2 | # Overview
3 | In this project, We will show the usage of ElasticsearchRepository and ElasticsearchTemplates.
4 | This project uses Spring-data-elasticsearch and that is compatible with ElasticSearch 2.4.4 only.
5 | Don't use ElasticSearch 5.x and above with spring-data-elasticsearch as it is not updated yet with latest version.
6 | If you want to use latest ElasticSearch 5.x then you need to directly use Spring with Transport or node client apis.
7 | See dependencies details on this link -
8 | https://github.com/spring-projects/spring-data-elasticsearch/wiki/Spring-Data-Elasticsearch---Spring-Boot---version-matrix
9 |
10 | ## Step 1 Download the code from github
11 | ```git clone https://github.com/RajeshBhojwani/spring-boot-elasticsearch.git ```
12 |
13 | ## Step 2 Build the project
14 | ```mvn clean install```
15 |
16 | ## Step 3 Launch the application
17 | ```java -jar target\elasticsearch-0.0.1-SNAPSHOT.jar```
18 |
19 | ## Step 4 Use Curl or Postman to test the REST apis created.
20 | UserController has api using ElasticsearchTemplate
21 | UserRepositoryController has api using ElasticsearchRepository
22 |
23 | ## APIs for ElastisearchTemplate usage
24 | 1. POST call for creating new User-
25 | http://localhost:8102/new
26 |
27 | ### JSON data
28 | ```
29 | {
30 | "name": "Sumit",
31 | "userSettings": {
32 | "gender" : "male",
33 | "occupation" : "CA",
34 | "hobby" : "chess"
35 | }
36 | }
37 | ```
38 |
39 | 2. GET call for Retrieve all Users
40 | http://localhost:8102/all
41 |
42 | 3. Add User setting entry by name
43 | http://localhost:8102/settings/Deepika/hobby/poetry
44 |
45 | For other apis, check code.
46 |
47 | ## APIs for ElasticsearchRepository usage
48 |
49 | 1. POST call for creating new User-
50 | http://localhost:8102/repo/new
51 | ### JSON Data
52 | ```
53 | {
54 | "name": "Deepika",
55 | "userSettings": {
56 | "gender" : "Female",
57 | "occupation" : "Software Engineer",
58 | "hobby" : "racing"
59 | }
60 | }
61 | ```
62 |
63 | 2. GET call for Retrieve all Users -
64 | http://localhost:8102/repo/all
65 |
66 |
67 | 3. Add User settings entry by for a userId -
68 | http://localhost:8102/repo/settings/AWdeQyaoTJbZRlQtLZfL/hobby/chess
69 |
70 | For other apis, check code.
