Is it possible with GET Rest Method to pass collection of objects as URL parameters?

class Person{
  String name;
  String surname;
  ...
}

public ResponseEntity<List<PersonInfo>> getInfoAboutPersons(@RequestParam List<Person> persons)

I try to send JSON as string and parse it. I became: "Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986", because of '[', ']'.

My only solution is pass list of String (name,surname) and then split and convert to objects, what is not really elegance.

Can someone help by example?

No, you need to `POST` for that data. – Kayaman Oct 07 '19 at 12:27

Also you may consider sending the JSON string in the `@RequestBody` . – Arnaud Oct 07 '19 at 12:29

@NavinGelot Ok, but how to call it in postman? – Mateusz Nowakowski Oct 07 '19 at 12:33
I think you could [URLEncode](https://docs.oracle.com/javase/7/docs/api/java/net/URLEncoder.html) your URL String, although the correct way to do it is using `POST` instead of `GET`. – Top.Deck Oct 07 '19 at 12:38

@Jannis Those posts are about List of Strings, but I need list of object with few fields. – Mateusz Nowakowski Oct 07 '19 at 12:53
