Connect with Elasticsearch 8 with https enabled

[hafza7869]

Can you please guide how to connect with elasticsearch with https enabled. As with elasticsearch starting with version 8 autoconfigurations automatically enable the security. After lots of research on internet and documentation I am unable to find any soluiton about how to connect spring boot - spring data elasticsearch with elasticsearch version 8.7 with https enabled. Any guidance will be appreciated.
Regards,

The Elasticsearch documentation shows 2 different ways to create a SSLContext that can be used to access the cluster (this is nothing that can be done from Spring Data Elasticsearch):

1. https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/connecting.html#_verifying_https_with_a_certificate_fingerprint
2. https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/connecting.html#_verifying_https_with_a_ca_certificate

This SSLContext can then be passed to the Spring Data Elasticsearch configuration - there's an overload method usingSsl(SSLContext).

Well thanks my savior, after trying to resolve just this issue for two three days, I am able to connect elasticsearch with spring project

I'm having a look if or how best to add this to the configuration class, maybe something like usingSsl(String certificateFingerprint) which then will be used when building an Elasticsearch 8 client.
