Question

我有一个类和接口。我正在尝试将接口对象注入到我的类构造函数中。类和接口在Kotlin中，而Dagger模块在Java中。

接口

interface PurchaseProductRest {
@POST
fun postPurchase(@Url url: String, @HeaderMap authHeaders: Map<String, String>, @Body request: InAppPurchase): Call<String>
}

班

class PurchaseProductCall @Inject constructor(val purchaseProductRest: PurchaseProductRest) {
private var authHeaders: HashMap<String, String>
private val TAG = "PurchaseProductCall"

init {
    authHeaders = HashMap()
}

fun ping() {
    Log.e(TAG, "succesful")
}

fun call(url: String, apiKey: String, authToken: String, inAppPurchase: InAppPurchase,
         apiResponse: Action1<String>) {
    authHeaders.clear()
    authHeaders["Authorization"] = authToken
    authHeaders["x-api-key"] = apiKey
    Log.d(TAG, "URL: $url")
    purchaseProductRest.postPurchase(url, authHeaders, inAppPurchase).enqueue(object : Callback<String> {
        override fun onFailure(call: Call<String>, t: Throwable) {

            //Log.e(TAG, "onFailure: " + t.getMessage());
            Observable.just(null as String)
                    .onErrorResumeNext { throwable: Throwable? -> Observable.empty() }
                    .subscribe(apiResponse)
        }

        override fun onResponse(call: Call<String>, response: Response<String>) {

            Observable.just<String>(response.body())
                    .onErrorResumeNext { throwable: Throwable? -> Observable.empty() }
                    .subscribe(apiResponse)
        }
    })
}
}

这是我的模块中的

 @Module
public class AppCMSUIModule {


    @Provides
    @Singleton
    public Gson providesGson() {
        return new GsonBuilder().registerTypeAdapterFactory(new Stag.Factory())
                .create();
        // return new Gson();
    }

    @Provides
    @Singleton
    public OkHttpClient providesOkHttpClient() {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.level(HttpLoggingInterceptor.Level.BODY);
        return new OkHttpClient.Builder()
                .connectTimeout(defaultConnectionTimeout, TimeUnit.MILLISECONDS)
                .writeTimeout(defaultWriteConnectionTimeout, TimeUnit.MILLISECONDS)
                .readTimeout(defaultReadConnectionTimeout, TimeUnit.MILLISECONDS)
                .addInterceptor(logging)
                .cache(cache)
                .build();
    }

    @Provides
    @Singleton
    public Retrofit providesRetrofit(OkHttpClient client, Gson gson) {
        return new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create(gson))
                .baseUrl(baseUrl)
                .client(client)
                .build();
    }

    @Provides
    @Singleton
    public PurchaseProductRest providesPurchaseProductRest(Retrofit retrofit) {
        return retrofit.create(PurchaseProductRest.class);
    }

    @Provides
    @Singleton
    public PurchaseProductCall providesPurchaseProductCall(PurchaseProductRest purchaseProductRest) {
        return new PurchaseProductCall(purchaseProductRest);
    }

}

另一个模块

@Module(includes = {AppCMSUIModule.class})
public class AppCMSPresenterModule {


@Provides
@Singleton
public AppCMSPresenter providesAppCMSPresenter(Gson gson,PurchaseProductCall purchaseProductCall){
    return new AppCMSPresenter(gson,purchaseProductCall);
}

}

构建应用程序时出现错误

 [ComponentProcessor:MiscError] dagger.internal.codegen.ComponentProcessor was unable to process this class because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.

有人可以指导我这里有什么问题吗？

Dagger 2：构造函数注入不适用于Android Kotlin？
