如何通过 Java High Level Rest Client 实现安全弹性搜索

我是弹性搜索新手。通过将我的 Spring boot 应用程序与 Elastic 搜索集成Java High Level Rest Client.

我已经配置了 JHLRC bean，如下所示，它工作正常：

@Bean(destroyMethod = "close")
public RestHighLevelClient client() {
  RestHighLevelClient client = new RestHighLevelClient(
      RestClient.builder(new HttpHost("localhost", 9200, "http")));
  return client;
}

开始探索 Elasticsearch 的安全性，设置证书和密码后，我通过提供以下属性启用了安全性：

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12

我可以使用创建的用户名和密码登录 kibana，但在通过 JHLRC 访问任何 Elastic search API 时收到 401 Unauthorized。

有人可以帮助我在配置时需要进行哪些进一步的更改吗Java High Level Rest Client想要实现安全的 Elastic 搜索？

在 JHLRC 中进行以下更改后，它起作用了：

@Bean(destroyMethod = "close")
  public RestHighLevelClient client() {

    final BasicCredentialsProvider basicCredentialsProvider = new BasicCredentialsProvider();
    basicCredentialsProvider
        .setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("elastic", "password_generated_by_elastic_search"));

    RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
        RestClient.builder(new HttpHost("localhost", 9200, "http"))
            .setHttpClientConfigCallback(new HttpClientConfigCallback() {
              @Override
              public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                httpClientBuilder.disableAuthCaching();
                return httpClientBuilder.setDefaultCredentialsProvider(basicCredentialsProvider);
              }
            })

    );

    return restHighLevelClient;
  }
