An example to demonstrate how Spring Data ElasticSearch works

# Spring Data ElasticSearch Example
2+
3+
## Introduction
4+
5+
This example demonstrates how to use Spring Data ElasticSearch to do simple CRUD operation.
6+
7+
You can find the tutorial about this example at the below link:
8+
9+
[https://blog.madadipouya.com](https://blog.madadipouya.com)
10+
11+
For this example, a Book controller created that allows to do the following operations with ElasticSearch:
12+
13+
- Get list of all books
14+
- Create a book
15+
- Update a book by Id
16+
- Delete a book by Id
17+
- Search for a book by ISBN
18+
19+
20+
## How to run
21+
22+
The first thing to do is to start ElasticSearch. For that you can use the `docker-compose` file in this project
23+
and run it like this:
24+
25+
```bash
26+
$ docker-compose -f docker-compose up -d
27+
```
28+
29+
It brings ElasticSearch up on a single node cluster with the cluser name `elasticsearch`.
30+
31+
Then you can run the application like below:
32+
33+
```bash
34+
$ ./mvnw spring-boot:run
35+
```
36+
37+
If your ElasticSearch URI is not `localhost` and/or the cluster name is different simply override one or both of the following environment variable:
38+
39+
- `ES_URI`
40+
- `ES_CLUSTER_NAME`
41+
42+
Once everything is up and running open the browser and go to [http://localhost:8080](http://localhost:8080). You should see Swagger to interact with.
