Building all subprojects

Build all subprojects by calling the quarkusBuildSubprojects task.

./gradlew quarkusBuildSubprojects

Quarkus Intro

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:

./gradlew quarkusDev

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:

./gradlew build

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

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

./gradlew build -Dquarkus.package.type=uber-jar

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

Creating a native executable

You can create a native executable using:

./gradlew build -Dquarkus.package.type=native

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

./gradlew build -Dquarkus.package.type=native -Dquarkus.native.container-build=true

You can then execute your native executable with: ./build/quarkus-hibernate-reactive-panache-1.0.0-SNAPSHOT-runner

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

quarkus-examples's Issues

Error in Ripe method in Hibernate Panache Reactive

The problem is when updating several records at once, on the ripe methos.

Improve Hibernate Reactive Panache Example

• The update query does not persist in the DB although the statement is inside a transaction that should made the commit automatically.
• Add unique and non-unique indexes to entities

Replace keycloak client functional with the trikorasolns/keycloak-quarkus-client

Replace the keycloak REST client with the trikorasolns/keycloak-quarkus-client library.

REQUIRES: the library is published to Maven Central.

Implement security example for keyclock

Handling exceptions in Panache

Use wrapper as :
@ReactiveTransactional
private Function<Calendar, Uni<? extends Calendar>> createCalendarFunction() {
return calendar -> {
try {
return repoCalendar.persistAndFlush(calendar);
} catch (PersistenceException ex) {
LOGGER.info("PersistenceException: {}", ex);
if (ex.getMessage().contains("Duplicate entry")) {
throw new DuplicateObjectException("Calendar", calendar.calendarKey.toString());
} else {
throw new com.trikorasolutions.keycloak.client.exception.TrikoraGenericException(ex.getMessage());
}
}
};
}

In order to handle exceptions from the hibernate

Fetch role information from Keycloak
