Lesson 4: Working With Data (Elasticsearch)

Introduction

This example shows how you can connect your microservce to Elasticsearch.

Building and running the sample

Use the following commands to build run the application:

$ mvn clean package
$ java -jar target/livelessons-data-elasticsearch-1.0.0-SNAPSHOT.jar

The example uses an embedded elasticsearch server to store data. If you want to talk to a real server you can set spring.data.elasticsearch.cluster-name and spring.data.elasticsearch.cluster-nodes properties.

Understanding the code

The familiar Car domain is used again in this example. This time Car is a elasticsearch document (signified with the Spring Data @Document annotation). The same Repository logic is used as before providing a findByMakeIgnoringCase method.

The DataElasticsearchApplication class also shows how you can use the ElasticsearchTemplate to make native elasticsearch queries. In this case we are performing a fuzzy search for manufacturers like ronda.
