Version: @angular@2.0.0

xhttp is an encapsulation service for http service.

@injectable()
export class Xhttp {
    constructor (@Inject(Http) private http: Http) {}
}

Originally, this part of the service was written under Project A, but considering reuse, it was planned to be made into a separate module. After proposing it, using npm to install the above code, an error will be reported:

No provider for Http!

This module has been introduced in the provider in the top-level module.

Please also help me take a look.
