在Elasticsearch高级客户端中为JAVA添加身份验证

您可以将用户名和密码指定给Java Low Level REST Client，然后将Low Level REST
Client传递给

RestHighLevelClient

final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY,        new UsernamePasswordCredentials("user", "password"));RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200))        .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() { @Override public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {     return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider); }        });RestHighLevelClient client = new RestHighLevelClient(builder);
