In this article, we will discuss about “How to create a Spring Boot + Spring Data + Elasticsearch Example”.

Tools used in this article :

  1. Spring Boot 1.5.1.RELEASE
  2. Spring Boot Starter Data Elasticsearch 1.5.1.RELEASE
  3. Spring Data Elasticsearch 2.10.RELEASE
  4. Elasticsearch 2.4.4
  5. Maven
  6. Java 8
  7. Note
    SpringBoot 1.5.1.RELEASE and Spring Data Elasticsearch 2.10.RELEASE supports only ElasticSearch 2.4.0. They don’t support the latest version of ElasticSearch 5.x version. Read this – Spring Data Elasticsearch Spring Boot version matrix
  8. Related – Elasticsearch Basics

2. Project Dependency

Declares a spring-boot-starter-data-elasticsearch for Spring Data ElasticSearch application.
