java - Java数据Elasticsearch客户端将端口9200附加到url中

Spring Data Elasticsearch版本。

<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将端口设置为 9200 即使我指定的端口是 443.

我是这样定义的 RestHighLevelClient:

@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());
    }
}

以及我是如何使用模板的。

private ElasticsearchRestTemplate elasticsearchTemplate;

@Autowired
public ElasticsearchServiceImpl(@Qualifier("getElasticsearchTemplate") ElasticsearchRestTemplate elasticsearchRestTemplate) {
    this.elasticsearchTemplate = elasticsearchRestTemplate;
}

@PostConstruct
public void init() throws IOException {
    create indexes...
}

我已经确认了主机和端口都在属性文件中被设置了。

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

在我收到的stacktrace错误信息中: Caused by: java.io.IOException: https://vpc-example-ryphgjfwji3zonliyhhd3nu.eu-west-2.es.amazonaws.com:443:9200它似乎在附加 9200 到url的末尾。为什么会出现这种情况？

我已经验证了通过curl成功连接。

编辑：添加了另一个堆栈跟踪

un 09 21:44:44 ip-10xxxx95.pre.xxx-prototype.xxx.uk bash[19738]: 2020-06-09 21:44:44.023 ERROR 19738 --- [           main] c.g.c.s.impl.ElasticsearchServiceImpl    : https://vpc-example-ryphgjfwji3zonliyhhd3nu.eu-west-2.es.amazonaws.com: Name or service not known

你可以尝试创建resthighleval客户端，像下面。

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

并使用下面的配置，注意我把端口配置留空。

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

我已经创建了一个连接到AWS ES和ES托管在AWS过去，让我知道，如果你面临的代码问题，将很乐意进一步帮助。
