Overview

In this project, We will show the usage of ElasticsearchRepository and ElasticsearchTemplates. This project uses Spring-data-elasticsearch and that is compatible with ElasticSearch 2.4.4 only. Don't use ElasticSearch 5.x and above with spring-data-elasticsearch as it is not updated yet with latest version. If you want to use latest ElasticSearch 5.x then you need to directly use Spring with Transport or node client apis. See dependencies details on this link - https://github.com/spring-projects/spring-data-elasticsearch/wiki/Spring-Data-Elasticsearch---Spring-Boot---version-matrix

Step 1 Download the code from github

git clone https://github.com/RajeshBhojwani/spring-boot-elasticsearch.git

Step 2 Build the project

mvn clean install

Step 3 Launch the application

java -jar target\elasticsearch-0.0.1-SNAPSHOT.jar

Step 4 Use Curl or Postman to test the REST apis created.
