EFW框架源代碼下載：http://pan.baidu.com/s/1qWJjo3Ucss
EFW框架中的WebController就是解決JqueryEasyUI與邏輯層的交互，之間的數據是經過Json字符串來傳遞；值得注意的是WebController的代碼必定不要和EFWWeb項目放在一塊兒，你能夠單獨建一個項目類庫，也能夠和邏輯層項目放一塊兒；在EFWWeb項目不要編寫任何C#代碼，這個在前面的文章中就提過，可讓你的Web項目發佈更省事一點，免去編譯EFWWeb項目的痛苦；html
控制器能夠調用分層一下的全部代碼，包括ObjectModel、Dao、Entity，甚至能夠直接用oleDb編寫SQL語句操做數據庫；還有控制器與控制器之間是不能存在任何依賴關係的；java
本章主要內容經過解讀框架源代碼來學習WebController是怎麼實現的，以及思考這樣實現會給咱們開發帶來什麼好處；jquery

1.如何使用Web控制器
講解EFW框架中的Web控制器的使用以前先看看傳統的Web系統是如何開發的；
如上圖，傳統方式一個aspx文件對應一個cs文件，開發方式跟Winform桌面程序相同，都是事件響應的模式；咱們再看看EFW框架中是如何開放的；
如上圖，有兩個項目EFWWeb項目和Books項目，EFWWeb項目裏面只有界面HTML代碼和JS代碼，後臺CS代碼在另外的Books項目中；接着看裏面的詳細代碼，界面層是如何調用後臺的Web控制器的；

bookController.cs文件
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using EFWCoreLib.WebFrame.Controller; 6 using Books.Entity; 7 using Books.Dao; 8 using System.Data; 9 10 namespace Books.WebController 11 { 12 [WebController] 13 public class bookController : EFWCoreLib.WebFrame.Controller.AbstractJqueryController 14 { 15 [WebMethod] 16 public void SaveBook() 17 { 18 Book book = GetModel<Book>(); 19 book.save(); 20 TxtJson = ReturnSuccess("保存書籍成功！"); 21 } 22 [WebMethod] 23 public void SearchBook() 24 { 25 string schar = ParamsData["schar"]; 26 int flag = Convert.ToInt32(ParamsData["flag"]); 27 28 IBookDao bdao = NewDao<IBookDao>(); 29 DataTable dt = bdao.GetBooks(schar, flag); 30 TxtJson = ToGridJson(dt); 31 } 32 33 public void TestEntity() 34 { 35 //建立實體對象實例 36 Book book = NewObject<Book>(); 37 38 //1.根據id獲取一條記錄 39 book= book.getmodel(1) as Book; 40 41 //2.修改或者新增一條記錄 42 book.BookName = "人月神話"; 43 book.BuyPrice = 23; 44 book.BuyDate = Convert.ToDateTime("2014-01-01"); 45 book.save(); 46 47 //3.根據id刪除表數據 48 book.delete(1); 49 50 //4.獲取表全部記錄轉換爲List實體對象 51 List<Book> booklist = book.getlist<Book>(); 52 53 //5.獲取表全部記錄轉換爲DataTable 54 DataTable dt = book.gettable(); 55 } 56 } 57 }
咱們先說Book.aspx文件，裏面的代碼是基於JqueryEasyUI框架編寫的，實現了一個網格數據，上面有添加、修改工具欄按鈕，點擊按鈕彈出維護界面；這些代碼沒有什麼好講得，等你熟悉JqueryEasyUI的相關控件後，就能很快的開發各類複雜界面；咱們接着看Book.js腳本文件，是採用Jquery的方式編寫javascript腳本；
界面加載後就會執行這段代碼，實現網格的數據顯示，給datagrid控件設置url地址就會自動向後臺發送Ajax請求，請求返回的Json數據datagrid控件解析後顯示在界面；重點說一下這個url的參數意思，這是通日後臺控制器的橋樑；controller指定後臺控制器的名稱bookController，method指定控制器內的方法名SearchBook，注意名稱的大小寫別搞錯了；
總結一下，Ajax向後臺發送請求的URL必須採用Controller.aspx?controller=XXX&method=XXX這種格式，調試的時候控制器中打了斷點沒有進來，首先查看指定的控制器名稱和方法名稱是否正確；
2.Web控制器的設計思路
上文中舉的實例是利用JqueryEasyUI開發的，若是個人項目不想要JqueryEasyUI，用更專業的Extjs或其餘界面框架怎麼辦，EFW框架設計的時候充分的考慮到了這一點，咱們看最上的「EFW框架控制器設計圖」，bookController繼承的是AbstractJqueryController對象，AbstractJqueryController對象又繼承的AbstractController對象，AbstractController是Web控制器的核心基類，AbstractJqueryController就是針對JqueryEasyUI框架實現的控制器，咱們要實現Extjs框架，就只要想只要像AbstractJqueryController同樣編寫一個適合Extjs框架的控制器基類，咱們的bookController繼承它就好了；
還有好比咱們還開發手機上運行的網頁程序，一樣能夠用這種方式來實現，下一個版本會把jquery.mobile引入到EFW框架中；
3.Web控制器基類AbstractController的實現
這裏講解一下Web控制器的核心基類AbstractController的代碼實現；
AbstractController文件
1 public abstract class AbstractController:AbstractBusines 2 { 3 public AbstractDatabase oleDb 4 { 5 get 6 { 7 return _oleDb; 8 } 9 } 10 11 public SysLoginRight GetSysLoginRight 12 { 13 get 14 { 15 if (sessionData != null && sessionData.ContainsKey("RoleUser")) 16 { 17 return (SysLoginRight)sessionData["RoleUser"]; 18 } 19 else 20 { 21 return new SysLoginRight(); 22 } 23 } 24 } 25 26 public HttpContext context { get; set; } 27 28 private System.Collections.Generic.Dictionary<string, Object> _sessionData; 29 /// <summary> 30 /// Session數據傳入後臺 31 /// </summary> 32 public System.Collections.Generic.Dictionary<string, Object> sessionData 33 { 34 get 35 { 36 return _sessionData; 37 } 38 set 39 { 40 _sessionData = value; 41 } 42 } 43 44 private System.Collections.Generic.Dictionary<string, Object> _putOutData; 45 /// <summary> 46 /// 後臺傳出數據到Session數據 47 /// </summary> 48 public System.Collections.Generic.Dictionary<string, Object> PutOutData 49 { 50 get 51 { 52 return _putOutData; 53 } 54 set 55 { 56 _putOutData = value; 57 } 58 } 59 60 private List<string> _clearKey; 61 /// <summary> 62 /// 清除Session的數據 63 /// </summary> 64 public List<string> ClearKey 65 { 66 get { return _clearKey; } 67 set { _clearKey = value; } 68 } 69 70 private System.Collections.Generic.Dictionary<string, string> _paramsData; 71 /// <summary> 72 /// Url參數傳遞數據 73 /// </summary> 74 public System.Collections.Generic.Dictionary<string, string> ParamsData 75 { 76 get { return _paramsData; } 77 set { _paramsData = value; } 78 } 79 80 private System.Collections.Generic.Dictionary<string, string> _formData; 81 /// <summary> 82 /// Form提交的數據 83 /// </summary> 84 public System.Collections.Generic.Dictionary<string, string> FormData 85 { 86 get { return _formData; } 87 set { _formData = value; } 88 } 89 90 91 }
AbstractController基類封裝了三方面的內容：
1）數據庫操做對象，這個咱們以前第十章也講過爲何要在控制器開放oleDb，這也是爲了讓框架分層使用起來更靈活，且兼容性強；
2）系統登陸用戶信息SysLoginRight，此屬性封裝了用戶登陸後的姓名、部門、機構等信息；這樣在控制器中查詢當前登陸用戶的數據時候會很簡單；
3）網頁中的數據，如請求參數、Session數據、表單數據等；從界面傳進來的數據均可以從中獲取；
4.Web控制器的自定義標籤WebControllerAttribute和WebMethodAttribute
爲了能讓系統根據url中控制器名稱和方法名稱找到對應的代碼執行，就像Webservice服務同樣須要對Web控制器的類名和方法名上加上上面兩個自定義標籤；
WebControllerAttribute文件
1 [AttributeUsageAttribute(AttributeTargets.Class, Inherited = true, AllowMultiple = false)] 2 public class WebControllerAttribute : Attribute 3 { 4 string _memo; 5 public string Memo 6 { 7 get { return _memo; } 8 set { _memo = value; } 9 } 10 }
WebMethodAttribute文件
1 [AttributeUsageAttribute(AttributeTargets.Method, Inherited = true, AllowMultiple = false)] 2 public class WebMethodAttribute : Attribute 3 { 4 private string _openDBNames; 5 /// <summary> 6 /// 打開數據庫，中間用,號隔開 7 /// </summary> 8 public string OpenDBKeys 9 { 10 get { return _openDBNames; } 11 set { _openDBNames = value; } 12 } 13 14 string _memo; 15 public string Memo 16 { 17 get { return _memo; } 18 set { _memo = value; } 19 } 20 }
值得注意的就是，控制器的名稱在整個系統中不能重複，若是出現相同名稱的控制器，系統就可能沒法正確調用對應的控制器；
5.基於JqueryEasyUI封裝的Web控制器的實現
接下來說解一下基於JqueryEasyUI封裝的AbstractJqueryController的代碼是如何實現的；AbstractJqueryController類繼承了IToJqueryEasyUIJson接口，IToJqueryEasyUIJson接口就是提取出了把數據對象轉換爲符合JqueryEasyUI控件的Json字符串的方法；如：datagrid控件、Tree控件、treegrid控件等
IToJqueryEasyUIJson接口文件
1 /// <summary> 2 /// 對象轉與JqueryEasyUI匹配的Json格式 3 /// </summary> 4 public interface IToJqueryEasyUIJson 5 { 6 7 string TxtJson { get; set; } 8 string FilterJson(string json);//過濾json字符串中全部特殊字符 9 10 string ToJson(object model); 11 string ToJson(System.Data.DataTable dt);//轉json字符串，combobox控件用此方法 12 string ToJson(Hashtable hash); 13 14 string ToGridJson(string tojson, int totalCount); 15 string ToGridJson(string rowsjson, string footjson, int totalCount); 16 17 string ToGridJson(System.Data.DataTable dt); 18 string ToGridJson(System.Data.DataTable dt, int totalCount); 19 string ToGridJson(System.Data.DataTable dt, int totalCount, System.Collections.Hashtable[] footers); 20 21 22 string ToGridJson(System.Collections.IList list); 23 string ToGridJson(System.Collections.IList list, int totalCount); 24 string ToGridJson(System.Collections.IList list, int totalCount, System.Collections.Hashtable[] footers); 25 26 string ToFloorJson(List<floorclass> floor); 27 string ToFloorJson(List<floorclass> floor, int totalCount); 28 29 string ToTreeJson(List<treeNode> list); 30 31 string ToTreeGridJson(List<treeNodeGrid> list); 32 string ToTreeGridJson(List<treeNodeGrid> list, System.Collections.Hashtable[] footers); 33 string ToTreeGridJson(DataTable dt, string IdName, string _parentIdName); 34 string ToTreeGridJson(DataTable dt, string IdName, string _parentIdName, System.Collections.Hashtable[] footers); 35 string ToTreeGridJson(string rowsjson, string footjson, int totalCount); 36 37 T GetModel<T>();//從form表單提交的數據轉爲實體對象 38 T GetModel<T>(T model);//從form表單提交的數據賦值給model 39 40 41 DataTable ToDataTable(string json); 42 List<T> ToList<T>(string json); 43 44 string ReturnSuccess(); 45 string ReturnSuccess(string info); 46 string ReturnSuccess(string info, string data); 47 string ReturnError(string errmsg); 48 49 string ToView();//回退 50 string ToView(string info);//提示後再回退 51 string ToView(string info, string Url);//提示後調整到執行頁面 52 53 54 55 }
AbstractJqueryController文件
1 /// <summary> 2 /// 基於JqueryEasyUI框架的Web控制器基類 3 /// </summary> 4 public abstract class AbstractJqueryController : AbstractController, IToJqueryEasyUIJson 5 { 6 private string _txtJson; 7 8 public string TxtJson 9 { 10 get { return _txtJson; } 11 set { _txtJson = value; } 12 } 13 14 #region IController2 成員 15 16 public string FilterJson(string json) 17 { 18 throw new NotImplementedException(); 19 } 20 21 public string ToJson(object model) 22 { 23 string value = JavaScriptConvert.SerializeObject(model, new AspNetDateTimeConverter()); 24 return value; 25 } 26 27 public string ToJson(System.Data.DataTable dt) 28 { 29 string value = JavaScriptConvert.SerializeObject(dt); 30 return value; 31 } 32 33 public string ToJson(System.Collections.Hashtable hash) 34 { 35 string value = JavaScriptConvert.SerializeObject(hash, new AspNetDateTimeConverter()); 36 return value; 37 } 38 39 public string ToGridJson(string rowsjson, int totalCount) 40 { 41 return ToGridJson(rowsjson, null, totalCount); 42 } 43 44 public string ToGridJson(string rowsjson, string footjson, int totalCount) 45 { 46 if (footjson == null) 47 return "{\"total\":" + totalCount + ",\"rows\":" + rowsjson + "}"; 48 else 49 return "{\"total\":" + totalCount + ",\"rows\":" + rowsjson + ",\"footer\":" + footjson + "}"; 50 } 51 52 public string ToGridJson(System.Data.DataTable dt) 53 { 54 return ToGridJson(dt, -1, null); 55 } 56 57 public string ToGridJson(System.Data.DataTable dt, int totalCount) 58 { 59 return ToGridJson(dt, totalCount, null); 60 } 61 62 public string ToGridJson(System.Data.DataTable dt, int totalCount, System.Collections.Hashtable[] footers) 63 { 64 totalCount = totalCount == -1 ?

開發一個新界面框架的Web控制器，必定要先設計好數據轉換接口，由於到時候繼承它的全部控制器都會使用這些封裝的方法進行數據轉換，到時候再改動此接口影響的代碼就多啦；
還有就是TxtJson這個屬性，系統就是把此屬性中的數據輸出到界面上的；
爲何要再EFW框架中默認使用JqueryEasyUI了，最主要的是學習成本底，基本上花的幾個小時屬性一下Demo中的控件就會用了；還有就是它是基於Jquery開發的，因此本身也能夠再基礎上進行一些擴展開發，可以知足一些特殊的需求；剛開始項目中是用的Extjs開發，就是由於學習成本過高了，一個新手一開始根本摸不到邊，特別是設計界面與操做數據都是用JS代碼，代碼編寫得規範的還好，編寫得很差的，真的是太難看了；而我選擇JqueryeasyUI另外一點就是設計界面不用js代碼，用html標籤代碼就能夠搞定，很是方便；
6.Web經常使用組件封裝成控制器
Web系統中一些經常使用到的組件也封裝成獨立的控制器方便使用：
1）調試控制器DebugController
