利用ASP.NET MVC+EasyUI+SqlServer搭建企业开发框架_实用技巧

我们要搭建的框架是企业级开发框架，适用用企业管理信息系统的开发，如：OA、HR等

1、框架名称：sampleFrame。

2、搭建原则：最少知识原则。

3、先定义一个简单的编码规范：除类名和接口名外，其余首字母小写。

4、准备开发环境：vs2010及以上（mvc4）、sqlserver、jquery2.0和easyui1.4.5

首先来看一下列表页面的效果图：

我们期望简洁带前台代码，如下：

<table id="dataGrid" class="easyui-datagrid" url="getList" toolbar="#toolbar">
 <thead>
 <tr>
  <th field="customerId" sortable="true" data-options="sortable:true" width="50">
  customerId
  </th>
  <th field="companyName" data-options="sortable:true" width="50">
  companyName
  </th>
  <th field="phone" width="50">
  phone
  </th>
  <th field="address" width="50">
  address
  </th>
 </tr>
 </thead>
</table>
<div id="toolbar">
 <div>
 <a class="easyui-linkbutton" iconcls="icon-add" onclick="add();">添加</a>
 <a class="easyui-linkbutton" iconcls="icon-edit" onclick="edit();">修改</a>
 <a class="easyui-linkbutton" iconcls="icon-remove" onclick="del();">删除</a>
 </div>
 <div>
 <input id="queryBox" class="easyui-textbox" buttonicon="icon-search" style="width: 200px;"
  data-options="onClickButton:function(){loadList(loadListSettings);}" />
 <a class="easyui-linkbutton" iconcls="icon-find" onclick="showQueryWindow();">
  详细查询</a>
 </div>
</div>
<script type="text/javascript">
 var loadListSettings = { searchFields: "customerId,companyName", prompt: "请输入客户Id或公司名称" };
</script>
<script type="text/javascript">
 pageInit();
</script>

为了这样简洁的前台，我们需要准备：

1、通用的布局模板_Layout.cshtml。base.css、base.js、defaultSettings.js、tool.js和private.js见后面

<!doctype html>
<html>
<head>
 <meta charset="utf-8" />
 <meta name="viewport" content="width=device-width" />
 <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1" />
 <link href='/webResource/easyui/themes/default/easyui.css' rel='stylesheet' type='text/css' />
 <link href='/webResource/easyui/themes/icon.css' rel='stylesheet' type='text/css' />
 <link href='/webResource/base.css' rel='stylesheet' type='text/css' />
 <script src="/webResource/jquery/jquery.min.js" type="text/javascript"></script>
 <script src="/webResource/jquery/json2.js" type="text/javascript"></script>
 <script src="/webResource/easyui/jquery.easyui.min.js" type="text/javascript"></script>
 <script src="/webResource/easyui/locale/easyui-lang-zh_CN.js" type="text/javascript"></script>
 <script src="/webResource/tool.js" type="text/javascript"></script>
 <script src="/webResource/base.js" type="text/javascript"></script>
 <script src="/webResource/defaultSettings.js" type="text/javascript"></script>
 <script src="/webResource/private.js" type="text/javascript"></script>
 @RenderSection("scripts", required: false)
</head>
<body style="width: 100%; height: 100%; margin: 0px;">
 @RenderBody()
</body>
</html>

2、平台样式表base.css

.icon-find
{
 background: url('icons/find.png') no-repeat center center;
}

.datagrid-toolbar div:nth-child(1)
{
 float: left;
 width: 60%;
}
.datagrid-toolbar div:nth-child(2)
{
 margin-left: 60%;
 margin-right: 10px;
 width: auto;
 text-align: right;
}

3、基本方法脚本base.js

//取消自动渲染
$.parser.auto = false;

function pageInit() {

 //改变控件默认值
 $.fn.linkbutton.defaults.plain = true;
 $.fn.datagrid.defaults.fit = true;
 $.fn.datagrid.defaults.fitColumns = true;
 $.fn.datagrid.defaults.pagination = true;

 //显示ajax异常信息
 $(document).ajaxError(function (event, xhr, options, exc) {
 $.messager.alert({ title: '异步请求出错', msg: xhr.responseText, icon: "error" });
 });

 //地址栏传参允许中文
 jQuery(document).ajaxSend(function (event, request, options) {
 options.url = encodeURI(options.url);
 });

 $.parser.parse();
}

function loadList(settings) {
 var settings = $.extend(true, {}, loadListDefaultSettings, settings);

 if ($("#" + settings.gridId).length == 0)
 $.messager.alert({ title: "系统异常", msg: "DataGrid：" + settings.gridId + "不存在！", icon: "error" });

 var quickQueryData = [];
 if ($("#" + settings.queryBoxId).length > 0) {
 var val = $("#" + settings.queryBoxId).textbox("getValue");
 if (settings.searchFields && val) {
  var keys = settings.searchFields.split(',');
  for (i = 0, len = keys.length; i < len; i++) {
  quickQueryData.push({ field: keys[i], method: 'inLike', value: val });
  }
 }
 }

 var queryData = []; //详细查询预留 

 //加载数据
 $("#" + settings.gridId).datagrid("load", { quickQueryData: JSON.stringify(quickQueryData), queryData: JSON.stringify(queryData) });
}

4、基本脚本默认值defaultSettings.js

//查询参数设置
var loadListDefaultSettings = {
 url: "getList",
 gridId: "dataGrid",
 queryWindowId: "queryWindow",
 queryBoxId: "queryBox",
 searchFields: "Name",
 addQueryString: true,
 prompt: "请输入"
};

5、可能需要使用的工具方法tool.js

//判断是否包含地址栏参数
function hasQueryString(key, url) {
 if (typeof (url) == "undefined")
 url = window.location.search;

 var re = new RegExp("[?&]" + key + "=([^\\&]*)", "i");
 var a = re.exec(url);
 if (a == null) return false;
 return true;
}

//获取地址栏参数,如果参数不存在则返回空字符串
function getQueryString(key, url) {
 if (typeof (url) == "undefined")
 url = window.location.search;
 var re = new RegExp("[?&]" + key + "=([^\\&]*)", "i");
 var a = re.exec(url);
 if (a == null) return "";
 return a[1];
}

//将当前地址栏参数加入到url
function addUrlSearch(url) {
 var newParams = [];

 var paramKeys = window.location.search.replace('?', '').split('&');
 for (var i = 0; i < paramKeys.length; i++) {
 var key = paramKeys[i].split('=')[0];
 if (key == "" || key == "_t" || key == "_winid" || key == "isTab")
  continue;
 if (!hasQueryString(key, url))
  newParams.push(paramKeys[i]);
 }

 if (url.indexOf('?') >= 0)
 return url + "&" + newParams.join('&');
 else
 return url + "?" + newParams.join('&');
}

//url增加参数
function addSearch(url, key, value) {
 if (!hasQueryString(key, url)) {
 if (url.indexOf('?') >= 0)
  return url + "&" + key + "=" + value;
 else
  return url + "?" + key + "=" + value;
 }
 else
 return url;
}

//获取数组中对象的某个值，逗号分隔
function getValues(rows, attr) {
 var fieldValues = [];
 for (var i = 0; i < rows.length; i++) {
 if (rows[i] != null)
  fieldValues.push(rows[i][attr]);
 }
 return fieldValues.join(',');
}

6、可能需要使用的私有方法private.js，此文件包含的方法专供base.js使用，开发web时禁止使用

//替换掉Url中的{}参数
function replaceUrl(settings, pty) {
 if (!pty)
 pty = "url";
 if (!settings[pty])
 return;
 var str = settings[pty];
 var guid = "";
 var result = str.replace(/\{[0-9a-zA-Z_]*\}/g, function (e) {
 var key = e.substring(1, e.length - 1);

 if (key == "GUID") {
  if (!guid) {
  $.ajax({
   url: "getGuid",
   type: "post",
   async: false,
   success: function (text, textStatus) {
   guid = text;
   }
  });
  }
  return guid;
 }
 if (hasQueryString(key)) //从地址栏返回
  return getQueryString(key);
 if (settings.currentRow && settings.currentRow[key])//从当前行返回
  return settings.currentRow[key];
 if (settings.paramFrom) { //从指定控件返回
  var ctrl = mini.get(settings.paramFrom);
  if (ctrl == undefined) {
  $.messager.alert({ title: 'UI出错', msg: "Id为" + settings.paramFrom + "的控件不存在！", icon: "error" });
  return;
  }
  else if (ctrl.showCheckBox) {
  return getValues(ctrl.getCheckedNodes(), key);
  }
  else if (ctrl.getSelecteds)
  return getValues(ctrl.getSelecteds(), key);
  else if (ctrl.getValue)
  return ctrl.getValue();
 }

 return e;
 });

 settings[pty] = result;
 return result;
}

//转化为全路径
function changeToFullUrl(settings) {
 var url = settings.url;
 if (url.indexOf('/') == 0 || url.indexOf("http://") == 0 || url.indexOf('?') == 0 || url == "")
 return url;

 currentUrlPathName = window.location.pathname;

 var currentPathNameParts = currentUrlPathName.split('/');
 var pathNameParts = url.split('?')[0].split('/');
 if (currentPathNameParts[currentPathNameParts.length - 1] == "")
 currentPathNameParts.pop(); //去掉一个反斜线
 if (pathNameParts[pathNameParts.length - 1] == "")
 pathNameParts.pop(); //去掉一个反斜线

 var index = currentPathNameParts.length - 1;

 for (var i = 0; i < pathNameParts.length; i++) {
 if (pathNameParts[i] == "..") {
  index = index - 1;
  if (index <= 0) {
  $.messager.alert({ title: "系统异常", msg: "Url错误：" + url + "！", icon: "error" });
return;
  }
  continue;
 }

 if (index < currentPathNameParts.length)
  currentPathNameParts[index] = pathNameParts[i];
 else
  currentPathNameParts.push(pathNameParts[i]);
 index = index + 1;
 }
 var length = currentPathNameParts.length;
 for (var i = index; i < length; i++) {
 currentPathNameParts.pop();
 }

 var result = currentPathNameParts.join('/');

 if (url.indexOf('?') > 0)
 result += url.substring(url.indexOf('?'));

 settings.url = result;
}

我们期望简洁的后台代码，如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using formula;
using System.Data;

namespace demo.Areas.basic.Controllers
{
 public class customerController : BaseController
 {
 public JsonResult getList(QueryBuilder qb)
 {
  SqlHelper sqlHelper = new SqlHelper("demo");
  var data = sqlHelper.ExecuteGridData("select *,id=customerId from customer", qb);
  return Json(data);
 }
 }
}

为了这种简洁的代码我们需要：

  HttpContext.Response.End();
  }

  // 搜索文件是否存在

  if (RouteData.DataTokens["area"] != null)
  filePath = string.Format("~/Areas/{2}/Views/{1}/{0}.cshtml", actionName, RouteData.Values["controller"], RouteData.DataTokens["area"]);
  else
  filePath = string.Format("~/Views/{1}/{0}.cshtml", actionName, RouteData.Values["controller"]);
  if (System.IO.File.Exists(Server.MapPath(filePath)))
  {
  View(filePath).ExecuteResult(ControllerContext);
  }
  else

  HttpContext.ClearError();
  HttpContext.Response.Clear();
  HttpContext.Response.StatusCode = 500;
  HttpContext.Response.Write("没有Action:" + actionName);
  HttpContext.Response.End();
  }
 }
 #endregion

 #region 基类Json方法重载

using System.Collections;
using System.Web.Mvc;

namespace formula

   DateTime t = (DateTime)val;
   val = t.Date.AddHours(23).AddMinutes(59).AddSeconds(59);
  }
  }

  ConditionItem item = new ConditionItem(field, method, val);
  if (isQuickSearch)

  return strWhere;
 }

 #region 私有方法

 private string getGourpWhereString(List<ConditionItem> list, bool isOrRelation = false)
 {

  if (list.Count == 0)
  return "";

  string strWhere = "";
  for (int i = 0; i < list.Count(); i++)
  {
  var item = list[i];
  string str = item.getWhereString();

  if (isOrRelation)

   strWhere += " or " + str;
  }
  else

  }
  }

  strWhere = strWhere.Substring(4);

  return strWhere;
 }

 #endregion

 }

 public class ConditionItem

  var queryList = !string.IsNullOrEmpty(dict["queryData"]) ? JsonHelper.ToList(dict["queryData"]) : new List<Dictionary<string, object>>();

  foreach (var dic in quickQueryList)
  {
  var val = dic["value"].ToString();
  if (val == "") continue;
  qb.add(dic["field"].ToString(), dic["method"].ToString(), val, true);
  }

  foreach (var dic in queryList)
  {
  var val = dic["value"].ToString();
  if (val == "") continue;
  qb.add(dic["field"].ToString(), dic["method"].ToString(), val, false);
  } 

  qb.page = !string.IsNullOrEmpty(dict["page"]) ? int.Parse(dict["page"].ToString()) : 1;
  qb.rows = !string.IsNullOrEmpty(dict["rows"]) ? int.Parse(dict["rows"].ToString()) : 10;
  qb.sort = !string.IsNullOrEmpty(dict["sort"]) ? dict["page"].ToString() : "id";
  qb.order = !string.IsNullOrEmpty(dict["order"]) ? dict["order"].ToString() : "desc";

5、用于取代返回值JsonResult的NewtonJsonResult：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Mvc;
using System.Web;
using System.Data;

namespace formula
{
 public class NewtonJsonResult : JsonResult
 {
 public override void ExecuteResult(ControllerContext context)
 {
  //确认是否用于响应HTTP-Get请求
  if (this.JsonRequestBehavior == JsonRequestBehavior.DenyGet &&
  string.Compare(context.HttpContext.Request.HttpMethod, "GET", true) == 0)
  {
  throw new InvalidOperationException("禁止Get请求");
  }

  HttpResponseBase response = context.HttpContext.Response;
  //设置媒体类型和编码方式
  response.ContentType = string.IsNullOrEmpty(this.ContentType) ?
  "application/json" : this.ContentType;
  if (this.ContentEncoding != null)
  {
  response.ContentEncoding = this.ContentEncoding;
  }

  //序列化对象，并写入当前的HttpResponse
  if (null == this.Data) return;

  if (this.Data is string)
  {
  response.Write(Data);
  }
  else if (this.Data is DataRow)
  {
  Dictionary<string, object> dic = new Dictionary<string, object>();
  DataRow row = this.Data as DataRow;
  foreach (DataColumn col in row.Table.Columns)
  {
   dic.Add(col.ColumnName, row[col]);
  }
  response.Write(JsonHelper.ToJson(dic));
  }
  else
  {
  response.Write(JsonHelper.ToJson(this.Data));
  }
 }
 }

}

6、Json序列化和反序列的帮助类JsonHelper：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Newtonsoft.Json.Converters;
using Newtonsoft.Json;

 public static string ToJson<T>(T obj)
 {

  if (obj == null || obj.ToString() == "null") return null;

  if (obj != null && (obj.GetType() == typeof(String) || obj.GetType() == typeof(string)))
  {
  return obj.ToString();
  }

  IsoDateTimeConverter dt = new IsoDateTimeConverter();
  dt.DateTimeFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ss";
  return JsonConvert.SerializeObject(obj, dt);

 }

 /// <summary>
 /// 从一个Json串生成对象信息
 /// </summary>
 /// <param name="jsonString">JSON字符串</param>
 /// <typeparam name="T">对象类型</typeparam>
 /// <returns></returns>
 public static T ToObject<T>(string json) where T : class
 {
  if (String.IsNullOrEmpty(json)) return null;
  T obj = JsonConvert.DeserializeObject<T>(json);
  return obj;
 }

 /// <summary>
 /// 返回 Diction<string,object>
 /// </summary>
 /// <param name="json"></param>
 /// <returns></returns>
 public static Dictionary<string, object> ToObject(string json)
 {
  if (String.IsNullOrEmpty(json)) return new Dictionary<string, object>();
  return ToObject<Dictionary<string, object>>(json);
 }

 /// <summary>
 /// 返回 List<Dictionary<string, object>>
 /// </summary>
 /// <param name="json"></param>
 /// <returns></returns>
 public static List<Dictionary<string, object>> ToList(string json)
 {
  if (String.IsNullOrEmpty(json)) return new List<Dictionary<string, object>>();
  return ToObject<List<Dictionary<string, object>>>(json);
 }

 /// <summary>
 /// 组装对象
 /// </summary>
 /// <param name="json"></param>
 /// <param name="obj"></param>
 public static void PopulateObject(string json, object obj)
 {
  if (String.IsNullOrEmpty(json)) return;
  JsonConvert.PopulateObject(json, obj);
 }
 }
}

7、用于区分系统异常和业务异常的BusinessException：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;

namespace formula
{
 /// <summary>
 /// 业务异常
 /// </summary>
 [Serializable]
 public class BuessinessException : Exception
 {
 /// <summary>
 /// 系统异常构造函数
 /// </summary>
 public BuessinessException()
 {

 }

 /// <summary>
 /// 系统异常构造函数
 /// </summary>
 /// <param name="message">异常的消息</param>
 public BuessinessException(string message)
  : base(message)
 {

 }

 /// <summary>
 /// 系统异常构造函数
 /// </summary>
 /// <param name="message">异常的消息</param>
 /// <param name="inner">内部的异常</param>
 public BuessinessException(string message, System.Exception inner)
  : base(message, inner)
 {

 }

 /// <summary>
 /// 系统异常构造函数
 /// </summary>
 /// <param name="info">存有有关所引发异常的序列化的对象数据</param>
 /// <param name="context">包含有关源或目标的上下文信息</param>
 public BuessinessException(SerializationInfo info, StreamingContext context)
  : base(info, context)
 {

 }
 }
}

为ASP.NET MVC及WebApi添加路由优先级_实用技巧

一.为什么需要路由优先级 大家都知道我们在Asp.Net MVC项目或WebApi项目中注册路由是没有优先级的,当项目比较大.或有多个区域.或多个Web项目.或采用插件式框架开发时,我们的路由注册很可能 不是写在一个文件中的,而是分散在很多不同项目的文件中,这样一来,路由的优先级的问题就突显出来了. 比如: App_Start/RouteConfig.cs中 routes.MapRoute( name: "Default", url: "{controller}/{actio

ASP.NET MVC分页和排序功能实现_实用技巧

分页和排序,应该是软件开发中,需要必知必会的技能了,对于分页,网上很多教程,当然,别人终究是别人的,只有自己理解,会了,并且吸收之后,再用自己的语言,传授出来,这才是硬道理.好了,废话说多了.现在我们进入正题:  这里,我打算使用EF Code-First方式分页控件就是用PagedList.MVC,来做分页,对于排序,实现的思路是,加载数据出来之后,默认是升序排序,然后我们点击一下相应的列标题,就按照该字段降序排序,查数据.思路明确了,就开始干吧!  1.首先新建一个空白的MVC项目,在Mod
