Assisted inject doesn't work with boolean #811

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Description of the issue:
Assisted inject doesn't work with boolean, version 3.0

Steps to reproduce:
1. Code for Factory interface:
public interface RedirectorFactory {
    public Redirector  build(
            @Assisted("endpoints") EndpointsConfig endpoints,
        @Assisted("redirectUrl") String redirectUrl,
        @Assisted("redirectQuery") String redirectQuery,
        @Assisted("mobile") boolean mobile);
}
2. Constructor for Object:
    @Inject
    public Redirector(
            EndpointsConfig endpoints, String redirectUrl,
            String redirectQuery,
            boolean mobile) {...}
3. Code that executes:
        Redirector redirector = redirectorFactory.build(endpoints, pureRedirectUrl, pureRedirectQuery, pureMobile);
4. Getting:
1) Could not find a suitable constructor in java.lang.Boolean. Classes must 
have either one (and only one) constructor annotated with @Inject or a 
zero-argument constructor that is not private.

The @Inject'd class doesn't have the assisted parameters annotated with 
@Assisted.  The injection is failing because there's no boolean injection point 
in your main injector, and assistedinject doesn't know that it needs to assist 
it.

It doesn't work without @Assisted("mobile") too.

Please post the newer stack trace & a minimal test-case that produces the 
failure.

I'm 100% certain that it has nothing to do with "boolean" not working with 
assistedinject, as we have a ton of code that successfully does that.

Keep in mind that if you intended to assist the other parameters, you should 
mark those as @Assisted too, otherwise Guice will inject them from the main 
injector, not from your factory-supplied arguments.

Solution:
Looks like I've understand your point. Posting here a solution in case of 
somebody else is as dumb as me. 

Factory:

public interface RedirectorFactory {
    public Redirector  build(
             EndpointsConfig endpoints,
            @Assisted("redirectUrl") String redirectUrl,
            @Assisted("redirectQuery") String redirectQuery,
            boolean mobile);
}
Constructor:
    @Inject
    public Redirector(
            @Assisted EndpointsConfig endpoints,
            @Assisted("redirectUrl") String redirectUrl,
            @Assisted("redirectQuery") String redirectQuery,
            @Assisted boolean mobile) {
