Applications that utilize JPA will automatically have the Hibernate classes injected onto the application deployment classpath. You can inject a org. Session and org. The Hibernate ORM 5. For applications that use the Hibernate ORM 5. For details on the Hibernate 5. For this reason, we made it easy to enable the transformer via either a system property or jboss-deployment-structure change. In user type classes, change methods with parameter type org.
SessionImplementor to instead use type org. SharedSessionContractImplementor, this is done for implementations of:. In user type classes, when calling org. Change calls to org. FlushMode, to instead reference FlushMode. Example output:. WildFly automatically sets the following Hibernate properties if not already set in persistence unit definition :. New applications should let this default to true, older applications with existing data might need to set to false see note below. It really depends on whether your application uses the GeneratedValue AUTO which will generates new key values for newly created entities.

The application can override this value in the persistence. JtaPlatform interface. The transaction manager, user transaction and transaction synchronization registry is passed into Hibernate via this class. Scanner interface. Instance of entity scanning class is passed in that knows how to use the AS annotation indexer for faster deployment.

This property is removed if found in the persistence. The following properties are supported in the persistence unit definition in the persistence. Should be application, if a persistence provider is packaged with the application. See note below about some module names that are built in based on the provider.

The default is true, which enables container managed JPA access to the persistence unit. This is typically set to false for Spring applications. This is useful if you inject a persistence context without specifying the unitName PersistenceContext EntityManager em but have multiple persistence units specified in your persistence.
Setting the wildfly. Defaults to true. This is only important for persistence units that do not specify a datasource. Controls whether transaction scoped persistence context used in non-JTA transaction thread, will detach loaded entities after each EntityManager invocation or when the persistence context is closed e. Defaults to false entities are cleared after EntityManager invocation and if set to true, the detach is deferred until the context is closed.
Controls which version of Hibernate Search to include on classpath. Only makes sense when using Hibernate as JPA implementation. The default is auto; other valid values are none or a full module identifier to use an alternative version.
Specify the qualified application scoped persistence unit name to be used. The hibernate. Make sure you set the jboss. If set to true, allows an SynchronizationType. Otherwise, an IllegalStateException exception would of been thrown that complains that an unsychronized persistence context cannot be propagated into a synchronized persistence context.
Defaults to false.
Set up your environment
Set to true to disable the throwing of an IllegalStateException exception when propagating an SynchronizationType. This hint may be deprecated in a future release. See WFLY for more details. Only applies to Hibernate ORM 5. As mentioned above, if the jboss. The mapping is:.
However, you can explicitly configure this in the persistence. The value of that property should be the JNDI name to which the entity manager factory should be bound.
XML and Java(TM): Developing Web Applications
As a reminder, a transaction scoped entity manager persistence context , acts as a proxy that always gets an unique underlying entity manager at the persistence provider level. This approach is the most efficient, and removes a potential single point of failure.
However, to make this possible, it does require that all names follow a strict layout, so user customizations are not possible. Currently only access to remote EJBs is supported via the ejb: namespace. The client then invokes a method on the proxy which results in another remote network call to the underlying service.
It does however allow for customized names, and for a centralised directory for multiple application servers. This centralized directory is, however, a single point of failure. This is useful in that it allows applications to only ever reference standard portable Java EE names in both code and deployment descriptors. This feature allows you to run an extremely minimal AS server around your application, so that you can take advantage of certain core services such as naming and injection.
