如何使用Room获取相关数据

Question

@Entity
data class User(
    @PrimaryKey
    val id: Int,
    val petsId: List<String>
)

@Entity
data class Pet(
    @PrimaryKey
    val id: Int,
    val name: String
)

如何使用Room从两个User和Pet实体获取UserWithPets？

data class UserWithPets(
    val id: Int,
    val pets: List<Pet>
)
