I guess then you are on your own.
I don't think Guice provide such a feature out of the box.
You could write a custom Module which reads the properties files and
creates bindings for each and every one.
As long as all of them are simple just like the examples you gave I
think you should be able to get this done in a few lines of code.
But I don't know Spring enough to tell if there are complex cases which
you would also need to support...
Good luck
And if you have any concrete question don't hesitate to ask

The reason for binding as properties is basically backwards
compatibility. This is a legacy system originally built with spring.
I'm trying to move to guice because spring is way too heavy and takes
a long time to start, but all of this works out of the box.
Unfortunately, having each plugin ship with a module is not an option
in this case, which is why I'm looking for a way to leverage guice
goodies while while keeping spring's behavior.
Thanks

I don't think this would be a good approach. And I am not even
sure if guice would allow it.
I would rather propose that every plugin comes with a Module which
is then passed to the injector creation method.
This way every plugin can bind whatever it needs.
If multiple plugins try to bind the same thing you could always
encapsulate a plugin in a private module and only expose a limited
set of bindings.
If I miss the point here then maybe try to explain why you are
passing bindings in properties files...

Thank you.
Yes I looked at Multibinders but this still requires the brute
force approach. Each of my plugins can register any random
object, I don't know the universe of interfaces before hand. I
was more looking in the direction of somehow tapping into how the
bindings are processed so that when Guice realises that it
cannot serve @Inject FooService I can catch that and calculate
that binding on demand?
Is this or something like that possible?
Thanks

Then bind all possible implementations of an interface and
use the value from the properties to select the one out of
the set.

Hello,
I have a case in which a portion of the binding are
dynamically provided through a properties file with the
following format:
|
exampleService=ExampleServiceImpl
fooService=FooServiceImpl
|
Unlike Guice's approach, the key is not a type but an actual
Name. For now, I'm just binding those concrete types to
themselves, like
/bind(FooServiceImpl.class).to(bindFooServiceImpl.class)/
Of course this approach doesn't work because then the
following injection would fail:
|
publicclassFoo{
@Inject
privateFooServicefooService;
}
|
There's no default way in which Guice would figure out that
FooService can actually be served by FooServiceImpl. The
alternative that I have thought about so far is to
introspect those types and generate bindings for each
superclass and implemented interface.
I was wondering is there's a less "brute force" approach.
Thanks
