温馨提示：小编为您整理了“利用ASP.NET MVC+EasyUI+SqlServer搭建企业开发框架”,方便广大网友查阅！

本文主要介绍使用asp.net mvc4、sqlserver、jquery2.0和easyui1.4.5搭建企业级开发框架的过程，希望能够帮到大家。

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：

<thead>

<tr>

customerId

</th>

companyName

</th>

phone

</th>

address

</th>

</tr>

</thead>

</table>

<div>

</div>

<div>

<input id="queryBox" class="easyui-textbox" buttonicon="icon-search" style="width: 200px;"

data-options="onClickButton:function(){loadList(loadListSettings);}" />

详细查询</a>

</div>

var loadListSettings = { searchFields: "customerId,companyName", prompt: "请输入客户Id或公司名称" };

</script>

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>

@RenderSection("scripts", required: false)

</head>

@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：

1、Controller基类BaseController：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Web.Mvc;

using System.Data.Entity;

using System.Data.SqlClient;

using System.Data.Entity.Validation;

using System.ComponentModel;

using System.Reflection;

using System.Web.Security;

using formula;

namespace formula

{

public abstract class BaseController : Controller

{

#region 处理不存在的Action

protected override void HandleUnknownAction(string actionName)

{

if (Request.HttpMethod == "POST")

{

HttpContext.ClearError();

HttpContext.Response.Clear();

HttpContext.Response.StatusCode = 500;

HttpContext.Response.Write("没有Action:" + actionName);

HttpContext.Response.End();

}

// 搜索文件是否存在

var filePath = "";

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

protected override JsonResult Json(object data, string contentType, Encoding contentEncoding, JsonRequestBehavior behavior)

{

return result;

}

protected override JsonResult Json(object data, string contentType, Encoding contentEncoding)

{

NewtonJsonResult result = new NewtonJsonResult() { Data = data, ContentType = contentType, ContentEncoding = contentEncoding };

return result;

}

#endregion

#region 异常处理

{

var response = filterContext.RequestContext.HttpContext.Response;

response.Clear();

response.Write(exp.Message);

using System.Linq;

using System.Text;

using System.Collections;

using System.Web.Mvc;

namespace formula

{

[ModelBinder(typeof(QueryBuilderBinder))]

public class QueryBuilder : SearchCondition

}

if (hasOrderBy && str != "")

str = "order by " + str;

return str.Trim(',');

}

public class SearchCondition

{

public string fields = "*";

private List<ConditionItem> quickItems = new List<ConditionItem>();

private List<ConditionItem> complexItems = new List<ConditionItem>();

public SearchCondition add(string field, string method, object val, bool isQuickSearch = false)

{

//处理日期型数据

if (method == "<" || method == "<=")

{

if (val.GetType() == typeof(DateTime))

{

DateTime t = (DateTime)val;

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

}

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

if (isQuickSearch)

quickItems.Add(item);

else

complexItems.Add(item);

return this;

}

public string getWhereString(bool hasWhere = true)

{

if (quickItems.Count == 0 && complexItems.Count == 0)

return "";

string strWhere = "";

if (quickItems.Count > 0)

strWhere += " and (" + getGourpWhereString(quickItems, true) + ")";

if (complexItems.Count > 0)

strWhere += " and (" + getGourpWhereString(complexItems, false) + ")";

if (hasWhere)

strWhere = " where " + strWhere.Substring(4);

else

strWhere = " and " + strWhere.Substring(4);

return strWhere;

}

#region 私有方法

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

{

if (list.Count == 0)

return "";

string strWhere = "";

return strWhere;

}

#endregion

}

public class ConditionItem

{

public ConditionItem(string field, string method, object val)

{

this.field = field;

this.method = method;

this.value = val;

}

public string field { get; set; }

public string method { get; set; }

public object value { get; set; }

public string getWhereString()

{

var item = this;

switch (item.method)

{

case "=":

case "<":

case ">":

case "<=":

case ">=":

case "<>":

return string.Format("{0} {1} '{2}'", item.field, item.method, item.value);

case "in":

case "endWith":

return string.Format("{0} like '%{1}'", item.field, item.value);

default:

return "";

}

3、查询构造器QueryBuilder的创建方法QueryBuilderBinder：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Web.Mvc;

namespace formula

{

public class QueryBuilderBinder : IModelBinder

{

public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)

{

var qb = (QueryBuilder)(bindingContext.Model ?? new QueryBuilder());

var dict = controllerContext.HttpContext.Request.Params;

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

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";

return qb;

}

4、数据库查询帮助类SqlHelper：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Data.SqlClient;

using System.Data;

using System.Web;

namespace formula

{

public class SqlHelper

{

#region 构造函数

public SqlHelper(string connName)

{

if (System.Configuration.ConfigurationManager.ConnectionStrings[connName] == null)

throw new BuessinessException(string.Format("配置文件中不包含数据库连接字符串：{0}", connName));

this.connName = connName;

this.connString = System.Configuration.ConfigurationManager.ConnectionStrings[connName].ConnectionString;

}

public string connName { get; private set; }

public string connString { get; private set; }

public string dbName

{

get

{

SqlConnection conn = new SqlConnection(connString);

return conn.Database;

}

#endregion

#region 基本方法

public object ExecuteScalar(string cmdText)

{

using (SqlConnection conn = new SqlConnection(connString))

{

conn.Open();

SqlCommand cmd = new SqlCommand(cmdText, conn);

return cmd.ExecuteScalar();

}

public DataTable ExecuteDataTable(string cmdText)

{

using (SqlConnection conn = new SqlConnection(connString))

{

DataTable dt = new DataTable();

SqlDataAdapter apt = new SqlDataAdapter(cmdText, conn);

apt.Fill(dt);

return dt;

}

public DataTable ExecuteDataTable(string cmdText, int start, int len)

{

using (SqlConnection conn = new SqlConnection(connString))

{

DataTable dt = new DataTable();

SqlDataAdapter apt = new SqlDataAdapter(cmdText, conn);

apt.Fill(start, len, dt);

return dt;

}

public string ExecuteNonQuery(string cmdText)

{

using (SqlConnection conn = new SqlConnection(connString))

{

conn.Open();

SqlCommand cmd = new SqlCommand(cmdText, conn);

return cmd.ExecuteNonQuery().ToString();

}

#endregion

#region 支持查询对象

public DataTable ExecuteDataTable(string sql, SearchCondition cnd, string orderBy)

{

string sqlWhere = " where 1=1" + GetUrlFilterSqlWhere(sql) + cnd.getWhereString(false);

sql = string.Format("select {0} from ({1}) sourceTable {2} {3}", cnd.fields, sql, sqlWhere, orderBy);

DataTable dt = this.ExecuteDataTable(sql);

return dt;

}

public Dictionary<string, object> ExecuteGridData(string sql, QueryBuilder qb)

{

string sqlWhere = " where 1=1" + GetUrlFilterSqlWhere(sql) + qb.getWhereString(false);

qb.total = (int)this.ExecuteScalar(string.Format("select count(1) from ({0}) sourceTable {1}", sql, sqlWhere));

DataTable dt = ExecuteDataTable(sql, (qb.page - 1) * qb.rows, qb.rows);

Dictionary<string, object> dic = new Dictionary<string, object>();

dic.Add("total", qb.total);

dic.Add("rows", dt);

return dic;

}

#endregion

#region 私有方法

private string GetUrlFilterSqlWhere(string sql)

{

sql = string.Format("select * from({0}) as dt1 where 1=2", sql);

var dtField = ExecuteDataTable(sql);

StringBuilder sb = new StringBuilder();

foreach (string key in HttpContext.Current.Request.QueryString.Keys)

{

if (string.IsNullOrEmpty(key) || key.ToLower() == "id")

continue;

if (dtField.Columns.Contains(key))

{

string value = HttpContext.Current.Server.UrlDecode(HttpContext.Current.Request[key]);

value = value.Replace(",", "','");

sb.AppendFormat(" and {0} in ('{1}')", key, value);

}

return sb.ToString();

}

#endregion

}

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;

namespace formula

{

public static class JsonHelper

{

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)

{

}
