Is there a way to have spring framework 4 annotation @Value convert or cast a int[] array to Integer[] array? I know that it is possible to convert an int to Integer. But I am not sure about the array

I am getting the int[] from a configuration file

tcp.port=20001,20002,20003

and using spring's @Value to read those values as a Integer[]

@Value("${tcp.port}")
private Integer[] tcpPorts;

I cannot use int[] because of a generic method in the code. Is there a way to convert/cast int[] to Integer[] with spring? Thank you!

I'm confused by your snippet. Are you just demonstrating the `int` to `Integer` conversion? Where are you getting the `int[]` from? – Sotirios Delimanolis Jul 13 '17 at 15:22
Sorry about that.. this is just to show that there is a way to convert int to Integer. I am trying to find out if there is a way to convert int[] to Integer[] using spring's @Value – CMPE Jul 13 '17 at 15:24
Show us your `int[]`. Where does it come from? – Sotirios Delimanolis Jul 13 '17 at 15:24
it is not duplicate because I am trying to convert the integer array @SotiriosDelimanolis – CMPE Jul 13 '17 at 15:48
Yeah, the accepted answer in the duplicate works for `Integer[]` the same as it does for `List`. – Sotirios Delimanolis Jul 13 '17 at 15:50
And you could always use `toArray` from the `List` to get an `Integer[]`. – Sotirios Delimanolis Jul 13 '17 at 15:51
