I´m having some issues when returning some errors from a rest WebService.
Making a request with the header {"Accept":"application/octet-stream"}
(the service returns a document ResponseEntity<InputStreamResource> if all the process goes well).
When all the process goes well the document is downloaded fine, but when an error is occurred and the code jumps to the @ControllerAdvice and tries to return a JSON error. Here comes the problem, when trying to return the JSON springs crashes:
org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation
Here is a example of some code:
Controller
@RequestMapping(value = "/test", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_OCTET_STREAM_VALUE })
public ResponseEntity<CustomError> test() throws Exception {
throw new Exception();
}
ControllerAdvice
@ControllerAdvice
public class ExceptionHandlerAdvice {
private static final Logger logger = LogManager.getLogger(ExceptionHandlerAdvice.class);
@ExceptionHandler({Exception.class,Throwable.class})
@ResponseBody
public ResponseEntity<CustomError> handleUnhandledException(Exception exception) {
CustomError error = new CustomError(exception.getMessage());
return new ResponseEntity<CustomError>(error, HttpStatus.INTERNAL_SERVER_ERROR);
}
}
CustomError:
public class CustomError {
private String errorDescription;
public CustomError(String errorDescription) {
super();
this.errorDescription = errorDescription;
}
public String getErrorDescription() {
return errorDescription;
}
public void setErrorDescription(String errorDescription) {
this.errorDescription = errorDescription;
}
}
I´ve also tried returning new headers on @controllerAdvice
@ExceptionHandler({Exception.class,Throwable.class})
@ResponseBody
public ResponseEntity<CustomError> handleUnhandledException(Exception exception) {
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
CustomError error = new CustomError(exception.getMessage());
return new ResponseEntity<CustomError>(error,headers, HttpStatus.INTERNAL_SERVER_ERROR);
}
Any idea how can I make this work or ignore Accept header on response? It´s possible?
Thanks in advance
