在java中，使用RestHighLevelClient 怎么连接 search-guard

public static RestClientBuilder getRestClientBuilder(int port, String user, String pwd, String... ips) {

        HttpHost[] httpHosts = new HttpHost[ips.length];

        for (int i = 0; i < ips.length; i++) {

            String ip = ips[i];

            httpHosts[i] = new HttpHost(ip, port, "http");

        }

        String esAuth = "";

        if (StrUtil.isNotBlank(user) && StrUtil.isNotBlank(pwd)) {

            esAuth = "Basic " + Base64.encode(user + ":" + pwd);

        }

        Header[] defaultHeaders = new Header[]{new BasicHeader("Authorization", esAuth)};

        RestClientBuilder clientBuilder = RestClient.builder(httpHosts);

        clientBuilder.setDefaultHeaders(defaultHeaders);

        clientBuilder.setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder

                .setConnectTimeout(5000)

                .setSocketTimeout(150000))

                .setMaxRetryTimeoutMillis(150000);

        return clientBuilder;

    }
