我在MainDao中有一个问题。类：

• 无法解析符号'notes_table'
• 无法解析符号'id'
• 无法解析符号'notes_table'
• 无法解析符号'title'
• 无法解析符号'description'

"我该如何解决这个问题"
我的代码：
第一千一百一十一章等级大道

@Dao
public interface MainDao{
    @Insert(onConflict = REPLACE)
    void insert(Notes notes);

    @Query("SELECT * FROM notes_table ORDER BY id DESC")
    List<Notes> getAll();

    @Query("Update notes_table SET title = :title, description = :description where id = :id")
    void update(int id, String title, String description);

      @Delete
void delete(Notes notes);}

RoomDB.java

@Database(entities = Notes.class, version = 1, exportSchema = false)

   @Dao
    public abstract class RoomDB extends RoomDatabase {
    private static RoomDB database;
    private static String DATABASE_NAME = "NoteApp";

    public synchronized static RoomDB getInstance(Context context) {
        if (database == null) {
            database = Room.databaseBuilder(context.getApplicationContext(), RoomDB.class, DATABASE_NAME)
                    .allowMainThreadQueries()
                    .fallbackToDestructiveMigration()
                    .build();
        }
        return database;
    }

    public abstract MainDao MainDao();
}

Notes.java

@Entity(tableName = "notes_table")
public class Notes implements Serializable {

    @PrimaryKey(autoGenerate = true)
    int id = 0;

    @ColumnInfo(name = "title")
    String title = "";

    @ColumnInfo(name = "description")
    String description = "";

    @ColumnInfo(name = "date")
    String date = "";
}
