Quarkus Redis Sample

Primary LanguageHTML

quarkus-redis-sample

This project uses Quarkus, the Supersonic Subatomic Java Framework.

If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Dnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Dnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/quarkus-redis-sample-1.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.

Testing the Redis Client

Testing in dev mode is fairly simple when using Dev Service. Just build and start Quarkus in dev mode:

mvn clean install quarkus:dev

To begin with, we can start storing one key in Redis Storage:

curl -X POST -H "Content-Type: application/json" -d '{"key": "sampleKey", "value": 42}' http://localhost:8080/redis

Then, check the list of keys with the GET command:

curl -X GET http://localhost:8080/redisc["sampleKey"]

Next, in our application we have not implemented a method to decrement a key. For this purpose, let’s execute the Raw Redis DECR command:

curl -X POST http://localhost:8080/redisc/DECR/sampleKey

Verify the value of the key after decrementing it:

curl -GET http://localhost:8080/redis/sampleKeyey
{"key":"sampleKey","value":41}
