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

You can find the tutorial about this example at this link: Getting started with Spring Data Elasticsearch

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

• Get the 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

Since this project uses Spring Boot 3.1, all you need to do is to run the application:

$ ./mvnw spring-boot:run

Spring Boot automatically detects the docker-compose file and starts the Elasticsearch container.

The older version of this project uses Spring Boot 3.0 which does not have Spring Boot Docker Compose integration.

To run an older version of the application, 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 cluster name elasticsearch.

Then you can run the application like below:

$ ./mvnw spring-boot:run

If your Elasticsearch URI is not localhost is different simply override the following environment variable:

• ES_URI

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

The integration tests are written relying on Testcontainers to spin up Elasticsearch on the spot and run tests against it. To know more about container testing read this tutorial: Integration test with Testcontainers in Java

To run the integration test (using Testcontainers) just run the below command:

$ mvn clean verify

Make sure you have your docker running.
