从另一个字符串中提取groovy中的子字符串

Question

我有一个字符串：

pRoiGroup="[com.testing.Location#533bfa78d3f9645043e4eb25]"

我想从"533bfa78d3f9645043e4eb25"获取字符串pRoiGrop。我怎么能这样做？

Answer 1

String result = pRoiGroup - "[com.testing.Location#" - "]"

Answer 2

def result= pRoiGroup.split("#")[1][0..-2]

Answer 3

或者：

def result = pRoiGroup.find( /#([a-f0-9]*)]/ ) { it[ 1 ] }

Answer 4

pRoiGroup[++pRoiGroup.indexOf(/#/)..-2] //No list involved
