    public static RestHighLevelClient RestClient() {
        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost(IP, HTTP_PORT, "http")
                    ).setHttpClientConfigCallback(httpClientBuilder ->
                    httpClientBuilder.setDefaultCredentialsProvider(init()))
                );
        return client;
    }
     
    private static CredentialsProvider init() {
        CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(SecurityUser, SecurityPassword));
        return credentialsProvider;
      }
}

注意回调方法setHttpClientConfigCallback内不要添加

httpClientBuilder.disableAuthCaching()

方法。
