quarkus-dbclient project

This project uses Quarkus, the Supersonic Subatomic Java Framework.

This sample project for testing hibernate-panache and rest endpoint in quarkus. The result of my experiment is exceed my expectation with average request response under 10 ms with my current hardware.

Running the application in dev mode

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

./mvnw quarkus:dev

Sample request from employees DB (examples DB from MySQL) :

curl --location --request GET 'http://localhost:8080/api/employees/10015' \
--header 'Accept: application/json' \
--data-raw ''

Response :

{
    "birthDate": "1959-08-19",
    "empNo": 10015,
    "firstName": "Guoxiang",
    "gender": "M",
    "hireDate": "1987-07-02",
    "lastName": "Nooteboom"
}

Packaging and running the application

The application can be packaged using ./mvnw package. It produces the quarkus-dbclient-1.0.0-SNAPSHOT-runner.jar file in the /target directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/lib directory.

The application is now runnable using java -jar target/quarkus-dbclient-1.0.0-SNAPSHOT-runner.jar.

Creating a native executable

You can create a native executable using: ./mvnw package -Pnative.

Or, if you don't have GraalVM installed, you can run the native executable build in a container using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your native executable with: ./target/quarkus-dbclient-1.0.0-SNAPSHOT-runner

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