Getting 403 forbidden for below code, though "https://jsonplaceholder.typicode.com/posts/1" works in postman
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
RestTemplate rt = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
String url = "https://jsonplaceholder.typicode.com/posts/1";
ResponseEntity<String> res = rt.exchange(url, HttpMethod.GET, entity, String.class);
System.out.println(res);
}
}
Error:

If someone can suggest, what i need to add in my code
Try to add a "User-Agent" header to your request. You can either try to set a custom user agent value or use some value that identifies a Browser like "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36"
