Netty Http 客户端 - 配置 DNSResolution 超时

Question

我在使用 WebClient 时遇到此错误。根据我的配置，这是预期的。但是如何通过netty http客户端配置dns名称解析的超时时间呢？

Caused by: io.netty.resolver.dns.DnsNameResolverTimeoutException: [/127.0.0.11:53] query via UDP timed out after 5000 milliseconds (no stack trace available)

默认情况下，DNS 查询超时为 5 秒 ( DEFAULT_QUERY_TIMEOUTHttpClient )，但如果需要，您可以自定义下划线 Netty

HttpClient httpClient = HttpClient.create()
        .resolver(spec -> spec.queryTimeout(Duration.ofSeconds(10)));

WebClient client = WebClient.builder()
        .clientConnector(new ReactorClientHttpConnector(httpClient))
        .build();
