        credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(userName, passWord));  //es账号密码
        esClient = new RestHighLevelClient(
            RestClient.builder(
                new HttpHost(host, port)
            ).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                    httpClientBuilder.disableAuthCaching();
                    return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
                }
