• WebApplication is the starting point of the program.
• The homepage (index.html) must be in resources/public
• Put all thymeleaf templates in resources/templates folder

Dependencies

• JDK 1.8 or upper
• tomcat 9
• springboot 2.3
• elasticsearch 7.10
• kibana 7.10 (optional if you want show a dashboard on homepage)

Run

I use IntelliJ IDEA and run the WebApplication file without much hassle. The homepage will be available at http://localhost:8081.

• make sure you have a running Elasticsearch server at port 9300. You can change the confing in Esconfig file.
• If you'd like to show a dashboard/chart etc. with Kibana, also have Kibana up and running. Have a look at this discussion to see how to do it. You must have created the dashboard/charts beforehand. In the screenshot, I have already added a few articles and created a dashboard.

If you had any problems, perhaps follow the install guide on spring boot tutorial.

Maintenance

I made this project around September 2018 when I was learning about working with Elasticsearch and Spring Boot. I used this tutorial as a starting point for Spring Boot. For Elasticsearch part, I've used Bealdung's tutorial. Since the Spring Data Elasticsearch's API has changed a lot since the first time I made this project, I've tried to update the deprecated parts and the project works fine as of December 2020. For now, I don't intend to maintain this repository for future updates of the APIs (but I might change my mind since I like Elasticsearch!).
