Spring.NET學習筆記19——整合NHibernate和ASP.NET MVC(基礎篇)

　　ASP.NET MVC Framework是微軟官方提供的MVC模式編寫ASP.NET Web應用程序的一個框架。MVC(Model-View-Controller)用於表示一種軟件架構模式.它把軟件系統分爲三個基本部分:模型(Model),視圖(View)和控制器(Controller)。

　　今天帶給大家的就是期待以久的ASP.NET MVC與Spring.NET和NHibernate的組合，視圖打造.NET版的SSH(Spring-Struts-Hibernate)。是不是聽到名字都很興奮？我認爲目前的ASP.NET MVC比Struts在某些功能上要好用的多，而且代碼量要少，這就是我一直熱衷於ASP.NET MVC的原因。

　　我們接着昨天的例子學習。昨天我們成功測試了帶事務的業務層。接下來就是將業務層的對象注入到Controller中。我們先在Controller中寫好要注入的屬性。

　我們知道，對Controller依賴注入需要新建一個ControllerFactory。我們實現System.Web.Mvc.IControllerFactory接口即可。實際上就是替換現有的ControllerFactory，讓Spring.NET容器管理Controller。包含Spring.NET容器配置的Controller使用新建的ControllerFactory，沒有包含Spring.NET容器配置的Controller使用原有的DefaultControllerFactory。

/* * 劉冬博客園 * www.cnblogs.com/GoodHelper */ using System; using System.Collections.Generic; using System.Linq; using System.Web; using Spring.Context; using Spring.Context.Support; using System.Web.Mvc; namespace Controllers { /// <summary> /// Spring.NET ControllerFacotry /// </summary> public class SpringControllerFactory : IControllerFactory { /// <summary> /// Default ControllerFactory /// </summary> private static DefaultControllerFactory defalutf = null; public IController CreateController(System.Web.Routing.RequestContext requestContext, string controllerName) { //get spring context WebApplicationContext ctx = ContextRegistry.GetContext() as WebApplicationContext; string controller = controllerName + "Controller"; //查找是否配置該Controller if (ctx.ContainsObject(controller)) { object controllerf = ctx.GetObject(controller); return (IController)controllerf; } else { if (defalutf == null) { defalutf = new DefaultControllerFactory(); } return defalutf.CreateController(requestContext, controllerName); } } public void ReleaseController(IController controller) { //get spring context IApplicationContext ctx = ContextRegistry.GetContext(); if (!ctx.ContainsObject(controller.GetType().Name)) { if (defalutf == null) { defalutf = new DefaultControllerFactory(); } defalutf.ReleaseController(controller); } } } }

　　在Global.asax.cs的Application_Start方法下增加一些代碼，註冊SpringControllerFactory類。

protected void Application_Start() { log4net.Config.XmlConfigurator.Configure(); ControllerBuilder.Current.SetControllerFactory(typeof(Controllers.SpringControllerFactory)); RegisterRoutes(RouteTable.Routes); }

然後我們以HomeController爲例，增加一些方法。

public class HomeController : Controller { public ICompanyManager CompanyManager { get; set; } public IUserManager UserManager { get; set; } public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; ViewData["Company"] = CompanyManager.LoadAll(); return View(); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult SaveUser(User user) { user.CurrentCompany = CompanyManager.Get(user.CurrentCompany.CompanyID); UserManager.Save(user); return RedirectToAction("GetCompany", "Home", new { id = user.CurrentCompany.CompanyID }); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult SaveCompany(Company company) { CompanyManager.Save(company); return RedirectToAction("Index", "Home"); } public ActionResult GetCompany(int id) { ViewData["Company"] = CompanyManager.Get(id); return View(); } public ActionResult About() { return View(); }

<?xml version="1.0" encoding="utf-8" ?> <objects xmlns="http://www.springframework.net"> <object id="HomeController" type="Controllers.HomeController, Controllers" singleton="false"> <property name="CompanyManager" ref="CompanyManager"/> <property name="UserManager" ref="UserManager"/> </object> </objects>

　　這裏的HomeController我們部署了非singleton模式。

　　最後我們配置Web.config。我總結了一下，有兩個要注意的地方：

　　1.需要在appSettings節點處配置SessionFactory的id
　　2.需要配置httpModules，因爲這關係到SessionFactory的作用域，直接影響對象的“延遲加載”等一系列問題。實際上SessionFactory的開關有Spring.Data.NHibernate.LocalSessionFactoryObject來控制。實現原理是Spring.NET會在HttpApplication.BeginRequest的事件中註冊打開SessionScope的動作，並在HttpApplication.EndRequest的事件中註冊關閉SessionScope的動作。這就意味着SessionFactory完全由Spring.NET來管理，我們不需要使用using語句來強制關閉Session。
