在Grails2.4.3中将List（long）转换为List（String）（Groovy）

Question

Post call gives data in the form of List<Long> and now I have to convert it into List<String> , so I used this approach for it:

deleteAvailablity.startDate.each {
   startDateList.add(it.toString())
}
deleteAvailablity.startDate = startDateList

Is there any better approach than this?

Answer 1

You can use collect :

def listOfLongs = [0L, 1L, 2L]
def listOfStrings = listOfLongs.collect { it.toString() }

assert listOfStrings == ["0", "1", "2"]

Answer 2

Use the Spread Operator

This simple construct should do the job:

assert [1l, 2l, 3l]*.toString() == ['1', '2', '3']
