Receive the HTTP status after a request with Spring MVC

http-headers, java, spring-mvc

Solution

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";

Problem

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 ``` @RequestMapping(method = RequestMethod.POST) public String Login(@ModelAttribute("Attribute") Login login, Model model,HttpServletRequest request) { // 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); // Send the request as POST try { ResponseEntity<Login> result = restTemplate.exchange("http://www.../user/login/", HttpMethod.POST, entity, Login.class); } catch (Exception e) { } //here i want to check the received status if(status=="OK"){ return "login" } else return "redirect:/home"; } ```
