.NET使用Hisql实现菜单管理(增删改查)

一、引言

上一篇.NET集成ORM框架HiSql 已经完成了Hisql的引入，本节就把 项目中的菜单管理改成hisql的方式实现。
菜单管理界面如图：

二、修改增删改查相关代码

1、 在 BaseRepository 仓储基类中添加 hisql访问对象：HiSqlClient。这样 所有继承了BaseRepository的业务仓储类都可以使用HiSqlClient操作数据库。本节中的菜单管理用到的仓储对象就是：SysMenuRepository

2、修改 SysMenuRepository类中访问数据的代码，将所有操作数据库的地方使用HiSql方式实现。

3、查询业务：获取菜单详情

        /// <summary>
        /// 获取菜单详情
        /// </summary>
        /// <param name="menuId"></param>
        /// <returns></returns>
        public SysMenu SelectMenuById(int menuId)
        {
            //hisql方式
            return ContextHiSql.HiSql(@"select * from sys_menu where menuId = @menuId ", new { menuId = menuId })
               .ToList<SysMenu>().FirstOrDefault();
            //sqlsuar方式
            return Context.Queryable<SysMenu>().Where(it => it.menuId == menuId).Single();
        }

4、修改业务：编辑菜单

        /// <summary>
        /// 编辑菜单
        /// </summary>
        /// <param name="menu"></param>
        /// <returns></returns>
        public int EditMenu(SysMenu menu)
        {

            //hisql方式
            return ContextHiSql.Update("sys_menu", menu).ExecCommand();
            //sqlsugar方式
            return Context.Updateable(menu).ExecuteCommand();
        }

5、删除业务：删除菜单

        /// <summary>
        /// 删除菜单
        /// </summary>
        /// <param name="menuId"></param>
        /// <returns></returns>
        public int DeleteMenuById(long menuId)
        {
            //hisql方式
            return ContextHiSql.Delete("sys_menu").Where(new Filter { { "menuId", OperType.EQ, menuId } }).ExecCommand();

            //sqlsugar方式
            return Context.Deleteable<SysMenu>().Where(it => it.menuId == menuId).ExecuteCommand();
        }

6、新增业务：添加菜单

        /// <summary>
        /// 添加菜单
        /// </summary>
        /// <param name="menu"></param>
        /// <returns></returns>
        public int AddMenu(SysMenu menu)
        {
            var Db = Context;
            menu.Create_time = Db.GetDate();

            menu.menuId = IDHelper.GetLongId();
            //hisql方式
            return ContextHiSql.Insert("sys_menu", menu).ExecCommand();

            //sqlsugar方式
            return Db.Insertable(menu).ExecuteCommand();
        }

Tip:此处使用雪花ID，其实HiSql自带相关方法。如 HiSql.Snowflake.NextId(); 以及业务根据业务实际情况自定义编号的模块，后面再集成到项目中来。 自定义编号

其他业务方法见 SysMenuRepository 代码。
