Spring 5 webflux如何在Webclient上设置超时

我正在尝试在我的WebClient上设置超时,这是当前代码：

SslContext sslContext = SslContextBuilder.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE).build();

ClientHttpConnector httpConnector = new ReactorClientHttpConnector(opt -> {
    opt.sslContext(sslContext);
    HttpClientOptions option = HttpClientOptions.builder().build();
    opt.from(option);
});
return WebClient.builder().clientConnector(httpConnector).defaultHeader("Authorization", xxxx)
                .baseUrl(this.opusConfig.getBaseURL()).build();

我需要添加超时和汇集策略,我想的是这样的：

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
cm.setMaxTotal(this.applicationConfig.getHttpClientMaxPoolSize());
cm.setDefaultMaxPerRoute(this.applicationConfig.getHttpClientMaxPoolSize());
cm.closeIdleConnections(this.applicationConfig.getServerIdleTimeout(), TimeUnit.MILLISECONDS);

RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(this.applicationConfig.getHttpClientSocketTimeout())
        .setConnectTimeout(this.applicationConfig.getHttpClientConnectTimeout())
        .setConnectionRequestTimeout(this.applicationConfig.getHttpClientRequestTimeout()).build();

CloseableHttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(requestConfig).setConnectionManager(cm).build();

但我无法弄清楚如何在我的webclient中设置httpClient

解决方法:

WebFlux WebClient不使用Apache Commons HTTP Client.虽然您可以通过自定义ClientHttpConnector实现一个解决方案.现有的ReactorClientHttpConnector基于Netty.因此,请考虑使用Netty选项来配置客户端,例如：

ReactorClientHttpConnector connector =
            new ReactorClientHttpConnector(options ->
                    options.option(ChannelOption.SO_TIMEOUT, this.applicationConfig.getHttpClientConnectTimeout()));

要么

.onChannelInit(channel -> channel.config().setConnectTimeoutMillis(this.applicationConfig.getHttpClientConnectTimeout()))

UPDATE

我们也可以使用ReadTimeoutHandler：

.onChannelInit(channel -> 
        channel.pipeline()
           .addLast(new ReadTimeoutHandler(this.applicationConfig.getHttpClientConnectTimeout())))
