Scala中的case match语法

val Pattern="(s.*)".r

    val v1="spark";

    val r=v1 match  {      
      case Pattern(v1)=> "begin s*"
      case "1"=> "1"
      case "2"=> "2"
      case _=> "default"
    }

    println(r) // begin s*

val v1=1

    val r=v1 match  {      
      case 1=> "1"
      case 2=> "2"
      case 3=> "3"
      case _=> "default"
    }

    println(r)// 1

val v1=3

    val r=v1 match  {     
     case v1 if 1 until 5 contains v1=> "1-5"
     case v1 if 5 until 10 contains v1=> "5-10"
     case _=> "not found"
    }

    println(r)//1-5

val v1=3

    val r=v1 match  {     
     case v1 if (v1>0 && v1<=5) => "1-5"
     case v1 if (v1>5 && v1<=10)=> "5-10"
     case _=> "not found"
    }

    println(r)
