Receive the HTTP status after a request with Spring MVC

Question

i\'m sending data to a server and i want to receive the HTTP response status in order to check this status and provide the appropriate view

   @RequestMappin         


        

Answer 1

What's wrong with:

HttpStatus status = result.getStatusCode();
if(status == HttpStatus.OK)

See: ResponseEntity JavaDoc.

BTW you should not compare strings using == operator like here:

status=="OK"

Instead use the following idiom:

"OK".equals(status)

Also method names in Java tend to start with lower case.

Answer 2

The ResponseEntity object contains the HTTP status code.

// Prepare acceptable media type
ArrayList<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
acceptableMediaTypes.add(MediaType.APPLICATION_XML);

// Prepare header
HttpHeaders headers = new HttpHeaders();
headers.setAccept(acceptableMediaTypes);

HttpEntity<Login> entity = new HttpEntity<Login>(login, headers);
// Create status variable outside of try-catch block
HttpStatus statusCode = null;

// Send the request as POST
try {
  ResponseEntity<Login> result = restTemplate.exchange("http://www.../user/login/", 
  HttpMethod.POST, entity, Login.class);
  // Retrieve status code from ResponseEntity
  statusCode = result.getStatusCode();
} catch (Exception e) {
}
// Check if status code is OK
if (statusCode == HttpStatus.OK) {
  return "login"
}
else          
  return "redirect:/home";
