I am trying to model a many-to-many relationship with a composite element and a many-to-one tag, but am getting an error. Any help would be appreciated.
I have a User, Role and UserRole tables. The UserRole table holds the many-to-many relationship. I am only interested in the one way mapping - there is no mapping to the User from the Role object.
In the User mapping file:
Code:
<set name="roles" table="USER_ROLE" cascade="all-delete-orphan">
<key column="USER_ID"/>
<composite-element class="com.biperf.core.domain.user.UserRole">
<property name="createdBy" column="CREATED_BY" type="java.lang.String" />
<many-to-one name="role" class="com.biperf.core.domain.user.Role" />
</composite-element>
</set>
The UserRole class:
Code:
public class UserRole
{
private Role role;
private User user;
private String createdBy;
//getters and setters removed in post...
}
The exception I am getting on a session.flush():
Code:
org.hibernate.PropertyAccessException: exception getting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of com.biperf.core.domain.user.UserRole.?
