YZR MVC模式

简要:

      我有些朋友以为YZR框架只能在webform模式下玩,其实不是的,在mvc下照样能跑.

YZR MVC:

      MVC模式之中,Models模型,在这里我定义为Model实体层,不写业务逻辑.(有一部分开发人员会当成逻辑层写,实现一个"肥"的Models和一个"哑"的控制器).View视图这里不讲(Rzaor视图引擎我此前也有介绍过,感兴趣可以去了解了解),在Controller这块(具体的ActionResult,传值,还有机制这里也不多说,详细可以看回之前的相关随笔)我们讲一下框架MVC的AjaxController支持.

 

      在MVC中,Action就相当.ashx一般处理程序,框架提供的支持使用一个AjaxController.

1.面向切面编程

实现权限,登录等等逻辑重写过滤器

2.框架对新增,修改的集合支持

3.UI层的相关参数

4.提供Request操作

        #region Query<T>
        public T Query<T>(Enum key)
        {
            return Query<T>(key.ToString(), default(T));
        }

        public T Query<T>(string key)
        {
            return Query<T>(key, default(T));
        }

        public T Query<T>(string key, T defaultValue)
        {
            return WebHelper.Query<T>(key, defaultValue, false);
        } 
        #endregion

5.统一处理

        #region 统一处理
        /// <summary>
        /// 统一处理:读取界面列表json数据   ===>单表
        /// </summary>
        public virtual ActionResult GetList()
        {
            if (string.IsNullOrEmpty(TableName))
            {
                throw new Exception("需要传递表名");
            }
            IDataBase action = RUtility.Instance.GetDbUtility(TableName);
            int totalCount = 0;
            if (PageIndex < 1) throw new Exception("pageIndex参数不正确");
            //去掉前缀
            string orderField = Sort.Replace("JSON_", "");
            action.ROpen();
            DataTable dt = action.Select(getComBoxWhere, PageSize, PageIndex, orderField, Order, out  totalCount);
           
            action.RClose();
            string JsonStr = JsonHelper.CreateJsonParameters(dt, true, totalCount, "rows");
            jsonResult = JsonStr;
            return Content(jsonResult);
        }
        /// <summary>
        /// 统一处理:编辑
        /// </summary>
        public virtual ActionResult Update()
        {
            IDataBase action = RUtility.Instance.GetDbUtility(TableName);
            int blResult = 0;
            
            string writeMsg = "操作失败！";
            TableNames result;
            if (Enum.TryParse<TableNames>(TableName, out result))
            {
                SetRDic(result);
            }
            else
            {
                throw new Exception("tablename异常");
            }
            
            action.ROpen();
            blResult = action.Update(dic, PKey, true);
            action.RClose();
            if (blResult > 0)
            {
                writeMsg = "更新成功!";
            }
            else
            {
                writeMsg = "更新失败!";
            }
            jsonResult = writeMsg;
            return Content(jsonResult);
        }
        /// <summary>
        /// 统一处理:查询一条数据
        /// </summary>
        public virtual ActionResult SelectOne()
        {
            //IDataBase action = new RAction("SYS_ADMIN");
            IDataBase action = RUtility.Instance.GetDbUtility(TableName);
            int id = GetID != "" ? Convert.ToInt32(GetID) : 0;
            List<DbParam> list = new List<DbParam>();
            action.ROpen();
            DataTable dt = action.SelectOne(" " + PKey + "=" + id, list);
            action.RClose();
            string writeMsg = "操作失败！";
            if (dt.Rows.Count > 0)
            {
                jsonResult = JsonHelper.CreateJsonOne(dt, null);
            }
            else
                jsonResult = writeMsg;
            return Content(jsonResult);
        }
        /// <summary>
        /// 统一处理:删除数据
        /// </summary>
        public virtual ActionResult Delete()
        {
            IDataBase action = RUtility.Instance.GetDbUtility(TableName);
            string id = GetID != "" ? GetID : null;
            string writeMsg = "操作失败！";
            int blResult;
            if (!string.IsNullOrEmpty(id))
            {
                action.ROpen();
                blResult = action.Remove(id, PKey);
                action.RClose();
                if (blResult > 0)
                {
                    writeMsg = "删除成功";
                }
            }
            jsonResult = writeMsg;
            return Content(jsonResult);
        }
        /// <summary>
        /// 统一处理:增加数据
        /// </summary>
        public virtual ActionResult Add()
        {
            IDataBase action = RUtility.Instance.GetDbUtility(TableName);
            int blResult = 0;

            string writeMsg = "操作失败！";
            TableNames result;

            if (Enum.TryParse<TableNames>(TableName, out result))
            {
                SetRDic(result);
            }
            action.ROpen();
            blResult = action.Insert(dic);
            action.RClose();
            if (blResult > 0)
            {
                writeMsg = "增加成功!";
            }
            else
            {
                writeMsg = "增加失败!";
            }
            jsonResult = writeMsg;
            return Content(jsonResult);
        }

        public virtual ActionResult Submit()
        {
            return Content(jsonResult);
        }
        
        #endregion

6.辅助方法

        public void SetKeyValue(Enum key, string value)
        {
            SetKeyValue(key.ToString(), value);
        }

        public void SetKeyValue(string key, string value)
        {
            if (!keyValue.ContainsKey(key))
            {
                //加入字典集合
                keyValue.Add(key, value);
            }
        } 

7.在UI层的Controller

    /// <summary>
    /// 框架Controll类
    /// </summary>
    public partial class HomeController : AjaxControll
    {
        //
        // GET: /Home/

        public HomeController()
        { 
            SysLogic sysLogic;
            sysLogic = new SysLogic(this);
        }
        
    }

写相关逻辑代码的地方:

    public partial class HomeController
    {
        public ActionResult Index()
        {
            return View();
        }
        public override ActionResult GetList()
        {
            //处理多表,视图操作
            switch (ObjName)
            {
                default:
                    return base.GetList();
            }
        }
        public override ActionResult Submit()
        {
            //处理多表,视图操作
            switch (ObjName)
            {
                default:
                   return  base.Submit();
            }
        }
        public override ActionResult Add()
        {
            //处理多表,视图操作
            switch (ObjName)
            {
                default:
                    return base.Add();
                    break;
            }
        }
        public override ActionResult Update()
        {
            //处理多表,视图操作
            switch (ObjName)
            {
                default:
                    return base.Update();
                    break;
            }
        }
        public override ActionResult SelectOne()
        {
            //处理多表,视图操作
            switch (ObjName)
            {
               
                default:
                    return base.SelectOne();
                    break;
            }
        }
        public override ActionResult Delete()
        {
            switch (ObjName)
            {
                
                default:
                    return base.Delete();
                    break;
            }
        }
    }

 

 

YZR框架是能够在MVC模式下跑起来的,YZR框架提供的封装能够在YZR MVC下使用(比如RPo,RTranscation)之外,在asp.net mvc下的技术也是能够在YZR MVC运行的.
