| To create DTO's (lighter object, that don't map the whole table/jointable of an object) it should be possible to map multiple entities to the same table. This would be a very convenient way to create DTO's! Right now it's not possible to create a schema like this due to the following exception: Caused by: org.hibernate.DuplicateMappingException: Duplicate table mapping SubClass1 Could this become a warning instead of an exeception? Or a @IgnoreDuplicateTableMapping annotation of some sort? See also the following stackoverflow issue that goes into more detail: http://stackoverflow.com/questions/30071394/data-transfer-object-dto-hibernate-duplicate-table-mapping |
