Dagger 2無法解析符號'DaggerAppComponent'

Question

我正在嘗試創建一個簡單的應用程序，其中包含retrofit 2，匕首2和MVP，但我與依賴關係糾纏在一起，實際上，這是我嘗試重建項目錯誤：執行任務'：app：compileDebugJavaWithJavac'失敗。

java.lang.StackOverflowError

以及在App類，我提供AppComponent：不能解析符號「DaggerAppComponent」

我會向你們展示我的項目是什麼樣子所以有人看到了問題，第一個是我的AppModule其中包括PresentationModule.class

@Module(includes = PresentationModule.class) 
public class AppModule { 
    private App app; 

    public AppModule(App app) { 
     this.app = app; 
    } 

    @Provides 
    @Singleton 
    public App provideApp() { 
     return app; 
    } 
} 

提示部看起來是這樣的：

@Module(includes = InteractorModule.class) 
public class PresentationModule { 

    @Provides 
    JokePresenter providePresenter(JokeInteractor jokeInteractor) { 
     return new JokePresenterImpl(jokeInteractor); 
    } 
} 

而且InteractorModule：

@Module(includes = {NetworkModule.class, PresentationModule.class}) 
public class InteractorModule { 

    @Provides 
    JokeInteractor provideJokeInteractor(RetrofitService service, JokePresenter presenter) { 
     return new JokeInteractorImpl(service, presenter); 
    } 
} 

這是具有基準以查看和交互件JokePresenter：具有RetrofitService和JokePresenter引用

public class JokePresenterImpl implements JokePresenter { 

    private JokeView mJokeView; 
    private List<String> mData = new ArrayList<>(); 
    private String mJoke; 
    private JokeInteractor jokeInteractor; 

    public JokePresenterImpl(JokeInteractor jokeInteractor) { 
     this.jokeInteractor = jokeInteractor; 
    } 

    @Override 
    public void setView(JokeView view) { 
     this.mJokeView = view; 
    } 

    @Override 
    public void getRandomJoke() { 
     mJokeView.showProgress(); 
     jokeInteractor.getRandomJoke(); 
    } 
} 

而且JokeInteractor：

public class JokeInteractorImpl implements JokeInteractor { 

    private RetrofitService retrofitService; 
    private JokePresenter presenter; 

    public JokeInteractorImpl(RetrofitService service, JokePresenter presenter) { 
     this.retrofitService = service; 
     this.presenter = presenter; 
    } 

    @Override 
    public void getRandomJoke() { 
     retrofitService.getRandomJoke() 
       .subscribeOn(Schedulers.io()) 
       .observeOn(AndroidSchedulers.mainThread()) 
       .subscribe(new Observer<RandomJokeResponse>() { 
        @Override 
        public void onCompleted() { 
         presenter.onRandomJokeCompleted(); 
        } 

        @Override 
        public void onError(Throwable e) { 
         presenter.onError(e.getMessage()); 
        } 

        @Override 
        public void onNext(RandomJokeResponse randomJokeResponse) { 
         presenter.onNextRandomJoke(randomJokeResponse); 
        } 
       }); 
    } 

搖籃依賴性：

apt 'com.google.dagger:dagger-compiler:2.7' 
    compile 'com.google.dagger:dagger:2.7' 
    provided 'javax.annotation:jsr250-api:1.0' 

    //retrofit 
    compile 'com.squareup.retrofit2:retrofit:2.1.0' 
    compile 'com.squareup.okhttp:okhttp:2.5.0' 
    compile 'com.squareup.retrofit2:converter-gson:2.1.0' 
    compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0' 

    //rx java 
    compile 'io.reactivex:rxjava:1.1.6' 
    compile 'io.reactivex:rxandroid:1.2.1' 

//dagger2 
    compile 'com.google.dagger:dagger:2.0' 
    provided 'org.glassfish:javax.annotation:10.0-b28' 

有人可以在這裏看到問題嗎？

Answer 1

看的實現：

@Module(includes = InteractorModule.class) 
public class PresentationModule 

和

@Module(includes = {NetworkModule.class, PresentationModule.class}) 
public class InteractorModule 

你有一個循環依賴。你需要重新考慮你的設計。我建議從Presenter去耦Interactor。

一個簡單的辦法：

變化getRandomJoke()實現返回Observable和訂閱它裏面Presenter。並從Interactor中刪除presenter參考。

交互器：

public class JokeInteractorImpl implements JokeInteractor { 

    private RetrofitService retrofitService; 

    public JokeInteractorImpl(RetrofitService service) { 
     this.retrofitService = service; 
    } 

    @Override 
    public Observable getRandomJoke() { 
     return retrofitService.getRandomJoke() 
      .subscribeOn(Schedulers.io()) 
      .observeOn(AndroidSchedulers.mainThread()); 
    } 
} 

主持人：

@Override 
public void getRandomJoke() { 
    mJokeView.showProgress(); 
    jokeInteractor.getRandomJoke() 
      .subscribe(new Observer<RandomJokeResponse>() { 
       @Override 
       public void onCompleted() { 
        onRandomJokeCompleted(); 
       } 

       @Override 
       public void onError(Throwable e) { 
        onError(e.getMessage()); 
       } 

       @Override 
       public void onNext(RandomJokeResponse randomJokeResponse) { 
        onNextRandomJoke(randomJokeResponse); 
       } 
      }); 
}
