Spring Cache Abstraction with Couchbase

Firstly, this artical is not a tutorial about Spring Cache and Couchbase Server. The intention of that is to show how to configure our Spring Boot application for using Couchbase Server as a cache storage.

Now, let’s get started. As you guess, we need run a Couchbase Server. So we will start a single node cluster Couchbase Server by using Docker.

docker run -d --name couchbase-local -p 8091-8096:8091-8096 -p 11210-11211:11210-11211 couchbase

Then check http://localhost:8091. You will see setup screen.

Setup a new Cluster with password Pass123*.

Now we need a bucket with name book-bucket.

Finally, we are done with Couchbase installation. For more detail about Couchbase installation part, you can visit here.

It is time to build the Spring Boot application from start.spring.io. Here the dependencies

start.spring.io

Next step is to set properties and make configurations. Create application.yml and CacheConfig.java files.

application.yml

CacheConfig.java

So we will implement a Book (must be implement Serializable) model and API to serve resource.

Finally we have one more annotation to make application to enable caching. Let’s add @EnableCaching.

Now we can start testing. Open terminal and run the commands.

curl --request GET http://localhost:8080/book
curl --request GET http://localhost:8080/book
curl --request GET http://localhost:8080/book/1
curl --request GET http://localhost:8080/book/1
curl --request GET http://localhost:8080/book/2
curl --request GET http://localhost:8080/book/2

Here is the application logs.
