EFW框架源代码下载：http://pan.baidu.com/s/1qWJjo3U
EFW框架中的WebController就是解决JqueryEasyUI与逻辑层的交互，之间的数据是通过Json字符串来传递；值得注意的是WebController的代码一定不要和EFWWeb项目放在一起，你可以单独建一个项目类库，也可以和逻辑层项目放一起；在EFWWeb项目不要编写任何C#代码，这个在前面的文章中就提过，可以让你的Web项目发布更省事一点，免去编译EFWWeb项目的痛苦；
控制器可以调用分层一下的所有代码，包括ObjectModel、Dao、Entity，甚至可以直接用oleDb编写SQL语句操作数据库；还有控制器与控制器之间是不能存在任何依赖关系的；
本章主要内容通过解读框架源代码来学习WebController是怎么实现的，以及思考这样实现会给我们开发带来什么好处；
本文要点：
1.如何使用Web控制器
2.Web控制器的设计思路
3.Web控制器基类AbstractController的实现
4.Web控制器的自定义标签WebControllerAttribute和WebMethodAttribute
5.基于JqueryEasyUI封装的Web控制器的实现
6.Web常用组件封装成控制器

EFW框架控制器设计图
1.如何使用Web控制器
讲解EFW框架中的Web控制器的使用之前先看看传统的Web系统是如何开发的；
如上图，传统方式一个aspx文件对应一个cs文件，开发方式跟Winform桌面程序相同，都是事件响应的模式；我们再看看EFW框架中是如何开放的；
如上图，有两个项目EFWWeb项目和Books项目，EFWWeb项目里面只有界面HTML代码和JS代码，后台CS代码在另外的Books项目中；接着看里面的详细代码，界面层是如何调用后台的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.WebController11 {12 [WebController]13 public class bookController : EFWCoreLib.WebFrame.Controller.AbstractJqueryController14 {15 [WebMethod]16 public void SaveBook()17 {18 Book book = GetModel<Book>();19 book.save();20 TxtJson = ReturnSuccess("保存书籍成功！");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 //创建实体对象实例36 Book book = NewObject<Book>();37 38 //1.根据id获取一条记录39 book= book.getmodel(1) as Book;40 41 //2.修改或者新增一条记录42 book.BookName = "人月神话";43 book.BuyPrice = 23;44 book.BuyDate = Convert.ToDateTime("2014-01-01");45 book.save();46 47 //3.根据id删除表数据48 book.delete(1);49 50 //4.获取表所有记录转换为List实体对象51 List<Book> booklist = book.getlist<Book>();52 53 //5.获取表所有记录转换为DataTable54 DataTable dt = book.gettable();55 }56 }57 }
我们先说Book.aspx文件，里面的代码是基于JqueryEasyUI框架编写的，实现了一个网格数据，上面有添加、修改工具栏按钮，点击按钮弹出维护界面；这些代码没有什么好讲得，等你熟悉JqueryEasyUI的相关控件后，就能很快的开发各种复杂界面；我们接着看Book.js脚本文件，是采用Jquery的方式编写javascript脚本；
界面加载后就会执行这段代码，实现网格的数据显示，给datagrid控件设置url地址就会自动向后台发送Ajax请求，请求返回的Json数据datagrid控件解析后显示在界面；重点说一下这个url的参数意思，这是通往后台控制器的桥梁；controller指定后台控制器的名称bookController，method指定控制器内的方法名SearchBook，注意名称的大小写别搞错了；
总结一下，Ajax向后台发送请求的URL必须采用Controller.aspx?controller=XXX&method=XXX这种格式，调试的时候控制器中打了断点没有进来，首先查看指定的控制器名称和方法名称是否正确；
2.Web控制器的设计思路
上文中举的实例是利用JqueryEasyUI开发的，如果我的项目不想要JqueryEasyUI，用更专业的Extjs或其他界面框架怎么办，EFW框架设计的时候充分的考虑到了这一点，我们看最上的“EFW框架控制器设计图”，bookController继承的是AbstractJqueryController对象，AbstractJqueryController对象又继承的AbstractController对象，AbstractController是Web控制器的核心基类，AbstractJqueryController就是针对JqueryEasyUI框架实现的控制器，我们要实现Extjs框架，就只要想只要像AbstractJqueryController一样编写一个适合Extjs框架的控制器基类，我们的bookController继承它就行了；
还有比如我们还开发手机上运行的网页程序，同样可以用这种方式来实现，下一个版本会把jquery.mobile引入到EFW框架中；
3.Web控制器基类AbstractController的实现
这里讲解一下Web控制器的核心基类AbstractController的代码实现；
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 GetSysLoginRight12 {13 get14 {15 if (sessionData != null && sessionData.ContainsKey("RoleUser"))16 {17 return (SysLoginRight)sessionData["RoleUser"];18 }19 else20 {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数据传入后台31 /// </summary>32 public System.Collections.Generic.Dictionary<string, Object> sessionData33 {34 get35 {36 return _sessionData;37 }38 set39 {40 _sessionData =http://www.mamicode.com/ value;41 }42 }43 44 private System.Collections.Generic.Dictionary<string, Object> _putOutData;45 /// <summary>46 /// 后台传出数据到Session数据47 /// </summary>48 public System.Collections.Generic.Dictionary<string, Object> PutOutData49 {50 get51 {52 return _putOutData;53 }54 set55 {56 _putOutData =http://www.mamicode.com/ value;57 }58 }59 60 private List<string> _clearKey;61 /// <summary>62 /// 清除Session的数据63 /// </summary>64 public List<string> ClearKey65 {66 get { return _clearKey; }67 set { _clearKey = value; }68 }69 70 private System.Collections.Generic.Dictionary<string, string> _paramsData;71 /// <summary>72 /// Url参数传递数据73 /// </summary>74 public System.Collections.Generic.Dictionary<string, string> ParamsData75 {76 get { return _paramsData; }77 set { _paramsData =http://www.mamicode.com/ value; }78 }79 80 private System.Collections.Generic.Dictionary<string, string> _formData;81 /// <summary>82 /// Form提交的数据83 /// </summary>84 public System.Collections.Generic.Dictionary<string, string> FormData85 {86 get { return _formData; }87 set { _formData =http://www.mamicode.com/ value; }88 }89 90 91 }
AbstractController基类封装了三方面的内容：
1）数据库操作对象，这个我们之前第十章也讲过为什么要在控制器开放oleDb，这也是为了让框架分层使用起来更灵活，且兼容性强；
2）系统登录用户信息SysLoginRight，此属性封装了用户登录后的姓名、部门、机构等信息；这样在控制器中查询当前登录用户的数据时候会很简单；
3）网页中的数据，如请求参数、Session数据、表单数据等；从界面传进来的数据都可以从中获取；
4.Web控制器的自定义标签WebControllerAttribute和WebMethodAttribute
为了能让系统根据url中控制器名称和方法名称找到对应的代码执行，就像Webservice服务一样需要对Web控制器的类名和方法名上加上上面两个自定义标签；
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 /// 打开数据库，中间用,号隔开 7 /// </summary> 8 public string OpenDBKeys 9 {10 get { return _openDBNames; }11 set { _openDBNames = value; }12 }13 14 string _memo;15 public string Memo16 {17 get { return _memo; }18 set { _memo = value; }19 }20 }
值得注意的就是，控制器的名称在整个系统中不能重复，如果出现相同名称的控制器，系统就可能无法正确调用对应的控制器；
5.基于JqueryEasyUI封装的Web控制器的实现
接下来讲解一下基于JqueryEasyUI封装的AbstractJqueryController的代码是如何实现的；AbstractJqueryController类继承了IToJqueryEasyUIJson接口，IToJqueryEasyUIJson接口就是提取出了把数据对象转换为符合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 /// 对象转与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);//过滤json字符串中所有特殊字符 9 10 string ToJson(object model);11 string ToJson(System.Data.DataTable dt);//转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>();//从form表单提交的数据转为实体对象38 T GetModel<T>(T model);//从form表单提交的数据赋值给model39 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);//提示后再回退51 string ToView(string info, string Url);//提示后调整到执行页面52 53 54 55 }
AbstractJqueryController文件

开发一个新界面框架的Web控制器，一定要先设计好数据转换接口，因为到时候继承它的所有控制器都会使用这些封装的方法进行数据转换，到时候再改动此接口影响的代码就多啦；
还有就是TxtJson这个属性，系统就是把此属性中的数据输出到界面上的；
为什么要再EFW框架中默认使用JqueryEasyUI了，最主要的是学习成本底，基本上花的几个小时属性一下Demo中的控件就会用了；还有就是它是基于Jquery开发的，所以自己也可以再基础上进行一些扩展开发，能够满足一些特殊的需求；刚开始项目中是用的Extjs开发，就是因为学习成本太高了，一个新手一开始根本摸不到边，特别是设计界面与操作数据都是用JS代码，代码编写得规范的还好，编写得不好的，真的是太难看了；而我选择JqueryeasyUI另一点就是设计界面不用js代码，用html标签代码就可以搞定，非常方便；
6.Web常用组件封装成控制器
Web系统中一些常用到的组件也封装成独立的控制器方便使用：
1）调试控制器DebugController
