How to send list of Long to rest controller Spring Boot

Question

I need to send list of Long objects from Angular to Rest controller in Spring boot :

@PostMapping("/accept-friends")
    public ResponseEntity<Void> acceptFriendRequests(@RequestBody List<Long> friendRequestsIds)

Is this possible ?

Create a new bean and add a list field to that bean and map that bean — Sumit Kumar, Sep 20 '18 at 08:07

Yes this is possible and will work fine.

@PostMapping("/accept-friends")
public ResponseEntity<?> acceptFriendRequests(@RequestBody List<Long> friendRequestsIds) {
  return new ResponseEntity<>(HttpStatus.OK)
}

Here you have code in Angular 6:

getData(friendRequestsIds: number[]) {
    return this.http.post<Question>('/accept-friends', friendRequestsIds);
}

You can use it like this:

@PostMapping("/listData")
public ResponseEntity<Object> listData(@RequestBody List<?> completeList) {
  return new ResponseEntity<Object>(HttpStatus.OK)
}

As I know, you can't keep the ResponseEntity<void>

I hope this will help.
