ASP.NET MVC3 - 单独程序集中的区域

Question

我正在尝试使用区域设置MVC3解决方案,但我希望将我的区域放在不同的程序集中.例如,我想要一个包含母版页,样式表,脚本,登录页面等共享资源的父程序集.但我想在不同的程序集中使用不同的业务功能区域.

我尝试了为MVC2预览编写的示例:http: //msdn.microsoft.com/en-us/library/ee307987%28VS.100%29.aspx.(注意,我最初从这个Stack Overflow线程中找到了这个: ASP.NET MVC - 分离大型应用程序).但似乎MVC3没有将视图文件移动到主项目中的选项.我对使用嵌入式资源/ VirtualPathProvider选项并不感到高兴.

有关如何使用MVC3的任何建议？

谢谢,跳过

Answer 1

1 - 将你的Mvc区域分成不同的Mvc项目,编译成他们自己的单独组件

2 - 将其添加到AssemblyInfo.cs类,以在加载应用程序时调用方法

[assembly: PreApplicationStartMethod(typeof(PluginAreaBootstrapper), "Init")]

3 - 这是在加载过程中调用Init方法时的样子

public class PluginAreaBootstrapper
{
    public static readonly List<Assembly> PluginAssemblies = new List<Assembly>();

    public static List<string> PluginNames()
    {
        return PluginAssemblies.Select(
            pluginAssembly => pluginAssembly.GetName().Name)
            .ToList();
    }

    public static void Init()
    {
        var fullPluginPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Areas");

        foreach (var file in Directory.EnumerateFiles(fullPluginPath, "*Plugin*.dll"))
            PluginAssemblies.Add(Assembly.LoadFile(file));

        PluginAssemblies.ForEach(BuildManager.AddReferencedAssembly);
    }
}

4 - 添加自定义RazorViewEngine

public class PluginRazorViewEngine : RazorViewEngine
{
    public PluginRazorViewEngine()
    {
        AreaMasterLocationFormats = new[]
        {
            "~/Areas/{2}/Views/{1}/{0}.cshtml",
            "~/Areas/{2}/Views/{1}/{0}.vbhtml",
            "~/Areas/{2}/Views/Shared/{0}.cshtml",
            "~/Areas/{2}/Views/Shared/{0}.vbhtml"
        };

        AreaPartialViewLocationFormats = new[]
        {
            "~/Areas/{2}/Views/{1}/{0}.cshtml",
            "~/Areas/{2}/Views/{1}/{0}.vbhtml",
            "~/Areas/{2}/Views/Shared/{0}.cshtml",
            "~/Areas/{2}/Views/Shared/{0}.vbhtml"
        };

        var areaViewAndPartialViewLocationFormats = new List<string>
        {
            "~/Areas/{2}/Views/{1}/{0}.cshtml",
            "~/Areas/{2}/Views/{1}/{0}.vbhtml",
            "~/Areas/{2}/Views/Shared/{0}.cshtml",
            "~/Areas/{2}/Views/Shared/{0}.vbhtml"
        };

        var partialViewLocationFormats = new List<string>
        {
            "~/Views/{1}/{0}.cshtml",
            "~/Views/{1}/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml",
            "~/Views/Shared/{0}.vbhtml"
        };

        var masterLocationFormats = new List<string>
        {
            "~/Views/{1}/{0}.cshtml",
            "~/Views/{1}/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml",
            "~/Views/Shared/{0}.vbhtml"
        };

        foreach (var plugin in PluginAreaBootstrapper.PluginNames())
        {
            masterLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/{1}/{0}.cshtml");
            masterLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/{1}/{0}.vbhtml");
            masterLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/Shared/{1}/{0}.cshtml");
            masterLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/Shared/{1}/{0}.vbhtml");

            partialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/{1}/{0}.cshtml");
            partialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/{1}/{0}.vbhtml");
            partialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/Shared/{0}.cshtml");
            partialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/Shared/{0}.vbhtml");

            areaViewAndPartialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/{1}/{0}.cshtml");
            areaViewAndPartialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Views/{1}/{0}.vbhtml");
            areaViewAndPartialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Areas/{2}/Views/{1}/{0}.cshtml");
            areaViewAndPartialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Areas/{2}/Views/{1}/{0}.vbhtml");
            areaViewAndPartialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Areas/{2}/Views/Shared/{0}.cshtml");
            areaViewAndPartialViewLocationFormats.Add(
                "~/Areas/" + plugin + "/Areas/{2}/Views/Shared/{0}.vbhtml");
        }

        ViewLocationFormats = partialViewLocationFormats.ToArray();
        MasterLocationFormats = masterLocationFormats.ToArray();
        PartialViewLocationFormats = partialViewLocationFormats.ToArray();
        AreaPartialViewLocationFormats = areaViewAndPartialViewLocationFormats.ToArray();
        AreaViewLocationFormats = areaViewAndPartialViewLocationFormats.ToArray();
    }
}

5 - 从您的不同Mvc(区域)项目注册您的区域

namespace MvcApplication8.Web.MyPlugin1
{
    public class MyPlugin1AreaRegistration : AreaRegistration
    {
        public override string AreaName
        {
            get { return "MyPlugin1"; }
        }

        public override void RegisterArea(AreaRegistrationContext context)
        {
            context.MapRoute(
                "MyPlugin1_default",
                "MyPlugin1/{controller}/{action}/{id}",
                new {action = "Index", id = UrlParameter.Optional}
                );
        }
    }
}

Answer 2

您可以在不使用区域的情况下分离控制器和视图。对于控制器，您可以使用 Windsor 或任何其他 IoC 容器来解析来自不同程序集的控制器。例如，您可以通过以下方式注册所有控制器：

container.Register(AllTypes.FromAssemblyInDirectory(new AssemblyFilter(HttpRuntime.BinDirectory)).BasedOn<IController>().Configure(c => c.LifeStyle.Transient));

此外，您还必须实现 IDependencyResolver 然后设置 DependencyResolver.SetResolver(...)。

对于视图，您有两种选择：

1. 嵌入式资源和 VirtualPathProvider
2. 构建/部署后简单地将视图文件复制到适当的位置

我们使用 Windsor 和 VirutalPathProvider 实现提供的嵌入式资源视图构建了一个简单的框架（类似于 Portable Areas）。
