val ids = "1 ,2,  3"
val result = ids.split(',').map(_.trim.toLong)

works also with spaces between the numbers, and performs marginally better because doesn't implicitly use a regexp for the splitting part.

val ids = "1,2,3"
val result = ids.split(",").map(_.toLong)

result: Array[Long] = Array(1, 2, 3)
