java - 返回 MembersInjectors.injectMembers 时出错

Question

我正在开发一个具有 Dagger 依赖项的 Android 应用程序。通过构造函数注入(inject)注入(inject)类时，会抛出找不到符号的错误。如果我通过模块内定义的 @Provides 方法提供依赖项，一切正常。

import java.util.List;
import rx.Observable;
import rx.Observer;
import javax.inject.Inject;
/**
 * Created by ibrahim on 22/05/18.
 * get injected View that MainView
 */
public class BakePresenter extends BasePresenter<MainView> implements Observer<BakingResponse> {


  @Inject
  protected BakeApiService mApiService;

  @Inject
  protected BakeMapper mBakeMapper;

  @Inject
  public BakePresenter() {
    }
    public void geBaking() {
      getView().onShowDialog("Loading.....");

      Observable<BakingResponse> bakePresenterObservable= mApiService.getBake();
      subscribe(bakePresenterObservable,this);
  }

  @Override
  public void onCompleted() {
    getView().onShowToast();
    getView().onHideDialog("Loading completed.....");

  }

  @Override
  public void onError(Throwable e) {
    getView().onShowToast();
    getView().onHideDialog("Loading error....."+String.valueOf(e.getMessage()));

  }

  @Override
  public void onNext(BakingResponse bakingResponse) {
    List<Bake> bakeList= mBakeMapper.mapBake(bakingResponse);
    getView().onBakeLoaded(bakeList);
  }
}

这是 Bakemodule 类

@Module
public class BakeModule {

    private MainView mView;

    public BakeModule (MainView view){
        this.mView=view;
    }


    @PreActivity
    @Provides
    MainView provideMainView(){
        return mView;
    }

 
    BakeApiService provideBakeApiService(Retrofit retrofit){
        return retrofit.create(BakeApiService.class);
    }
   
    @PreActivity
    @Provides
    public BakeApiService bakeApiService(final MembersInjector<BakeApiService> injector, final Retrofit retrofit) {
        Log.d("service", "station service created");
        BakeApiService bakeApiService = provideBakeApiService(retrofit) ;

        injector.injectMembers(bakeApiService);
        return bakeApiService;
    }
}

这是 BakeComponent

@PreActivity
@Component (modules = BakeModule.class,dependencies = ApplicationComponent.class)
public interface BakeComponents {

    /**
     * @param activity the Components want inject into inside MainActivity
     */


    void inject(MainActivity activity);
    MainView gMainView();
}

这是错误的

这是build.gradle

apply plugin: 'com.android.application'


android {
    compileOptions.incremental = false

    defaultConfig {

implementation "com.google.dagger:dagger:2.14.1"
annotationProcessor 'com.google.dagger:dagger-compiler:2.11'

您使用的 Dagger 注释处理器和库版本不匹配。虽然您永远不应该使用与您包含的库不同的代码生成器版本，但您遇到这个特定问题是因为 as of Dagger 2.14, MembersInjector.injectMembers was removed ，并且 Dagger 2.14 及更高版本生成的代码不引用该方法。

如 the Dagger readme file ，删除这两行并添加这些，这将使您保持在最新版本的 Dagger 2 上:

implementation 'com.google.dagger:dagger:2.x'
annotationProcessor 'com.google.dagger:dagger-compiler:2.x'
