Groovy Regex：在Switch语句中捕获组

给出以下Groovy代码切换语句：

def vehicleSelection = "Car Selected: Toyota"

switch (vehicleSelection) {
   case ~/Car Selected: (.*)/:

      println "The car model selected is "  + ??[0][1] 
}

在没有定义新的(def)变量的情况下，是否可以提取单词“Toyota”？

解决方法

可以使用由Groovy添加到Matcher的lastMatcher方法：

import java.util.regex.Matcher

def vehicleSelection = 'Car Selected: Toyota'

switch( vehicleSelection ) {
   case ~/Car Selected: (.*)/: 
     println "The car model selected is ${Matcher.lastMatcher[0][1]}"
}
