Answer 1

You can manually set headers as follows.

imports:

import org.springframework.http.HttpHeaders;

code:

public ResponseEntity> doSomething() {
   ...
HttpHeaders respHeaders = new HttpHeaders();
respHeaders.add("Pragma", "no-cache");
respHeaders.add("Cache-Control","no-cache,no-store,must-revalidate");
return new ResponseEntity>(respHeaders, HttpStatus.OK);
}
