使用分隔符拆分字符串

我目前正在尝试拆分一个字符串 1128-2，以便我可以有两个独立的值。例如 value1:1128和 value2:2，这样我就可以分别使用每个值。我试过 split()，但没有成功。Grails 是否有一种特定的方法来处理这个问题，或者有更好的方法来处理这个问题？

最佳答案

Try:

def (value1, value2) = '1128-2'.tokenize( '-' )

How are you calling split? It works like this:

def values = '1182-2'.split('-')
assert values[0] == '1182'
assert values[1] == '2'

def (value1, value2) = '1128-2'.split('-') should work.

Can anyone please try this in Groovy Console?

def (v, z) =  '1128-2'.split('-')


assert v == '1128'
assert z == '2'

split doesn't work that way in groovy. you have to use tokenize...

See the docs:

http://groovy-lang.org/gdk.html#split()

You can also do:

Integer a = '1182-2'.split('-')[0] as Integer
Integer b = '1182-2'.split('-')[1] as Integer


//a=1182 b=2
