Possibility to define order for invoking @PostConstruct

[Simecsek Timothy <Ti...@nttdata.com>]

Hello,



I'm looking for a way to ensure initialization order for domain service annotated with @PostConstruct.



I have a self defined domain service for application settings that uses the one of isis enhanced with caching. During unit tests I found that always a other domain service is instantiated that uses my application settings domain service.



Class name for my application settings: SettingsClient

Dependent class name: HostSync



Is it dependent from the name or is there some annotation that I can use?



Thanks!

Timothy

Hi Timothy,

There's no feature in Isis that lets you define the order of
initialization, I'm afraid.

And because we are using the JEE @PostConstruct annotation [1], I suspect
that it is "bad form" to require some sort of ordering.

~~~
>From the description of your problem I'm not sure that ordering is what you
need; rather that it seems that there's some ambiguity in terms of having
two similar services being available.

In JEE the @Qualifier annotation can help with this, but unfortunately we
haven't yet implemented that in Isis.

A workaround might be to define a subinterface and ensure that only one of
your domain services implements that interface.  That might work.

Could you post some additional snippets of your code to see if we can
figure out a solution for you ?


Cheers
Dan
