How to create and use a PanacheEntity class in Quarkus Extension?

[skku-daniilkim]

Hello,

I am writing an extension that contains a custom PanacheEntity in the runtime module. Without any build items, it does not get enhanced. To solve this, I added the following code in the deployment:

    @BuildStep
    AdditionalIndexedClassesBuildItem test(){
        return new AdditionalIndexedClassesBuildItem(
            FooEntity.class.getName(), BarEntity.class.getName()
        );
    }

Then, both entities' static methods get properly enhanced, and getters/setters added (can be examined via debugger), but, whenever my runtime module tries to modify the said entities, for example:

var foo = FooEntity.findById(1L);
foo.someMember = "changed";  // breakpoint here
foo.persistAndFlush();

Nothing happens. From further investigation, it turns out that foo.someMember = "changed" does not get enhanced, and instead of calling the appropriate generated setter, it just sets the value, since, if I try to manually call setSomeMember("changed") in the debugger on the specified breakpoint, everything works as expected.

So, what else should I do, so that I can properly use Panache in the Quarkus Extension code?

P.S. Registering the entities via AdditionalJpaModelBuildItem and PanacheEntityClassesBuildItem does not seem to do anything.

Your extension runtime should be indexed. See https://stackoverflow.com/a/55513723/56994 for how to make sure your runtime is indexed.

Once it's indexed, your classes which use the entities via field access will be found and enhanced by PanacheHibernateCommonResourceProcessor.replaceFieldAccesses().

Let me know if that helps?

Yes, I apologize for a stupid question.

The issue was that the extension not only has to index the PanacheEntity themselves, but also the classes that use them (where field accessors need to be replaced with getters/setters). Using the Jandex Plugin or explicitly adding the class that uses the panache entity to AdditionalIndexedClassesBuildItem (e.g., FooRepository), fixed the issue.

It's not stupid, thanks for asking and good to know you found a solution :)
