Question

我正在尝试在此代码中集成验证，但是验证失败，没有任何错误（只是返回了空白页）：

@Component
@Slf4j
public class EthereumAccountController implements ClarityControllerMono {

    private final Pipeline queryPipeline;

    private final Pipeline commandPipeline;

    private final Web3jService web3;

    private final RequestHandler requestHandler;

    public EthereumAccountController(@Qualifier("queryPipelinr") Pipeline queryPipeline, @Qualifier("commandPipelinr") Pipeline commandPipeline, Web3jService web3, RequestHandler requestHandler) {
        this.queryPipeline = queryPipeline;
        this.commandPipeline = commandPipeline;
        this.web3 = web3;
        this.requestHandler = requestHandler;
    }

    public Mono<ServerResponse> createAccount(ServerRequest serverRequest) {


        return requestHandler.requireValidBody(body -> getJsonErrsResp("testtttt"), serverRequest, AccountRequestDTO.class);


    }

}

public interface ClarityControllerMono {



    default Mono<ServerResponse> getJsonSuccessResp (Object object) {
        Map<String, Object> result = new LinkedHashMap<>();
        result.put("status", "success");
        result.put("data", object);

        return ok()
                .contentType(APPLICATION_JSON)
                .body(BodyInserters.fromPublisher(Mono.just(toJSON(result)), String.class));
    }


    default Mono<ServerResponse> getJsonErrsResp (Object object) {
        Map<String, Object> result = new LinkedHashMap<>();
        result.put("status", "error");
        result.put("message", object);

        return ok()
                .contentType(APPLICATION_JSON)
                .body(BodyInserters.fromPublisher(Mono.just(toJSON(result)), String.class));
    }

    private String toJSON(Object object) {

            ObjectMapper objectMapper = new ObjectMapper();
            return Unchecked.function(objectMapper::writeValueAsString).apply(object);
        }

}

这是代码失败的地方

@Component
public class RequestHandler {

    private final Validator validator;

    public RequestHandler(Validator validator) {
        this.validator = validator;
    }

    public <BODY> Mono<ServerResponse> requireValidBody(
            Function<Mono<BODY>, Mono<ServerResponse>> block,
            ServerRequest request, Class<BODY> bodyClass) {

        return request
                .bodyToMono(bodyClass)
                .flatMap(
                        body -> validator.validate(body).isEmpty()
                                ? block.apply(Mono.just(body))
                                : ServerResponse.unprocessableEntity().build()
                );
    }
}

这是我在其中找到要实现的有趣解决方案的存储库（失败的部分代码） https://github.com/jeroenbellen/Validate-functional-endpoints-in-Spring/blob/master/src/main/java/foo/bar/springfunctionalwebvalidation/controller/RequestHandler.java

谢谢。

编辑

    public <BODY> Mono<ServerResponse> requireValidBody(
            Function<Mono<BODY>, Mono<ServerResponse>> block,
            ServerRequest request, Class<BODY> bodyClass) {
        Hooks.onOperatorDebug();
        return request
                .bodyToMono(bodyClass)
                .doOnError(Throwable::printStackTrace)
                .flatMap(
                        body -> {
                            log.info("Emptyness" +validator.validate(body).isEmpty() + "");
                           return validator.validate(body).isEmpty()
                                    ? block.apply(Mono.just(body))
                                    : ServerResponse.unprocessableEntity().build();
                        }
                ).doOnError(Throwable::printStackTrace);

doOnError不会放任何东西。
