Question

我在Mkyong网站上关注本教程 https://www.mkyong.com/spring-boot/spring-boot-spring-data-elasticsearch-example/

它使用spring-boot-starter-data-elasticsearch库连接到elasticSearch

我使用以下详细信息尝试连接到亚马逊上的弹性搜索实例

elasticsearch.host=<search address in amazon elastic search console>
elasticsearch.port=9200
elasticsearch.clustername=<accountId:clusterName>`

但是我一直收到以下错误

我需要做些什么才能连接到亚马逊上的弹性搜索实例？

由于达明

Answer 1

AWS Elasticsearch不支持TCP连接，仅支持HTTP连接。这解释了为什么CURL命令有效，但是你的java连接不起作用。

TCP transport
The service supports HTTP on port 80, but does not support TCP transport.

http://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/aes-supported-resources.html

Answer 2

AWS Elasticsearch仅适用于使用Rest API的端口80。 elasticsearch的默认传输API不适用于Hosted AWS elasticsearch。

我必须自定义Jest client以添加额外的挂钩以对每个请求进行签名。

您可能需要参阅Stack Overflow上的this帖子，了解有关如何签署HTTP请求的更多详细信息。

Answer 3

使用主机：托管的AWS Elasticsearch的IP地址或托管的AWS es和PORT的路径：80

例如：

10.100.1.1:80或xyz.abc.com:80

Spring Boot弹性搜索并且无法连接
