如何使用安卓Dagger2提供房间Dao依赖？

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

@Module
public class RoomModule {
    @Provides
    public UserDao provideUserDao(AppDatabase database) {
        return database.userDao();
    }
}

@Singleton
@Component(modules = {RoomModule.class})
public interface AppComponent {
    void inject(MainActivity activity);
}

public class MainActivity extends AppCompatActivity {
    @Inject
    UserDao userDao;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 创建AppComponent实例
        AppComponent appComponent = DaggerAppComponent.builder()
                .roomModule(new RoomModule())
                .build();

        // 注入依赖
        appComponent.inject(this);

        // 使用注入的依赖对象
        userDao.getUserList();
    }
}
