Stefan Schulze commented on HHH-7312:
-------------------------------------
Ok, doesn't matter if we call it bug or feature.
You said it'd be possible to repurposing CurrentTenantIdentifierResolver. Could you
outline, what would be necessary to do this? If it's simply done by changing the
javadoc or something I can resolve, I would create a feature request about repurposing the
Resolver, add both pull-requests (329 and 338) to this feature-request and link HHH-7306
and HHH-7312 as fixed by the feature request.
Is this a viable solution?
Allow usage of multi-tenancy from HEM
-------------------------------------
Key: HHH-7312
URL:
https://hibernate.onjira.com/browse/HHH-7312
Project: Hibernate ORM
Issue Type: New Feature
Components: entity-manager
Affects Versions: 4.1.2
Environment: Hibernate 4.1.2, using JPA
Reporter: Oriel Maute
Priority: Minor
Labels: jpa2, multi-tenancy
Attachments: persistence.xml, SchemaBasedMultiTenancyTest.java,
SchemaBasedMultiTenantConnectionProvider.java, SchemaBasedTenantResolver.java
Original Estimate: 1h
Remaining Estimate: 1h
I tried to use db schema based multi tenancy with hibernate jpa / entitymanager. I use
the following properties in persistence.xml:
<property name="hibernate.multiTenancy" value="SCHEMA"/>
<property name="hibernate.tenant_identifier_resolver"
value="com.xoricon.persistence.bo.multitenancy.test.SchemaBasedTenantResolver"/>
<property name="hibernate.multi_tenant_connection_provider"
value="com.xoricon.persistence.bo.multitenancy.test.SchemaBasedMultiTenantConnectionProvider"/>
Both instances (SchemaBasedTenantResolver / SchemaBasedMultiTenantConnectionProvider)
will be instantiated by hibernate.
When i call:
EntityManagerFactory lEntityManagerFactory=
Persistence.createEntityManagerFactory("orm1");
EntityManager lManager = lEntityManagerFactory.createEntityManager();
I get:
System.out: SchemaBasedMultiTenantConnectionProvider.getAnyConnection()
System.out: SchemaBasedTenantResolver.<init>()
E

There was 1 error:

FAILURES!!!
Tests run: 1, Failures: 0, Errors: 1
In System.out "SchemaBasedTenantResolver.<init>()" shows, that my
CurrentTenantIdentifierResolver has been instantiated. But Hiberante did not call method
"public String resolveCurrentTenantIdentifier()".
I expect, that Hibernate uses the CurrentTenantIdentifierResolver to get the current
tenant id.
In JPA i cannot set the tenant on the Session, because the exception above occures before
Session has been created. I can access the Session only by EntityManager.getDelegate().
But as shown above, i cannot create an EntityManager instance.
