android – Dagger 2.2元件構建器模組方法已棄用

我開始使用匕首2.2,並且不建議使用“元件”構建器中的模組方法.

這是我的應用程式元件：

@Component(modules = ApplicationModule.class)
public interface ApplicationComponent {
void inject(Application application);
}

和應用模組：

@Module
public class ApplicationModule {
Application application;

public ApplicationModule(Application application) {
this.application = application;
}

@Provides
@Singleton
Application providesApplication() {
return application;
}
}

這是生成的類：

@Generated(
value = "dagger.internal.codegen.ComponentProcessor",
comments = "https://google.github.io/dagger"
)
public final class DaggerApplicationComponent implements ApplicationComponent {
private DaggerApplicationComponent(Builder builder) {
assert builder != null;
}

public static Builder builder() {
return new Builder();
}

public static ApplicationComponent create() {
return builder().build();
}

@Override
public void inject(Application application) {
MembersInjectors.<Application>noOp().injectMembers(application);
}

public static final class Builder {
private Builder() {}

public ApplicationComponent build() {
return new DaggerApplicationComponent(this);
}

/**
* @deprecated This module is declared, but an instance is not used in the component. This method is a no-op. For more, see https://google.github.io/dagger/unused-modules.
*/
@Deprecated
public Builder applicationModule(ApplicationModule applicationModule) {
Preconditions.checkNotNull(applicationModule);
return this;
}
}
}

如果不使用ComponentBuilder,如何初始化元件？

您應該閱讀關於為什麼不被棄用的說明.如果您正在使用像IntelliJ或Android+Studio/">Android Studio這樣的IDE,您只需選擇該方法並在Windows上點選Control Q即可閱讀Javadoc,包括棄用通知.

Javadoc讀取：

@deprecated This module is declared, but an instance is not used in the component. This method is a no-op. For more, see 07000.

從這個連結可以看到：

可以肯定地說,您可以忽略棄用.它旨在通知您未使用的方法和模組.一旦您在子圖中實際需要/使用應用程式,就需要使用模組,棄用警告將會消失.
