Spring Data Redis Example with Kotlin

Introduction

This example shows how to use Spring Data with Redis to do CRUD operations. Additionally, it demonstrates using Redis as a message broker.

The code is implemented using Kotlin, but it's easy for Java developers to understand as well.

For more in-depth details, have a look at the tutorials at links below:

Endpoints

To demonstrate CRUD operations, I use Movie, Actor model and created some endpoints to do basic CRUD operations as follows:

  • Create Movie
  • Update Movie
  • Delete Movie
  • List Movies
  • Create Actor
  • Update Actor
  • Delete Actor
  • List Actors
  • Add an Actor to a Movie

How to run

The project needs Redis to run. There's a docker-compose file contains all necessary configuration to run Redis flawlessly.

To use it. Just run:

$ docker-compose -f docker-compose.yml up -d

After that the Redis should be accessible via port 6379 on localhost

Then you can run the application like below:

$ ./mvnw spring-boot:run -Dserver.port=8090

If you have a Redis running in another port or host, simply override below environment variables:

  • SPRING_REDIS_HOST
  • SPRING_REDIS_PORT

Or modify application.properties file.

To interact with the APIs, after running the project, just open http://localhost:8080/swagger-ui/index.html. You should see Swagger to interact with.
