路由数据获取及封装方法
数据库设计
自联表
定义tree字段
public class LabelValue{public int label { get; set; }public string? value { get; set; }public List<LabelValue> children { get; set; }}
获取路由方法
public Response<object> getMenuList()
{Response<object> result = new Response<object>();//一级菜单List<Menu> Menu_level1_list = db.Queryable<Menu>().Where(t => t.parent_id == 0).ToList();List<LabelValue> LabelValueList1 = new List<LabelValue>();foreach (var menu1 in Menu_level1_list){var labelValue1 = new LabelValue{label = menu1.ID,value = menu1.Name,children = BuildMenuTree(menu1.ID)};LabelValueList1.Add(labelValue1);}result.Data = LabelValueList1;return result;
}
路由递归函数
public List<LabelValue> BuildMenuTree(int? parentId = null){SqlSugarClient db = SqlsugarSetup.db;var menuList = db.Queryable<Menu>().Where(t => t.parent_id == parentId).ToList();var labelValueList = new List<LabelValue>();foreach (var menu in menuList){var labelValue = new LabelValue{label = menu.ID,value = menu.Name,children = BuildMenuTree(menu.ID) };labelValueList.Add(labelValue);}return labelValueList;}
