解决方案

    @Bean
    public RestClientBuilder elasticsearchRestClientBuilder() {
        CreatorProperties.Es es = creatorProperties.getEs();
        HttpHost[] hosts = es.getUris().stream().map(HttpHost::create).toArray(HttpHost[]::new);
        RestClientBuilder builder = RestClient.builder(hosts);
        PropertyMapper map = PropertyMapper.get();
        map.from(es::getUsername).whenHasText().to((username) -> {
            CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
            Credentials credentials = new UsernamePasswordCredentials(es.getUsername(), es.getPassword());
            credentialsProvider.setCredentials(AuthScope.ANY, credentials);
            RequestConfig requestConfig = RequestConfig
                    .custom()
                    .setConnectTimeout(5000)
                    .setSocketTimeout(60000)
                    .setConnectionRequestTimeout(60000)
                    .build();
            builder.setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder
                    .setDefaultCredentialsProvider(credentialsProvider)
                    .setDefaultRequestConfig(requestConfig)
            );
            builder.setRequestConfigCallback(rcc -> rcc
                    .setConnectTimeout(5000)
                    .setSocketTimeout(60000)
                    .setConnectionRequestTimeout(60000)
            );
            // 实际作用代码
            builder.setMaxRetryTimeoutMillis(60000);
        });
        return builder;
    }

解决思路

1. 必应搜索，得到 RequestConfig 设置，乍一看，应该没问题了。然并卵，还是报错。
2. 掏出异常日志，定位源码。
   点两下就能找到这里，这个 timeout 是 RestClient 的属性，找下这个对象的这个属性设值就行。
