[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-642) hbm2ddl is generating tables for classes annotated with @MappedSuperclass

hbm2ddl is generating tables for classes annotated with @MappedSuperclass ------------------------------------------------------------------------- Key: ANN-642 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-642 Project: Hibernate Annotations Issue Type: Bug Components: binder Environment: Hibernate 3.2 MySQL 5 Reporter: Ezra Epstein I've a class annotated as: @Entity @MappedSuperclass public abstract class BaseUuidKeyedEntity implements Serializable { ... } The relevant section of the EJB3 persistence spec reads, in part: "9.1.36 MappedSuperclass Annotation The MappedSuperclass annotation designates a class whose mapping information is applied to the entities that inherit from it. A mapped superclass has no separate table defined for it. A class designated with the MappedSuperclass annotation can be mapped in the same way as an entity except that the mappings will apply only to its subclasses since no table exists for the mapped superclass itself...." So no Table should be associated with this class. Yet the resultant DDL includes: create table BaseUuidKeyedEntity ( uuid varchar(31) not null, create_ts datetime, update_ts datetime, versionNum integer, primary key (uuid) );
