rest - Spring MVC - RestTemplate launch exception when http 404 happens

Question

I have a rest service which send an 404 error when the resources is not found. Here the source of my controller and the exception which send Http 404.

@Controller
@RequestMapping("/site")
public class SiteController
{

    @Autowired
    private IStoreManager storeManager;

    @RequestMapping(value = "/stores/{pkStore}", method = RequestMethod.GET, produces = "application/json")
    @ResponseBody
    public StoreDto getStoreByPk(@PathVariable long pkStore) {       
        Store s = storeManager.getStore(pkStore);
        if (null == s) {
            throw new ResourceNotFoundException("no store with pkStore : " + pkStore);
        }
        return StoreDto.entityToDto(s);       

    }
}
 
@ResponseStatus(value = HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException
{       
    private static final long serialVersionUID = -6252766749487342137L;    
    public ResourceNotFoundException(String message) {
        super(message);
    }    
}

When i try to call it with RestTemplate with this code :

ResponseEntity<StoreDto> r = restTemplate.getForEntity(url, StoreDto.class, m);
 System.out.println(r.getStatusCode());
 System.out.println(r.getBody());

I receive this exception :

org.springframework.web.client.RestTemplate handleResponseError
ATTENTION: GET request for "http://........./stores/99" resulted in 404 (Introuvable); invoking error handler
org.springframework.web.client.HttpClientErrorException: 404 Introuvable

I was thinking I can explore my responseEntity Object and do some things with the statusCode. But exception is launch and my app go down.

Is there a specific configuration for restTemplate to not send exception but populate my ResponseEntity.

Answer 1

As far as I'm aware, you can't get an actual ResponseEntity, but the status code and body (if any) can be obtained from the exception:

try {
    ResponseEntity<StoreDto> r = restTemplate.getForEntity(url, StoreDto.class, m);
}
catch (final HttpClientErrorException e) {
    System.out.println(e.getStatusCode());
    System.out.println(e.getResponseBodyAsString());
}
