🏆 Starter example for using Elasticsearch repository with Springboot

Requirement

Head: Elasticsearch Chrome Extension

Note

Please download ElasticSearch of 2.4.x if you are using Spring Boot 1.5.x. If you don't use correct versions then you should get following error:

Install and run Elastic Server 6.8.3

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.8.3

Open browser and hit localhost:9300 and you should see below response
