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

Question

Spring 数据 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 Highlevel 客户端总是强制端口为 9200，即使我指定了端口 443。

我是这样定义 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...
}

我已验证主机和端口都已在属性文件中设置：

--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，似乎是将 9200 附加到 url 的末尾。为什么会这样？

我已确认通过 curl 连接成功。

编辑：添加了另一个堆栈跟踪

Answer 1

你能尝试像下面这样创建 resthighleval 客户端吗:

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

并使用以下配置，注意我将端口配置留空：

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

我过去创建了一个到 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，我们很乐意进一步提供帮助。

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
