is hibernate-generic-dao 1.1.0 support hibernate 4.0?

[李 中伟]

hi
is hibernate-generic-dao 1.1.0 support hibernate 4.0? and if
support ,how to deploy,when i use hibernate 4.0 .it throws no this
method when sessionFactory.getCurrentSession()

[David W]

Has anyone else gotten this to work with Hibernate 4.0? I have to
admit that there is a bit of an architectural error in the framework
that hard-codes it to Hibernate 3.x, but I don't know if it may still
work with v 4.0 or not. Let us know if you have had experience getting
it to work with Hibernate 4.0.

Thanks.

David

If everyone has had trouble with this, an issue should probably be
logged in the Google code project.

There is an issue running against Hibernate4 due to API changes. It looks like the affected methods were deprecated around 3.5 and have now been removed. This is the error that I got:
java.lang.NoSuchMethodError: org.hibernate.metadata.ClassMetadata.getIdentifier(Ljava/lang/Object;Lorg/hibernate/EntityMode;)Ljava/io/Serializable;
    at com.googlecode.genericdao.search.hibernate.HibernateEntityMetadata.getIdValue(HibernateEntityMetadata.java:63)

Hey,
I just made it work with hibernate 4, by several code changes in the source.
How could I make a contribution to the project with my source?

I made some changes to the source code and it works. But hibernate4's get metadata's PK has changed,so I can not get the current session, so how you solve the transaction problem?

[Uri Ravzin]

* com.googlecode.genericdao.search.hibernate.HibernateEntityMetadata
Changed method parameters due to hibernate API changes
    * metadata.getIdentifier()
    * metadata.getMappedClass()
    * metadata.getPropertyValue()
* com.googlecode.genericdao.search.hibernate.HibernateNonEntityMetadata
Changed import package for org.hibernate.engine.spi

generic-dao’s version has not been updated from then on.

 

And generic-dao of version 1.x do not support hibernate v4.x.

 

So if you are using hibernate v4, you need import generic-dao’s source code  and modify it for your own usage.

Hi,

We currently use generic-dao on our project and would like to migrate to hibernate 4. Before we work on updating generic-dao's sources, is there any version we should start from? I can see a branch was created recently (Oct 28, 2012) but it does not seem that any code was then updated.

Thx,

Seems what is in need of change is HibernateEntityMetadata should do now:

getIdentifier(Object entity, SessionImplementor session);

instead of the old

getIdentifier(object, EntityMode.POJO);

However SessionImplementor I think it's an abstraction to get the hibernate-search as the concrete implementations are FullTextSessionImpl  and SessionImpl/StatelessSessionImpl, but I don't think that you ever inject with Spring the SessionImplementor so we can't just add it as a parameter in the constructor and it's not obtainable from the SessionFactory but rather it contains a SessionFactory.

In the end the IncrediblySillyJpaMapsIdMappedIdentifierValueMarshaller is used to get the id out of session.getPersistenceContext().getEntry( propertyValues[i] ); - session is of type SessionImplementor - so we need that to get the Hibernate PersistenceContext -.

Wow it seems that with hibernate4 JPA we really need to work through a bunch of layers and abstractions, makes you wonder if too much abstraction might not be that good at least not at midgnight.

[David W]

Okay. I'm back from my sabbatical and I'm working on the Hibernate 4 upgrade myself. I thought you added the "IncrediblySIlly" part just for fun, but now I see that it's actually in the Hibernate code base. Wow!

See http://code.google.com/p/hibernate-generic-dao/wiki/InstallationAndConfiguration for instructions on snapshot repo. I don't have any snapshots uploaded yet. I'll post when I do.
