Envers and mappings

[iamdave]

I have a number of classes that have attributes which are interfaces rather than a concrete class and I'm getting " org.hibernate.MappingException: Type not supported for auditing: org.hibernate.type.AnyType" on each of these. Is there a workaround for this?

Thanks.

Hello,

how are these interfaces annotated?

I'm migrating to annotations so it's currently in XML

The audited class:

 <class name="com.test.Invoice" table="Invoice" >

 ...

 <any name="customer" meta-type="string" id-type="long" lazy="false">
 <meta-value value="STUDENT" class="com.test.Student" />
 <meta-value value="SCHOOL" class="com.test.School" />
 <column name="CUSTOMER_CLASS"/>
 <column name="CUSTOMER_ID"/>
 </any>
 </class>

Each class just has the @Audited annotation, there's no XML definition for the Customer interface.

Well, you are using the any-type, which isn't supported. This doesn't really has much to do with interfaces. Try using one-to-many or many-to-many.

Thanks for the guidance, I've just been moved onto this project so I'm not wholly familiar with hibernate but how could I rewrite the any clause with many-to-one clauses that reflect the same interface structure? Student and School both implement the Customer interface but need to inherit from another Class as well, so I can't rewrite a common ancestor class.

Hello,

well, you know, I can't tell you how you should map it without knowing the project ;). But it sounds as you need to use some inheritance schema. Or you could always add support for any-type mappings to Envers :)
