I am creating a GetEndpoint exposed like below
@GetMapping
public void someMethod(@RequestParam(value = "selectedColor", required = false,
defaultValue = "WHITE") Color seletedColor) {
....
}
I need to convert all method parameters to a class object like below. Please let me know how to set default value defaultValue = “WHITE” at field level in below class
@GetMapping
public void someMethod(RequestParameter request) {
....
}
public Class RequestParameter {
// How to set default value if parameter is null
private Color seletedColor;
}
Answer
I would suggest using a getter to have this logic. For example:
public class RequestParameter {
...
public Color getSelectedColor() {
return Optional.ofNullabe(selectedColor).orElse(Color.WHITE);
}
}
