结合使用Velocity和Java，我试图从'中拉出单个字段。 分隔字符串

Question

I have my velocity directive set as #set ($stringList = $string.split("."))

I have tried the following in my syntax but can't get it to work

$stringList.get(0)
$stringList[0]
$stringList.[0]
${stringList}.get(0)

Answer 1

change

#set ($stringList = $string.split("."))

to

#set ($stringList = $string.split("\\."))

and access it like

$stringList[0]
