Hi We upgraded spring orm from 4.2.9 to 5.0.8 and Hibernate from 5.1.1 to 5.6.15  
and still using hbm.xml files for mapping and not using annotations.  
Replaced the org.springframework.orm.hibernate4.LocalSessionFactoryBean with  
org.springframework.orm.hibernate5.LocalSessionFactoryBean.

During runtime/deployment getting following error, your help is appreciated:

Context initialization failed  
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘indexController’: Injection of r  
esource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException:  
Error creating bean with name ‘userServiceImpl’: Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException:  
Error creating bean with name ‘xxDao’: Injection of resource dependencies failed;

Please share the full stack trace and the hbm.xml mapping.

The stack trace is still missing the relevant stack frames that point to the Hibernate ORM source code of where the exception originate.  
Also, what you posted is your Spring configuration file, but what I need to see is the hbm.xml mapping for the entity which causes this exception.

This is still not the stack trace that I need, the essential part is cut off.

The correct stack trace should contain stack frames that point to the `org.hibernate.metamodel.internal.AttributeFactory` class

Now, please set a debug break point at `AttributeFactory` on line 1023 and figure out for which entity this error happens. Finally, please post the hbm.xml contents for that entity.

Error does not specify exactly which hbm.xml file is throwing error.  
It looks like Hibernate is expecting IdClass annotation even though my legacy code does not use annotations at all, we are still using hbm.xml files that has composite-ids.  
I am not understanding why it is expecting annotations ?  
Example of hbm.xml file:

\<?xml version="1.0" encoding="utf-8"?\>

If you set the break point where I suggested, you can go to earlier stack frames and figure out for which entity this method was called. Without that information, nobody can help you.

I understand what you are saying.But my question is why it is expecting annotations (IdClass) in regular pojo classes ?

This exception happens when instantiating the JPA static metamodel, which as you can imagine, is **not** specially implemented for every mapping source. Hibernate ORM uses the same code paths and since annotation mapping is the most common, encountered errors will refer to the annotation mapping parts in their exception message.

Thank you for your help, figured out the issue.One of the hbm.xml file does not have the name attribute for composite-id, that seems to be causing the issue.

Please share the relevant hbm.xml fragments that you had before and show what you changed so that others that run into this issue might possibly also benefit from this discussion.
