Response for preflight has invalid HTTP status code 403 + angular 2 + Java Spring boot

Question

I am making an API GET call to the server with following headers in angular 2. My angular 2 code is as follows:

let headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Authorization', `${this.publisherAccessTokenVar}`);

let options = new RequestOptions({ headers: headers });

return this.http.get( 'https://blahblah', options)
            .retryWhen((error) => error.delay(this.appConfig.serviceCallRetryDelay))
            .timeout(this.appConfig.serviceCallRetryTimeOut)
            .map((response: Response) => response.json());

MY spring boot CORS code is as follows:

HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", ((HttpServletRequest) req).getHeader("Origin"));
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods", "POST,PUT, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Access-Control-Request-Method,Access-Control-Request-Headers,Content-Type, Accept, X-Requested-With, remember-me, Authorization, X-XSRF-TOKEN");
        chain.doFilter(req, res);

I am getting following error:

OPTIONS http://blah-blah.com/abcd/logout 403 (Forbidden)
XMLHttpRequest cannot load http://blah-blah.com/abcd/logout. Response for preflight has invalid HTTP status code 403

How to solve this??

Answer 1

you have to add @CrossOrigin before your controller declaration .
