Answer 1

You can try this

@Pattern(regexp="^[0-9]+(,[0-9]+)*$")
private static final String VALIDATION_REGEX;

(pay attention for the final modifier) or else

 @Pattern()
 private static final String VALIDATION_REGEX = "^[0-9]+(,[0-9]+)*$";

And then remove @Pattern(regexp = VALIDATION_REGEX) from your method and keep only the @Valid annotation:

public myResonseObject getMyParams(@PathVariable("id") String id, @Valid @RequestParam(value = "myparam", required = true) String myParam) {
