继承了BaseExpandNode，无法重写isExpanded，

[sceneren]

因为我使用了room，定义了一个嵌套关系，所有无法在结果的实体类里去忽略isExpaned字段，导致room编译不过

    @Embedded val departDBInfo: DepartDBInfo,

    @Relation(parentColumn = "id", entityColumn = "parentId")
    val child: MutableList<DepartDBInfo>,
) : BaseExpandNode() {

    @Ignore
    override var childNode: MutableList<BaseNode> = mutableListOf<BaseNode>()

    fun getItemType(): Int {
        return departDBInfo.type
    }

}

编译报错 Non-existent columns are specified to be ignored in ignoreColumns: isExpanded public final class DepartDBInfo

在实体类中添加 @Entity(ignoredColumns = ["isExpand"])
