如何為 Azure 托管服務（無端口）指定 elasticsearch spring 引導配置

Question

我為 ElasticSearch 創建了一個 Azure 托管服務。 現在我想用我的 Spring Boot Elastic Application 訪問它。

注意：我用占位符 MyCustomAzureURLwithoutPort.com 隱藏了真正的 URL。 實際上，它類似於https://myclustername.es.REGION.azure.elastic-cloud.com

我的彈性配置是：

@Configuration
@EnableElasticsearchRepositories(basePackages = "org.elastic.repositories")
@ComponentScan(basePackages = { "org.elastic" })
public class ElasticsearchClientConfig extends AbstractElasticsearchConfiguration {

    @Override
    @Bean
    public RestHighLevelClient elasticsearchClient() {


        final ClientConfiguration clientConfiguration = 
                ClientConfiguration
                .builder()
                .connectedTo("https://MyCustomAzureURLwithoutPort.com")
                .withBasicAuth(user, pw)
                .build();

        return RestClients
                .create(clientConfiguration)
                .rest();
    }

但我不斷收到這樣的錯誤：

Disconnected from the target VM, address: '127.0.0.1:52567', transport: 'socket'

I also tried the URL with Port 443 ( https://myclustername.es.REGION.azure.elastic-cloud.com:443 ), that's what the Stacktrace is copied from, but this didn't worked either.

有人有想法嗎？ 需要 BasicAuth 並在沒有端口的情況下連接到此 URL。

謝謝！

彈性雲使用9243和443 。 因此，請嘗試使用9243 。

您可以在這里找到原因： 為什么 Elastic Cloud 提供專用端口（9243）而不是僅使用默認端口（443）？
