Hi everyone I'm migrating from Wildfly to Quarkus, but unable to understand how to programmatically retrieve a named datasource. Below the code used until now in Wildfly to retrieve datasourceName programmatically (datasource datasourceName already defined in application.properties along with many others)
Properties p = new Properties();
p.put(AvailableSettings.DATASOURCE, datasourceName);
p.put(AvailableSettings.JTA_PLATFORM, JBossAppServerJtaPlatform.class.getName());
p.put("current_session_context_class", "jta");
p.put(AvailableSettings.SHOW_SQL, false);
p.put(AvailableSettings.FORMAT_SQL, false);
// Adding "hibernate.classLoaders" property is critical for this to work with keycloak!!!
p.put(AvailableSettings.CLASSLOADERS, Collections.singletonList(getClass().getClassLoader()));
entityManagerFactory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME, p);
conf/quarkus.properties
quarkus.datasource.user-store.db-kind=mysql
quarkus.datasource.DATASOURCEA.db-kind=mysql
quarkus.datasource.DATASOURCEA.username=USER
quarkus.datasource.DATASOURCEA.password=PASSWORD
quarkus.datasource.DATASOURCEA.jdbc.url=jdbc:mysql://HOSTNAME/DATABASE
When running such code in Quarkus, exception is thrown
The FastbootHibernateProvider PersistenceProvider can not support runtime provided properties. Make sure you set all properties you need in the configuration resources before building the application.
given by this FastBootHibernatePersistenceProvider.java line
@SuppressWarnings("rawtypes")
private void verifyProperties(Map properties) {
if (properties != null && properties.size() != 0) {
throw new PersistenceException(
"The FastbootHibernateProvider PersistenceProvider can not support runtime provided properties. "
+ "Make sure you set all properties you need in the configuration resources before building the application.");
}
}
Meaning, no property is allowed.
Tried with
Arc.container().instance(EntityManagerFactory.class, new PersistenceUnit.PersistenceUnitLiteral(datasourceName))
but throwing
WARN [org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator] (JPA Startup Thread: user-storage-jpa) HHH000342: Could not obtain connection to query metadata: java.lang.UnsupportedOperationException: The application must supply JDBC connections

Any hint on this? Really struggling to find any useful reference to accomplish this. Can find only injection-based datasources.
thanks a lot, nicola
Have you seen the following? It is based on an example from one of the Keycloak Developers
MyUserStorageProvider(KeycloakSession session, ComponentModel model) {
this.session = session;
this.model = model;
em = session.getProvider(JpaConnectionProvider.class, "user-store").getEntityManager();
}
