• Spring.NET教程(十七)——整合NHibernate和ASP.NET MVC(基础篇)


     ASP.NET MVC Framework是微软官方提供的MVC模式编写ASP.NET Web应用程序的一个框架。MVC(Model-View-Controller)用于表示一种软件架构模式.它把软件系统分为三个基本部分:模型(Model),视图(View)和控制器(Controller)。

     今天带给大家的就是期待以久的ASP.NET MVC与Spring.NET和NHibernate的组合,视图打造.NET版的SSH(Spring-Struts-Hibernate)。是不是听到名字都很兴奋?我认为目前的ASP.NET MVC比Struts在某些功能上要好用的多,而且代码量要少,这就是我一直热衷于ASP.NET MVC的原因。

      我们接着昨天的例子学习。昨天我们成功测试了带事务的业务层。接下来就是将业务层的对象注入到Controller中。我们先在Controller中写好要注入的属性。

      HomeController

        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();
            }
         }

      我们知道,对Controller依赖注入需要新建一个ControllerFactory。我们实现System.Web.Mvc.IControllerFactory接口即可。实际上就是替换现有的ControllerFactory,让Spring.NET容器管理Controller。包含Spring.NET容器配置的Controller使用新建的ControllerFactory,没有包含Spring.NET容器配置的Controller使用原有的DefaultControllerFactory。

      SpringControllerFactory

    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

        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";
                //查找是否配置该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方法下增加一些代码,注册SpringControllerFactory类。

      Global.asax.cs

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

      然后我们以HomeController为例,增加一些方法。

      HomeController

    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();
            }

    Controllers.xml

    <?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>

      这里的HomeController我们部署了非singleton模式。

      最后我们配置Web.config。我总结了一下,有两个要注意的地方:

      1.需要在appSettings节点处配置SessionFactory的id

      2.需要配置httpModules,因为这关系到SessionFactory的作用域,直接影响对象的“延迟加载”等一系列问题。实际上SessionFactory的开关有Spring.Data.NHibernate.LocalSessionFactoryObject来控制。实现原理是Spring.NET会在HttpApplication.BeginRequest的事件中注册打开SessionScope的动作,并在HttpApplication.EndRequest的事件中注册关闭SessionScope的动作。这就意味着SessionFactory完全由Spring.NET来管理,我们不需要使用using语句来强制关闭Session。

      Web.config

    <?xml version="1.0"?>
