[cdi-dev] [JBoss JIRA] (CDI-590) Provide a way to produce any type in a producer

[Romain Manni-Bucau (JIRA)]

Romain Manni-Bucau commented on CDI-590:
----------------------------------------

[~mkouba] yes. Suppose you have a configuration library or another IoC you want to integrate with for instance. In such cases you often have SuperFrameworkFactory.getBean(Type, Annotation, OtherParamLibSpecific) and you just can to call this building the parameters from the InjectionPoint. Today the only solution with CDI is to build an extension where you would just produce the bean and ensure it is not ambiguous using a qualifier.

> Note: this is a follow up "adding generic producers to CDI 2.0?" thread on the list
> It is common to rely on a subsystem (another IoC, a coercing system, ...) to produce values. Today a producer can't say "I produce anything in a safe" manner.
> Idea would be for injection point aware producers with a qualifier to producer Object and match all types.
> It needs another flag (can be in @Qualifier or another annotation it is not really important) to say "I produce safely any type".
> I did a PoC on github: https://github.com/rmannibucau/generic-producer-cdi but think it can be a nice feature of CDI 2.0 since it would avoid users to have to dig into extensions for several simple cases (configuration, bridge to other IoC...)
