Generate entities with cascade delete

I am generating entities for our large database via JBoss hibernate reverse engineering. I was hoping to see cascade annotations in entities, but did not see them on generation.

Is there a way to direct hibernate to consider foreign keys and generate entities with cascade annotations?

Unfortunately, it hasn't been documented although this is possible. It should have been documented at 6.2.4.3. foreign-key.

Look at hibernate-reverse-engineering-3.0.dtd, there's a cascade attribute in elements :

  • foreign-key/many-to-one
  • foreign-key/one-to-one
  • foreign-key/inverse-one-to-one
  • foreign-key/set

The code is the truth ! Looking at it (hibernate-tools branch 5.2), we can see the possible values of cascade :

For Hibernate in org.hibernate.tool.hbm2x.pojo.EntityPOJOClass#getHibernateCascadeTypeAnnotation : https://github.com/hibernate/hibernate-tools/blob/5.2/src/java/org/hibernate/tool/hbm2x/pojo/EntityPOJOClass.java#L497
Values are [ all-delete-orphan, delete-orphan, save-update, replicate, lock, evict ] (multiple accepted).
The enum type used is org.hibernate.annotations.CascadeType.

For JPA in org.hibernate.tool.hbm2x.pojo.EntityPOJOClass#getCascadeTypes : https://github.com/hibernate/hibernate-tools/blob/5.2/src/java/org/hibernate/tool/hbm2x/pojo/EntityPOJOClass.java#L421
Values are [ persist, merge, delete, refresh, all ] (multiple accepted).
The enum type used is javax.persistence.CascadeType.
