如何使用Android Room Persistence Library实现多对多关系？

// 实体类A
@Entity
public class EntityA {
    @PrimaryKey
    public int id;
    public String name;
}

// 实体类B
@Entity
public class EntityB {
    @PrimaryKey
    public int id;
    public String name;
}

// 中间实体类AB
@Entity(primaryKeys = {"entityAId", "entityBId"})
public class EntityAB {
    public int entityAId;
    public int entityBId;
}

// DAO接口
@Dao
public interface MyDao {
    @Insert
    void insertAB(EntityAB entityAB);

    @Transaction
    @Query("SELECT * FROM EntityA")
    List<EntityA> getEntityAWithBs();
}

// 数据库类
@Database(entities = {EntityA.class, EntityB.class, EntityAB.class}, version = 1)
public abstract class MyDatabase extends RoomDatabase {
    public abstract MyDao myDao();
}

// 使用示例
MyDatabase database = Room.databaseBuilder(context, MyDatabase.class, "my-database").build();
MyDao dao = database.myDao();

// 插入数据
EntityA entityA = new EntityA();
entityA.id = 1;
entityA.name = "EntityA1";
dao.insertA(entityA);

EntityB entityB = new EntityB();
entityB.id = 1;
entityB.name = "EntityB1";
dao.insertB(entityB);

EntityAB entityAB = new EntityAB();
entityAB.entityAId = 1;
entityAB.entityBId = 1;
dao.insertAB(entityAB);

// 查询数据
List<EntityA> entityAWithBs = dao.getEntityAWithBs();
