如何在Spring Boot中的Elasticsearch中创建TransportClient期间配置代理主机和代理端口

Question

我正在使用ElasticSearch TransportClient。我想在TransportClient配置时添加代理信息： 请在我的TransportClient配置下面提交

Settings settings = Settings.settingsBuilder().put("cluster.name", cluster).put("node.name", node).build();
        TransportClient transportClient = TransportClient.builder().settings(settings).build();

transportClient.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(hostname.trim()), port));

如何配置代理主机和端口？
