匕首2-为什么这是一个依赖周期? [英] Dagger 2 - Why is this a dependency cycle?
本文介绍了匕首2-为什么这是一个依赖周期?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试将应用程序的 Context
注入其他2个对象中,即 AuthManager
和 ApiClient
。
I'm trying to inject the application's Context
into 2 other objects, an AuthManager
and an ApiClient
.
两者都取决于上述上下文,而 ApiClient
取决于 AuthManager
。如果 Context
没有引用其他2,为什么这是一个依赖循环?
Both of them depends on said context, and the ApiClient
depends on the AuthManager
. Why is this a dependency cycle, if Context
doesn't have a reference to the others 2? can this be solved?
编辑:这是一些代码
@Module
public class AppModule {
private final Application application;
public AppModule(Application application) {
this.application = application;
}
@Provides @Singleton
Context provideApplicationContext() {
return this.application;
}
}
@Module
public class NetworkModule {
@Provides @Singleton
public AuthManager providesAuthManager(AuthManager manager) {
return manager;
}
@Provides @Singleton
public ApiClient providesApiClient(ApiClientFactory factory) {
return factory.create();
}
}
@Singleton
@Component(modules = {AppModule.class, NetworkModule.class})
public interface ApplicationComponent {
void inject(BaseActivity activity);
// Exported for child-components
Context context();
ApiClient apiClient();
AuthManager authManager();
}
推荐答案
@Provides @Singleton
public AuthManager providesAuthManager(AuthManager manager) {
return manager;
}
您的提供AuthManager
方法提供 AuthManager
取决于 AuthManager
。
有你的周期:)
