You can add headers to the ResponseEntity builder. I think it is cleaner this way.

import org.springframework.http.HttpHeaders;
import org.springframework.http.ResponseEntity;

// ...

@GetMapping("/my/endpoint")
public ResponseEntity myEndpointMethod() {

    HttpHeaders headers = new HttpHeaders();
    headers.add(HttpHeaders.CONTENT_TYPE, "application/json; charset=UTF-8");

    return ResponseEntity.ok()
            .headers(headers)
            .body(data);
}
