Configure Elasticsearch rest high level client with Basic credential provider

问题

This question was asked in the follow-up question to my this SO answer of how to secure JHLRC in this comment, where I explained how to send Basic Credential in Elasticsearch JHLRC request but it was not at the client level and was at the request level.

I feel configure at the client level, would avoid repeating the same code again in cases, where you are dealing with only a few users it would be helpful to configure the credentials in the client itself.

You can follow the below steps as mentioned in this official link.

Create CredentialsProvider using the BasicCredentialsProvider.

final CredentialsProvider credentialsProvider =
                new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY,
                new UsernamePasswordCredentials("elastic", "elastic"));

Now use the CredentialsProvider while building the rest client(JHLRC).

RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
                RestClient.builder(new HttpHost(scannerConfiguration.getElasticsearchConfig().getHost(),
                        scannerConfiguration.getElasticsearchConfig().getPort(),
                        "http")).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                    @Override
                    public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                        return httpClientBuilder
                                .setDefaultCredentialsProvider(credentialsProvider);
                    }
                }));
