MappedSuperclass and inheritance in JPA

[agoncal]

Hi all,

I was wondering if it was possible to create MappedSuperclass with Forge and having entities extending thoses MappedSuperclasses. I couldn't find anything about JPA inheritance in general and nothing with MappedSuperclass nor Embeddeables. Is there a way ?

As a new comer in Forge (I had a look a the very first versions long time ago) I feel the commands are not that intuitive. I love the following :

java new-enum-type

java new-itnerface

java new-class

...

So I would expect to have something similar in JPA :

persistence new-entity (instead of entity --named)

persistence new-embedable

persistence new-mapped-superclass

Inheritance could just be an argument :

persistence new-mapped-superclass --named Person

persistence new-entity --named Vet --extends Person

Coming back to the command line, the following would make sense, don't you think ?

ejb new-stateless

ejb new-singleton

servlet new-filter

rest new-endpoint

My 2 cents

Hi Antonio,

Glad you're enjoying Forge.

These suggestions are really nice. Would you mind creating a JIRA[1] for each proposed feature ?

Thank you very much !

Btw, there is already an issue requesting the MappedSuperClass feature: https://issues.jboss.org/browse/FORGE-133

Heyy! Antonio! Great to see you!

What got you looking at Forge again? What are you doing with it?

I really like all of your ideas, and we will try to take them into account now that we have a chance to do some renaming on Forge 2. We are currently taking the following approach (single-level command keywords only).

jpa-setup

jpa-new-entity

jpa-new-field

So it would follow that mapped superclass would be something like this (or similar, depending on what this command actually does.) As george suggested, could you fill out a few JIRA issues to expand on these ideas? I like where you are headed with this

jpa-mapped-superclass

I hope to see you again soon!

Thanks!

Ok, here is a JIRA that will hopefully keep all the good ideas for naming conventions : https://issues.jboss.org/browse/FORGE-944

@lincoln I have this crazy idea of re-writing the Spring PetClinic in Java EE 7.... and thought of using Forge to kick it off (https://github.com/agoncal/agoncal-application-petclinic/blob/master/generate.fsh)

I'll be in JavaOne, hopefully I'll see you there ;o)

Not sure, none of my talks were accepted, but I'll keep my fingers crossed!

And that's a really nice idea! It would be awesome if it could be done entirely from forge. You'll have to let me know what is missing to make that happen! We can probably add features you need (but the renaming will have to wait for forge 2)

Cheers!

What I'm missing now is the possibility to create a MappedSuperclass and extend it. Something like that would do (not considering any naming) :

new-mapped-superclass --named Person

new-entity --named Vet --extends Person
