• JSON-B serialization support for RESTEasy
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-resteasy-jsonb"
• Validate object properties (field, getter) and method parameters for your beans (REST, CDI, JPA)
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-hibernate-validator"
• Call REST Services
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-rest-client"

Start Playing with Quarkus by running:

./mvnw compile quarkus:dev

Run tests using:

./mvnw test

Before building the container image run:

./mvnw package -Pnative

Then, build the image with:

docker build -f src/main/docker/Dockerfile.native -t quarkus/quarkus-getting-started .

Then run the container using:

docker run -i --rm -p 8080:8080 quarkus/quarkus-getting-started

quarkus-data

Additional extensions:

• JSON-B serialization support for RESTEasy
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-resteasy-jsonb"
• Define your persistent model with Hibernate ORM and JPA
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-hibernate-orm"
• Simplify your persistence code for Hibernate ORM via the active record or the repository pattern
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-hibernate-orm-panache"
• Connect to the MariaDB database via JDBC
  • ./mvnw quarkus:add-extension -Dextensions="io.quarkus:quarkus-jdbc-mariadb"

Use a docker image for the MariaDB instance:

docker run -ti --rm -e MYSQL_ROOT_PASSWORD=developer -e MYSQL_USER=developer -e MYSQL_PASSWORD=developer -e MYSQL_DATABASE=developer -p 3306:3306 mariadb:10.4.4
