SSL / HTTPS Connection with Low Level Rest API?

Elastic Stack Elasticsearch
1

I am using low level rest API to access Elastic Search in AWS (AWS Service). Aws provides the HTTPS url.

    @Bean
    public RestClient restClient() throws Exception {
        RestClient restClient = RestClient.builder(new HttpHost(esHost, esPort))
                .setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(5000)
                        .setSocketTimeout(60000))
                .setMaxRetryTimeoutMillis(60000)
                .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                    @Override
                    public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                        HttpAsyncClientBuilder httpAsyncClientBuilder = null;
                        try {
                            httpAsyncClientBuilder = httpClientBuilder.setSSLContext(SSLContext.getDefault());
                        } catch (NoSuchAlgorithmException e) {
                            e.printStackTrace();
                        }
                        return httpAsyncClientBuilder;
                    }
                })
                .build();
        return restClient;
    }

I am not able to get RestClient over SSL connection.

Following are the error messages:

Please suggest me what is needed to get a RestClient over SSL connection.
Thanks

Try passing "https" as a third argument to the constructor.

@TimV Thank you so much. It really worked. Now I don't have to use JEST or other api's.
