Groovy SpringBoot Elasticsearch

This sample project demonstrates how to build and deploy a Groovy Spring Boot application to access Elasticsearch.

Goal

Build a very simple web application with Spring Boot and Groovy to demonstrate how to access domain-specific data (for the propose of this sample: songs) from Elasticsearch.

Software Requirements

Elasticsearch Server

• Download and setup Elasticsearch server.

Rest Client

• You can use any rest client but i suggest HTTPie Command line HTTP client.

Gradle

To compile and start the application you require a Java Development Kit (JDK8) as well as Gradle.

Try it out

• Start Elasticsearch.

First you need to populate some Songs in Elasticsearch. Let's do it by command line:

http PUT localhost:9200/music/songs/1 id=1 name=Frequency year=1992 artist="Alter 8" 

http PUT localhost:9200/music/songs/2 id=2 name="Charly (Original Mix)" year=1991 artist="The Prodigy"

http PUT localhost:9200/music/songs/3 id=3 name="Jericho" year=1992 artist="The Prodigy"

http PUT localhost:9200/music/songs/4 id=4 name="LFO" year=1992 artist="LFO"

Start Application

gradle bootRun

NOTE: If you want to open the sources with your favorite IDE, you might want to generate project files for Eclipse or IntelliJ IDEA with:

gradle eclipse
gradle idea

Or you can just open the source with Sublime Text Editor.

Interact with the REST endpoints

Retrieve all Songs

http localhost:8080/sample/songs 

TODO

• Create a complete CRUD endpoints
