The default exception in spring, if thrown (and not handled by ControllerAdvice) follows the exception format as
{
"timestamp": "2020-06-14T05:46:37.538+00:00",
"status": 401,
"error": "Unauthorized",
"message": "Unauthorized",
"path": "/path_requested"
}
To change this default exception body to return your own custom fields, you just have to override the BasicErrorController(provided by the framework) and its error method.
- How to override
@RestController
@RequestMapping({"${server.error.path:${error.path:/error}}"})
@Slf4j
public class BasicErrorControllerOverride extends AbstractErrorController {
public BasicErrorControllerOverride(ErrorAttributes errorAttributes) {
super(errorAttributes);
}
@RequestMapping
public ResponseEntity<Map<String, Object>> error(HttpServletRequest request) {
HttpStatus status = this.getStatus(request);
Map<String, Object> errorCustomAttribute = new HashMap<>();
errorCustomAttribute.put("custome_message", "error");
errorCustomAttribute.put("custom_status_field", status.name());
return new ResponseEntity(errorCustomAttribute, status);
}
@Override
public String getErrorPath() {
return "/error";
}
}
- How the error will now look like:
{
"custome_message": "UNAUTHORIZED",
"custom_status_field": "error"
}
