Java Code Example with @Value​

For a requirement where you need to read values from a configuration file into a List<Integer> property, you can use the @Value annotation to achieve this.

YAML Configuration​

api:
  ids: 1,2,3

Java Code​

@Value("#{'${api.ids}'.split(',')}")
private List<Integer> ids;
warning

If you use @Value("${api.ids}") directly, it will throw an error and fail to parse. However, it will work correctly if the type is List<String>.
