Cross origin error in spring boot does not recognize CrossOrigin() annotation

I have Angular in apache2 for frontend and we are using spring boot, in spring boot, I have added @CrossOrigin(origins = “https://frontend.com”) annotation on a controller, and it keeps preventing me from communicating,

`@RestController
@CrossOrigin(origins = “https://frontend.com”)
public class Department {

@Autowired
DepartmentService departmentService;

@PostMapping(“/input”)
public ResponseEntity<Message> createDepartment(@Valid @RequestBody DepartmentoDto dto) {
return ResponseEntity.ok(departmentoService.save(dto));
}`


This is the error

Request from another origin blocked: the policy of the same origin prevents reading the remote resource at https://backend/input (reason: missing CORS header 'Access-Control-Allow-Origin'). Status code: 403

Object { headers: {...}, status: 0, statusText: Unknown Error, url: https://backend/input, ok: false, name: “HttpErrorResponse”, message: 'Http failure response for https://backend/iput 0 Unknown Error', error: error }


This worked when both were in HTTP, but after switching to HTTPS.

Attempted to test it by allowing all headers, but it did not work:

@CrossOrigin(origins = “https://frontend.com”,allowedHeaders = “*”)
