.NET ORM框架HiSql实战-第二章-使用Hisql实现菜单管理(增删改查)
一、引言
上一篇.NET ORM框架HiSql实战-第一章-集成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。
