Hi
I have the following setup:
Injector-ModuleA-ChildInjectorA-ModuleB-ChildInjectorB-ModuleC-FinalChildInjector
\-----------ModuleD--------/
ModuleA is the core project where all base stuff are setup like JPA etc..
ModuleB needs to use JPA(get it injected), so therefore it needs to be
installed in childInjectorA
ModuleC & ModuleD uses stuff in ModuleB so therefore needs to be in
childInjectorB so that it can get stuff from childinjectorA injected.
Problem are the one of the components in ModuleD gets this "It was
already configured on one or more child injectors or private modules"
to one of the references from ChildInjectorB which are strange since I
only define the class once. Intially I was not using private modules,
I've also tried using them and exposing the problematic interfaces but
it still fails.
Are there another way of getting things injected into modules? If I
somehow could use just one Injector it would probably work, but in
order todo that I need guice to manage the module instead of what I am
doing now:
Pseudo code:
Injector injector= Guice
.createInjector(new ModuleA());
ModuleB moduleB= new ModuleB();
injector.injectMembers(moduleB);
injector= injector.createChildInjector(moduleB);
ModuleC moduleC= new ModuleC();
ModuleD moduleD= new ModuleD();
injector.injectMembers(moduleC);
injector.injectMembers(moduleD);
injector= injector.createChildInjector(moduleC,
moduleD);
Heres the full stack (real code), WallboardDataDriverModule=ModuleB and :
