How to express int array[6] in YAML

[1, 2, 3, 4, 5, 6]

or

- 1
- 2
- 3
- 4
- 5
- 6

You should simply use a list:

[1, 2, 3, 4, 5, 6]

It throws IllegalArgumentException in my spring application, when I use [1, 2, 3, 4, 5, 6] in application.yaml. However it works when i use 1,2,3,4,5,6

my annotation code is

@Value("${app.groupIds}")
private int[] groupIds;
