页面
<input type="text" name="user.1-name" />
<input type="text" name="user.2-name" />

后台:
def users = params.remove('user')
Map split = users?.inject([:]) { map, param ->

List list = param.key.split('-')
if (list.size() != 2) { // only allow for 1 '-' in a param
return map
}
String firstKey = list.first()
String lastKey = list.last()
if (!map.get(firstKey)) {
map."$firstKey" = [:] // init map for this key
}
map."$firstKey"."$lastKey" = param.value
return map
}

for(String key : map.keySet()){
println "key :"+key+" value:"+map.get(key)

def user = new User(map.get(key))
println user.name
}
