Receive the HTTP status after a request with Spring MVC

Solution 1
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";
Solution 2
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.
