WebFlux响应式编程，通过redis验证 appkey的问题，急求

[wzwdev1980]

如果redis连接异常，会进行ex处理，但redis正常时，却不进行处理，直接进入到chain.filter(exchange)中的，怎么办

@Resource
private AppKeyProvider appKeyProvider;

public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
    try {
        String app_key =exchange.getRequest().getQueryParams().getFirst("app_key"));         
        //app_key verify
        Flux.just(app_key).flatMap(key -> appKeyProvider.getAppKey(key)).subscribe(
                appKey -> {                       
                    if (appKey == null) {
                        //app_key is not valid
                        throw new AppException(ErrorCode.ILLEGAL_APP_KEY);
                    }else{
                            //do... jump to next filter
                    }
                },
                ex -> {
                    throw new AppException(ErrorCode.SERVICE_BASIC_ERROR, ex);
                }
        );
    } catch (AppException ex) {            
        exchange.getResponse().setStatusCode(HttpStatus.BAD_REQUEST);
        exchange.getResponse().getHeaders().setContentType(MediaType.APPLICATION_JSON);
        String  result = RestHelper.build(ex, exchange).toString();                
        return exchange.getResponse().writeWith(Mono.just(exchange.getResponse().bufferFactory().wrap(result.getBytes(Charsets.UTF_8))));
    }
    return chain.filter(exchange);
}
