Life-cycle methods for services in angular2 : <p>Is it possible to have life-cycle hooks for a service that is annotated with <code>@Injectable()</code>?</p>

<p>I'd have expected the life-cycle hooks to be called on a service like this, but I was proven wrong, it seems to be working on <code>@Component</code> only. Is there a way to get informed in a service when dependency injection creates / destroys a service?</p>

<pre><code>import {Component, Injectable, OnInit, OnDestroy} from 'angular2/core';

@Injectable()
export class SampleService implements OnInit, OnDestroy {
    ngOnInit() {
        console.log("OnInit")
    }
    ngOnDestroy() {
        console.log("OnDestroy")
    }
}

@Component({
  selector: "sample",
  template: "&lt;div&gt;Sample Component&lt;/div&gt;",
  providers: [ SampleService ]
})
export class SampleComponent {
  constructor() { private _sampleService: SampleService }
}
</code></pre>
