T5 IOC Questions
First, I have a ton of DAOs that I need to bind the interface to the
implementation. I'd like to do this automatically, so I don't have to
keep modifying my AppModule for each DAO I create. What's the best way
to go about this? I figure if I can somehow get a ClassNameLocator
instance, I could just iterate through my package and do it that way.
However, how do I get a ClassNameLocator in bind(ServiceBinder)?
Second, on the SUPPRESS_REDIRECT_FROM_ACTION_REQUESTS issue, is it
possible to inject my own ActionRenderResponseGenerator that does my
bidding?

Not sure what I was doing wrong, but this works when added to my
AppModule:
public static void bind(ServiceBinder binder) {
binder.bind(ActionRenderResponseGenerator.class,
MyActionRenderResponseGenerator
.class).withId("MyActionRenderResponseGenerator");
}
public static void contributeServiceOverride(
@InjectService("MyActionRenderResponseGenerator")
ActionRenderResponseGenerator myService,
MappedConfiguration<Class<?>,Object> configuration) {
configuration.add(ActionRenderResponseGenerator.class, myService);
}

I've tried:
contributeAlias
contributeAliasOverride
contributeServiceOverride
None seem to actually override the ActionRenderResponseGenerator. Very
strange.

I did, but how do I get a ClassNameLocator in the bind() method so I
can then pass my classes to the ServiceBinder? bind() can only take a
single argument, and I can't inject something into the class, since
this is static.

I see that the InternalModule has a
buildActionRenderResponseGenerator() and I'd like replace that with my
own implementation. I'm just not sure how. I've tried a number of
things, including adding my own buildActionRenderResponseGenerator,
which fails due to duplication. I tried an alias, but can't get that
working either. What's the magic mojo to replace the
ActionRenderResponseGenerator service with something else in my
AppModule?

Alas, I just gave up. I wrote my own getClassesFromPackage() instead
of using ClassNameLocator and went with that. Seems to work.

ServiceBinder just has three bind() methods and nothing else
interesting. This one seemed promising:
<T> ServiceBindingOptions bind(Class<T> serviceInterface,
ServiceBuilder<T> builder);
However, I can't add stuff to the ServiceBinder from the
ServiceBuilder. And even with .eagerLoad(), buildServices() method
isn't called until after AppModule.bind() has finished. I can't see
how I can both add bindings while obtaining a ClassNameLocator.
Any other tips?

Look at the ServiceBinder interface; there are methods there
(especially in 5.1) that may address your needs.

Not following you here ... but in 5.1 it is possible to override
contributions as well as services.
