在Spring WebFlux webclient中设置超时-Java 学习之路

我正在使用Spring Webflux WebClient从我的Spring启动应用程序进行REST调用 . 并且每次在30秒内超时 .

这是我尝试在Spring webfulx的WebClient中设置套接字超时的一些代码 .

- ReactorClientHttpConnector connector = new ReactorClientHttpConnector(options -> options
           .option(ChannelOption.SO_TIMEOUT, 600000).option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 600000));
 - ReactorClientHttpConnector connector = new ReactorClientHttpConnector(
           options -> options.afterChannelInit(chan -> {
                chan.pipeline().addLast(new ReadTimeoutHandler(600000));
            }));
 - ReactorClientHttpConnector connector1 = new ReactorClientHttpConnector(options -> options
            .option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 600000).afterNettyContextInit(ctx -> {
                ctx.addHandlerLast(new ReadTimeoutHandler(600000, TimeUnit.MILLISECONDS));
            }));

并尝试使用“clientConnector”方法在“WebClient”中添加上面的连接器设置 .

并尝试设置超时如下：

webClient.get().uri(builder -> builder.path("/result/{name}/sets")
                    .queryParam("q", "kind:RECORDS")
                    .queryParam("offset", offset)
                    .queryParam("limit", RECORD_COUNT_LIMIT)
                    .build(name))
            .header(HttpHeaders.AUTHORIZATION, accessToken)
            .exchange().<b><i>timeout(Duration.ofMillis(600000))</i></b>
            .flatMap(response -> handleResponse(response, name, offset));

上述选项均不适合我 .

我正在使用org.springframework.boot：spring-boot-gradle-plugin：2.0.0.M7，它们具有org.springframework的依赖性：spring-webflux：5.0.2.RELEASE .

请在这里建议，如果我在这里做错了，请告诉我 .

我已经尝试过复制这个问题而且不能 . 使用reactor-netty 0.7.5.RELEASE .

我不确定你在说什么超时 .

可以使用 ChannelOption.CONNECT_TIMEOUT_MILLIS 配置连接超时 . 我在"connecting"日志消息和实际错误之间得到10秒：

WebClient webClient = WebClient.builder()
    .clientConnector(new ReactorClientHttpConnector(options -> options
        .option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 10000)))
    .build();

webClient.get().uri("http://10.0.0.1/resource").exchange()
    .doOnSubscribe(subscription -> logger.info("connecting"))
    .then()
    .doOnError(err -> logger.severe(err.getMessage()))
    .block();

如果你're talking about read/write timeouts, then you can look at Netty' s ReadTimeoutHandler 和 WriteTimeoutHandler .

一个完整的示例可能如下所示：

ReactorClientHttpConnector connector = new ReactorClientHttpConnector(options ->
        options.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 10)
                .onChannelInit(channel -> {
                        channel.pipeline().addLast(new ReadTimeoutHandler(10))
                                .addLast(new WriteTimeoutHandler(10));
                return true;
        }).build());

从Reactor Netty 0.8和Spring Framework 5.1开始，配置现在看起来像这样：

TcpClient tcpClient = TcpClient.create()
                 .option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 1000)
                 .doOnConnected(connection ->
                         connection.addHandlerLast(new ReadTimeoutHandler(10))
                                   .addHandlerLast(new WriteTimeoutHandler(10)));
WebClient webClient = WebClient.builder()
    .clientConnector(new ReactorClientHttpConnector(HttpClient.from(tcpClient)))
    .build();

也许在 application.properties 中添加以下内容将提供有关HTTP级别发生的更多信息：

logging.level.reactor.ipc.netty.channel.ContextHandler=debug
logging.level.reactor.ipc.netty.http.client.HttpClient=debug
