Java 多端点dagger2改造

对于我的项目，我需要使用2个不同的API端点。现在，我已经实现了dagger2代码，它只使用一个端点。有人知道吗，我如何在代码中正确地添加另一个端点

这是我的申请文件：

public class TalisProjectApplication extends Application {

@Inject
DataManager dataManager;
ApplicationComponent applicationComponent;

@Override
public void onCreate() {
    super.onCreate();

    applicationComponent = DaggerApplicationComponent.builder()
            .applicationModule(new ApplicationModule(this, FirebaseService.ENDPOINT, FirebaseService.ENDPOINT_ADS))
            .build();
    applicationComponent.inject(this);
}

public static TalisProjectApplication get(Context context) {
    return (TalisProjectApplication) context.getApplicationContext();
}

public ApplicationComponent getComponent() {
    return applicationComponent;
}

}

这是我的匕首档案

@Module
public class ApplicationModule {
protected final Application application;
String baseUrl;
String baseAdsUrl;
private LoginActivity activity;

public static final String FIREBASE = "firebase";
public static final String ADS = "ads";

public ApplicationModule(Application app, @Named(FIREBASE) String url, @Named(ADS)String baseAdsUrl) {
    application = app;
    this.baseUrl = url;
    this.baseAdsUrl = baseAdsUrl;
}

@Provides
Application provideApplication() {
    return application;
}

@Provides
@ApplicationContext
Context provideContext() {
    return application;
}

@Provides
@Singleton
SharedPreferences providesSharedPreferences(Application application) {
    return PreferenceManager.getDefaultSharedPreferences(application);
}

@Provides
@Singleton
Cache provideHttpCache(Application application) {
    int cacheSize = 10 * 1024 * 1024;
    Cache cache = new Cache(application.getCacheDir(), cacheSize);
    return cache;
}

@Provides
@Singleton
Gson provideGson() {
    GsonBuilder gsonBuilder = new GsonBuilder();
    gsonBuilder.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES);
    return gsonBuilder.create();
}

@Provides
@Singleton
OkHttpClient provideOkhttpClient(Cache cache) {
    HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
    logging.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient.Builder client = new OkHttpClient.Builder();
    client.addInterceptor(logging);
    client.cache(cache);
    return client.build();
}

@Provides
@Singleton
@Named(FIREBASE)
Retrofit provideRetrofit(Gson gson, OkHttpClient okHttpClient) {
    return new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .baseUrl(baseUrl)
            .client(okHttpClient)
            .build();

}


@Provides
@Singleton
@Named(ADS)
Retrofit provideAdsRetrofit(Gson gson, OkHttpClient okHttpClient) {
    return new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .baseUrl(baseAdsUrl)
            .client(okHttpClient)
            .build();

}

@Provides
@Singleton
@Named(FIREBASE)
FirebaseService.Firebase providesTheFirebaseService(@Named(FIREBASE) Retrofit retrofit) {
    return retrofit.create(FirebaseService.Firebase.class);
}

@Provides
@Singleton
@Named(ADS)
FirebaseService.Firebase providesTheAdsService(@Named(ADS) Retrofit retrofit) {
    return retrofit.create(FirebaseService.Firebase.class);
}
}

这是我使用改装电话的服务文件：

public class FirebaseService {

public static final String ENDPOINT = "";
public static final String ENDPOINT_ADS = "";
private static FirebaseService.Firebase firebase;

public interface Firebase {

}
}

在我尝试实现另一个端点之后。现在出现此错误：

改装2.如果没有@Inject构造函数，则无法提供改装 或者来自@Provides注释的方法

编辑

@Singleton
public class DataManager {

private Retrofit firebaseRetrofit;
private Retrofit adsRetrofit;
private FirebaseService.Firebase firebase;
private DatabaseReference databaseRef;
private Application application;
private PreferencesHelper preferencesHelper;

String catId;
@Inject
public DataManager(@Named(FIREBASE) Retrofit firebaseRetrofit, @Named(ADS) Retrofit adsRetrofit, FirebaseService.Firebase firebase, Application application, PreferencesHelper preferencesHelper) {
    this.firebaseRetrofit = firebaseRetrofit;
    this.adsRetrofit = adsRetrofit;
    this.firebase = firebase;
    this.application = application;
    this.preferencesHelper = preferencesHelper;
}
}

好吧，现在Dagger感到困惑，因为他不知道要为您的

数据管理器
提供什么
改装

您已在模块中声明了两个名为
的改装
实例。现在，您必须指定要传递给
DataManager
的
改造
实例：

@Inject
public DataManager(@Named(FIREBASE) Retrofit firebaseRetrofit,
                   @Named(ADS) Retrofit adsRetrofit,
                   ... ) {
    ...
}

在代码中显示您的
@Inject
改型
实例。仅使用一个改型url，我就在数据管理器中插入了改型实例。您可以在“编辑”中看到它。我没有使用@InjectAnnotation，它在没有它的情况下工作谢谢！现在出现此错误：错误：如果没有@Provides注释方法，则无法提供my.github.tomas.talisproject.data.remote.FirebaseService.Firebase。请参见如何在模块中提供
Firebase
实例。您已经用
@Named（FIREBASE）
对其进行了注释，这意味着您还必须在构造函数参数中对其进行注释。azizbekian感谢您的帮助，我编辑了您在我的帖子中所说的所有内容，但仍然出现相同的错误…@LaurisMacke，
我编辑了您在我的帖子中所说的所有内容
您没有。更改为
@Named（FIREBASE）FirebaseService.FIREBASE FIREBASE
。
@Inject
public DataManager(@Named(FIREBASE) Retrofit firebaseRetrofit,
                   @Named(ADS) Retrofit adsRetrofit,
                   ... ) {
    ...
}
