java可在室内流动

Question

@Database(entities = {User.class}, version = 2, exportSchema = false)
public abstract class AppDatabase extends RoomDatabase {
    public abstract userDao userDao();
}

Pojo用户类

@Entity
    public class User {
        @PrimaryKey(autoGenerate = true)
        private int id;

        public User(){
        }



        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }
    }

Dao

@Dao
public interface userDao {
            @Query("SELECT * FROM User WHERE id = :id")
            Flowable<User> get(int id);
            @Insert
            Completable insert(User user);
        }

依赖关系

implementation "安卓x.room:room-runtime:2.2.3"
annotationProcessor "安卓x.room:room-compiler:2.2.3"
implementation "安卓.arch.persistence.room:rxjava2:1.1.1"
implementation 'io.reactivex.rxjava2:rx安卓:2.1.1'
implementation "io.reactivex.rxjava2:rxjava:2.2.14"

错误

error: no suitable method found for createFlowable(RoomDatabase,boolean,String[],<anonymous Callable<User>>)
method RxRoom.createFlowable(RoomDatabase,String...) is not applicable
(varargs mismatch; boolean cannot be converted to String)
method RxRoom.<T>createFlowable(RoomDatabase,String[],Callable<T>) is not applicable
(cannot infer type-variable(s) T
(actual and formal argument lists differ in length))
where T is a type-variable:
T extends Object declared in method <T>createFlowable(RoomDatabase,String[],Callable<T>)

我试图弄清楚如何在房间里使用rxjava，我遵循了示例，但它抛出了一个错误，问题是什么？Completable很好用
