如何在Java中禁用Elasticsearch RestClient v6.7.0的SSL验证

RestClientBuilder builder = RestClient.builder(
    new HttpHost("localhost", 9200, "https"))
    .setHttpClientConfigCallback(new HttpClientConfigCallback() {
        @Override
        public HttpAsyncClientBuilder customizeHttpClient(
                HttpAsyncClientBuilder httpClientBuilder) {
            return httpClientBuilder.setSSLContext(
                SSLContexts.createSystemDefault())
                .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE);
        }
    });

RestHighLevelClient client = new RestHighLevelClient(builder);
