(date));
	sb.append("/");
}
sb.toString(); // sb = "20180101/20180102/20180103/20180104/20180105/"

// 枚举String格式的时间

}
