Hibernate DataSourceBasedMultiTenantConnectionProviderImpl does not work for Multitenancy ----------------------------------------------------------------------------------------- Key: WFLY-13617 URL: https://issues.redhat.com/browse/WFLY-13617 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Affects Versions: 19.1.0.Final, 20.0.0.Final Reporter: Rafael Sampaio Assignee: Scott Marlow Priority: Minor Hello All, I was using o the DataSourceBasedMultiTenantConnectionProviderImpl contained in Hibernate lib to perform DATABASE MultitenancyType up to Wildfly 18. Upgrading to version 19 (tested on 20 too), upon initialization of my application I get the error:   {noformat} 14:07:52,655 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 84) MSC000001: Failed to start service jboss.persistenceunit."web-5.0.0#appPU": org.jboss.msc.service.StartException in service jboss.persistenceunit."web-5.0.0#appPU": org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]14:07:52,655 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 84) MSC000001: Failed to start service jboss.persistenceunit."web-5.0.0#appPU": org.jboss.msc.service.StartException in service jboss.persistenceunit."web-5.0.0#appPU": org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] at org.jboss.as.jpa.service.PersistenceUnitServiceImpl$1$1.run(PersistenceUnitServiceImpl.java:198) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl$1$1.run(PersistenceUnitServiceImpl.java:128) at org.wildfly.security.manager.WildFlySecurityManager.doChecked(WildFlySecurityManager.java:658) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl$1.run(PersistenceUnitServiceImpl.java:212) at org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1982) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1486) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1377) at java.lang.Thread.run(Thread.java:748) at org.jboss.threads.JBossThread.run(JBossThread.java:485)Caused by: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:275) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:237) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:214) at org.hibernate.id.factory.internal.DefaultIdentifierGeneratorFactory.injectServices(DefaultIdentifierGeneratorFactory.java:152) at org.hibernate.service.internal.AbstractServiceRegistryImpl.injectDependencies(AbstractServiceRegistryImpl.java:286) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:243) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:214) at org.hibernate.boot.internal.InFlightMetadataCollectorImpl.<init>(InFlightMetadataCollectorImpl.java:179) at org.hibernate.boot.model.process.spi.MetadataBuildingProcess.complete(MetadataBuildingProcess.java:119) at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.metadata(EntityManagerFactoryBuilderImpl.java:1215) at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:1246) at org.jboss.as.jpa.hibernate5.TwoPhaseBootstrapImpl.build(TwoPhaseBootstrapImpl.java:44) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl$1$1.run(PersistenceUnitServiceImpl.java:170) ... 9 more Caused by: org.hibernate.HibernateException: Improper set up of DataSourceBasedMultiTenantConnectionProviderImpl at org.hibernate.engine.jdbc.connections.spi.DataSourceBasedMultiTenantConnectionProviderImpl.injectServices(DataSourceBasedMultiTenantConnectionProviderImpl.java:80) at org.hibernate.service.internal.AbstractServiceRegistryImpl.injectDependencies(AbstractServiceRegistryImpl.java:286) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:243) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:214) at org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator.buildJdbcConnectionAccess(JdbcEnvironmentInitiator.java:149) at org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator.initiateService(JdbcEnvironmentInitiator.java:66) at org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator.initiateService(JdbcEnvironmentInitiator.java:35) at org.hibernate.boot.registry.internal.StandardServiceRegistryImpl.initiateService(StandardServiceRegistryImpl.java:94) at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:263) ... 21 more{noformat} The error happens inside this implementation:     {noformat} public void injectServices(ServiceRegistryImplementor serviceRegistry) { final Object dataSourceConfigValue = serviceRegistry.getService( ConfigurationService.class ) .getSettings() .get( AvailableSettings.DATASOURCE ); if ( dataSourceConfigValue == null || ! String.class.isInstance( dataSourceConfigValue ) ) { throw new HibernateException( "Improper set up of DataSourceBasedMultiTenantConnectionProviderImpl" ); } ...{noformat} The changed behavior is that the the parameter is no longer a String, but a WildFlyDataSource.   I'm opening this case just to check if this is the expected behavior, and I should really override the necessary part of the code in order to circumvent the error or was this some sort of regression?
