可以自定义树的映射字段吗?

主键为Id，但是父子级关联的不是Id。请问怎么配置树查询？
public class BomInfo{
[JsonProperty, Column(IsPrimary = true)]
public long Id {get;set;}

/// <summary>
/// Bom编号
/// </summary>
[JsonProperty, Column(DbType = "varchar(500)", IsNullable = false)]
public string BomCode { get; set; }

/// <summary>
/// 上级Bom编号
/// </summary>
[JsonProperty, Column(DbType = "varchar(500)")]
public string ParentCode { get; set; }

[Navigate(nameof(ParentCode))]
public BomInfo? Parent { get; set; }

[Navigate(nameof(ParentCode))]
public List<BomInfo> Childs { get; set; } = new List<BomInfo>();

}

已经找到解决方式了.
[Navigate(nameof(ParentCode), TempPrimary = nameof(BomCode))]
public BomInfo? Parent { get; set; }

[Navigate(nameof(ParentCode), TempPrimary = nameof(BomCode))]
public List Childs { get; set; } = new List();
