Java Data Elasticsearch 客户端将端口 9200 附加到 url

Question

Spring Data Elasticsearch version：

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-elasticsearch</artifactId>
<version>3.2.6.RELEASE</version>
</dependency>

我不明白为什么我的 Elasticsearch 高级客户端总是强制端口9200即使我指定了端口443。

以下是我定义RestHighLevelClient的方式：

@Slf4j
@Configuration
public class ElasticsearchConfiguration {
@Value("${elasticsearch.host:127.0.0.1}")
private String elasticsearchHost;
@Value("${elasticsearch.port:9200}")
private String elasticsearchPort;
@Bean(destroyMethod = "close")
public RestHighLevelClient client() throws IOException {
log.info("Creating High level rest client for Elasticsearch with host: " + elasticsearchHost);
ClientConfiguration configuration = ClientConfiguration.builder()
.connectedTo(elasticsearchHost + ":" + elasticsearchPort)
.usingSsl()
.build();
return RestClients.create(configuration).rest();
}
@Bean
public ElasticsearchRestTemplate getElasticsearchTemplate() throws IOException {
return new ElasticsearchRestTemplate(client());
}
}

以及我如何使用模板：

private ElasticsearchRestTemplate elasticsearchTemplate;
@Autowired
public ElasticsearchServiceImpl(@Qualifier("getElasticsearchTemplate") ElasticsearchRestTemplate elasticsearchRestTemplate) {
this.elasticsearchTemplate = elasticsearchRestTemplate;
}
@PostConstruct
public void init() throws IOException {
create indexes...
}

我已经验证了主机和端口都在属性文件中设置：

--elasticsearch.host=https://vpc-example-ryphgjfwji3zonliyhhd3nu.eu-west-2.es.amazonaws.com
--elasticsearch.port=443

在我收到的堆栈跟踪错误中：Caused by: java.io.IOException: https://vpc-example-ryphgjfwji3zonliyhhd3nu.eu-west-2.es.amazonaws.com:443:9200，它似乎将9200附加到 url 的末尾。为什么会这样？

我已经验证了通过 curl 成功建立的连接。

编辑：添加了另一个堆栈跟踪

Answer 1

您可以尝试创建如下所示的 resthighleval 客户端：

RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
RestClient.builder(new HttpHost(configuration.getElasticsearchConfig().getHost(),
configuration.getElasticsearchConfig().getPort(),
"https")));

并使用以下配置，请注意我将端口配置留空：

--

elasticsearch.host=https：//vpc-example-ryphgjfwji3zonliyhhd3nu.eu-west-2.es.amazonaws.com --elasticsearch.port=

我过去曾创建过与 AWS ES 和托管在 AWS 中的 ES 的连接，如果您遇到代码问题，请告诉我，很乐意为您提供进一步的帮助。

Answer 2

指定主机时不要指定协议 (https(。在您的情况下，它将是：

--elasticsearch.host=vpc-example-ryphgjfwji3zonliyhhd3nu.eu-west-2.es.amazonaws.com
--elasticsearch.port=443
