--重点---自测可以Spring Boot 中关于自定义异常处理CustomErrorController

@RestController
public class CustomErrorController extends BasicErrorController {
    @Autowired
    public CustomErrorController(ErrorAttributes errorAttributes,
                           ServerProperties serverProperties,
                           List<ErrorViewResolver> errorViewResolvers) {
        super(errorAttributes, serverProperties.getError(), errorViewResolvers);
    }

    @RequestMapping
    @Override
    public ResponseEntity<Map<String, Object>> error(HttpServletRequest request) {
        Map<String, Object> body = getErrorAttributes(request, this.isIncludeStackTrace(request, MediaType.ALL));
        Boolean errorFlags = (Boolean) body.getOrDefault("errorFlags", false);
        if (errorFlags) {
            Integer statusI = (Integer) body.getOrDefault("status",500);
            return new ResponseEntity(body, HttpStatus.valueOf(statusI));
        }
        return super.error(request);
    }
}


@Component
public class CustomErrorAttributes extends DefaultErrorAttributes {
    @Override
    public Map<String, Object> getErrorAttributes(RequestAttributes requestAttributes, boolean includeStackTrace) {
        final Throwable error = super.getError(requestAttributes);
        if (error instanceof ForbiddenException) {
            Map<String, Object> errorAttributes = new LinkedHashMap();
            errorAttributes.put("timestamp", new Date());
            errorAttributes.put("errorFlags", true);
            errorAttributes.put("status", ForbiddenException.STATUS);
            errorAttributes.put("message", error.getMessage());
            return errorAttributes;
        } else {
            return super.getErrorAttributes(requestAttributes, includeStackTrace);
        }
    }
}
