Spring Data Elasticsearch Example

Introduction

This example demonstrates how to use Spring Data Elasticsearch to do simple CRUD operation.

You can find the tutorial about this example at the below link:

https://geekyhacker.com/2019/05/01/getting-started-with-spring-data-elasticsearch/

For this example, a Book controller created that allows to do the following operations with Elasticsearch:

• Get list of all books
• Create a book
• Update a book by Id
• Delete a book by Id
• Search for a book by ISBN
• Fuzzy search for books by author and title

How to run

The first thing to do is to start Elasticsearch. For that you can use the docker-compose file in this project and run it like this:

$ docker-compose -f docker-compose up -d

It brings Elasticsearch up on a single node cluster with the cluser name elasticsearch.

Then you can run the application like below:

$ ./mvnw spring-boot:run

If your Elasticsearch URI is not localhost and/or the cluster name is different simply override one or both of the following environment variable:

• ES_URI
• ES_CLUSTER_NAME

Once everything is up and running open the browser and go to http://localhost:8080. You should see Swagger to interact with.

Run testcontainers tests

The integration tests written relying on testcontainers to spin up Elasticsearch on the spot to run tests against.

To know more about container read this tutorial: https://geekyhacker.com/2019/05/08/integration-test-with-testcontainers-in-java/

To run them just execute below command:

$ mvn clean verify

Make sure you have your docker running.
