Scala | String从身份证号中 解析出基本信息

案例：

• (1) 省份：42 湖北 ， 43 湖南 ， 11 北京
• (2) 市区 乡镇 4209
• (3) 出生年份：1986
• (4) 出生日期：0228
• (5) 顺序码：00
• (6) 倒数第二位 5 ，(奇数男、偶数女）
• (7) 最后一位：校验码，验证这个身份证号是不是瞎编的

分解代码：

读取性别

def getGender(idCard:String): String = {
  val gender = idCard.substring(16,17).toInt
  if(gender %2 == 0)
    "女"
  else
    "男"
}

读取生日

def getBirthday(idCard:String): String = {
  val year = idCard.substring(6,10)
  val month = idCard.substring(10,12)
  val day = idCard.substring(12,14)
  year+"-"+month+"-"+day
}

读取籍贯

def getProvince(idCard: String): String = {
  val procode = idCard.substring(0,2)
  // 14 --> 山西省
  val provinceMap = Map(
    // 直辖市
    "11" -> "北京市",
    "12" -> "天津市",
    "31" -> "上海市",
    "50" -> "重庆市",

    // 省份
    "13" -> "河北省",
    "14" -> "山西省",
    "15" -> "内蒙古自治区",
    "21" -> "辽宁省",
    "22" -> "吉林省",
    "23" -> "黑龙江省",
    "32" -> "江苏省",
    "33" -> "浙江省",
    "34" -> "安徽省",
    "35" -> "福建省",
    "36" -> "江西省",
    "37" -> "山东省",
    "41" -> "河南省",
    "42" -> "湖北省",
    "43" -> "湖南省",
    "44" -> "广东省",
    "45" -> "广西壮族自治区",
    "46" -> "海南省",
    "51" -> "四川省",
    "52" -> "贵州省",
    "53" -> "云南省",
    "54" -> "西藏自治区",
    "61" -> "陕西省",
    "62" -> "甘肃省",
    "63" -> "青海省",
    "64" -> "宁夏回族自治区",
    "65" -> "新疆维吾尔自治区",

    // 特别行政区
    "71" -> "台湾省",
    "81" -> "香港特别行政区",
    "82" -> "澳门特别行政区"
  )
  provinceMap.getOrElse(procode, "未知")
}

读取年龄

def getAge(idCard: String): Int = {
  val year = idCard.substring(6, 10).toInt
  // 获取当前年份
  val currentYear = LocalDate.now().getYear
  currentYear - year
}

读取星座

def getZodiac(idCard:String): String = {
  val month = idCard.substring(10,12).toInt
  val day = idCard.substring(12,14).toInt
  val zodiacs = Array("摩羯座", "水瓶座", "双鱼座", "白羊座", "金牛座", "双子座", "巨蟹座", "狮子座", "处女座", "天秤座", "天蝎座", "射手座")
  val boundaries = Array(1222, 120, 219, 321, 420, 521, 622, 723, 823, 923, 1023, 1122)
  val date = month * 100 + day
  val index = boundaries.search(date).insertionPoint
  zodiacs(index)
}
