Room Dao 无法访问 Android 项目中的表名

Question

我的道

        @Dao
        public interface DrugDao {
            @Query("SELECT * FROM drugs")
            List<Drug> getDrugList();
            @Insert
            void insertDrug(Drug drug);
            @Update
            void updateDrug(Drug drug);
            @Delete
            void deleteDrug(Drug drug);
        }

我的实体

        @Entity(tableName = "drugs")
        public class Drug {
            @PrimaryKey(autoGenerate = true)
            private int id;
            @ColumnInfo(name = "name")
            private String name;
            @ColumnInfo(name = "dose")
            private int dose;
            @ColumnInfo(name = "frequency")
            private String frequency;
            @ColumnInfo(name = "checkBoxId")
            private String checkBoxId;
            @ColumnInfo(name = "checkBoxStatus")
            private boolean checked;

数据库类

    @Database(entities = Drug.class, exportSchema = false, version = 1)
    public abstract class DrugDatabase extends RoomDatabase {
        private static final String DB_NAME= "drug_db";
        private static DrugDatabase instance;
    
        public static synchronized DrugDatabase getInstance(Context context) {
            if (instance == null) {
                instance = Room.databaseBuilder(context.getApplicationContext(), DrugDatabase.class, DB_NAME)
                        .fallbackToDestructiveMigration()
                        .build();
            }
            return instance;
        }
    
        public abstract DrugDao drugDao();
    }

我这里有两个类，一个是道，一个是对象。目标是将对象存储在数据库中。由于某种原因，Dao @Query 无法访问对象中定义的表名。我在“药物”上收到错误，因为无法解析符号“药物”。

你能解决这个问题吗？我也遇到了同样的问题。
