ASP.NET MVC学习笔记3

一直使用WebForm进行开发，最近无事，决定研究一下ASP.NET MVC,现在ASP.NET MVC已经到版本2了，
ASP.NET  MVC是微软阵营中的一个新秀，我个人感觉这是微软向Java阵营伸出的橄榄枝，在这里其实完全可以
使用LinQ+ASP.NET MVC2进行开发，但出于对于SSH框架的流行，因此可以使用类似的思想ORM+Ioc:
MVC使用ASP.NET MVC 2
ORM使用的是NHibernate
NHibernate标注配置使用FluentNHibernate框架
Ioc使用微软的Unity框架，现面分别进行一些要点的讲解:
首先:NHibernate标注配置FluentNHibernate说明
普通类:
 

public class UserRolesMap:ClassMap<UserRoles>
{
    public UserRolesMap()
    {
        Id(r => r.Id);
        Map(r => r.Name);
    }
}

 外键类:

public class Users:ModelBase
{
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }
    public virtual string Address { get; set; }
    public virtual string Phone { get; set; }
    public virtual string Mail { get; set; }
    public virtual int UserStateId { get; set; }
    public virtual int IsOnLine { get; set; }
    public virtual string LoginId { get; set; }
    public virtual string LoginPwd { get; set; }
    public virtual int UserRoleId { get; set; }
    public virtual int Gender { get; set; }
    public virtual UserRoles UserRole { get; set; }
    public virtual UserStates UserState { get; set; }

    public override IEnumerable<RuleInfo> GetRules()
    {
        if (string.IsNullOrEmpty(Name))
            yield return new RuleInfo("Name", "名称不为空!");
        yield break;
    }
}

Hibernate使用说明:
SessionFactory(会话工厂):

public class SessionFactory
{
    private static ISessionFactory CurrentSessionFactory()
    {
        string connstring=System.Configuration.ConfigurationManager.ConnectionStrings["mybookshop"].ConnectionString;
        string path=HttpContext.Current.Server.MapPath("~/bin");
        return Fluently.Configure().Database(MsSqlConfiguration.MsSql2005.ConnectionString(connstring))
            .Mappings(m=>m.FluentMappings.AddFromAssembly(typeof(SessionFactory).Assembly).ExportTo(path)).BuildSessionFactory();
    }

    private static ISession session;
    public ISession Session
    {
        get
        {
            if (session == null)
                session = CurrentSessionFactory().OpenSession();
            return session;
        }
    }
}

 Web.Config中配置连接字符串

DAL类使用Ioc注入SessionFactory:

Ioc说明：
控制器中需要注入DAL:

public class UserRolesDAO
  {
      [Dependency]
      public SessionFactory Sf{get;set;}
      public IList<UserRoles> FindAll()
      {
          return Sf.Session.CreateQuery("from UserRoles r order by r.Id").List<UserRoles>();
      }

 

需要在Global.asax添加Ioc初始化处理

public class MvcApplication : System.Web.HttpApplication
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

    }

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterRoutes(RouteTable.Routes);
        InitializeContainer();
    }

    protected virtual void InitializeContainer()
    {
        IUnityContainer container = MyTools.UnityContainer;

        Type controllerType = typeof(IController);
        foreach (Type type in Assembly.GetExecutingAssembly().GetTypes())
        {
            if (controllerType.IsAssignableFrom(type))
            {
                container.RegisterType(type, type);
            }
        }
        UnityControllerFactory factory = new UnityControllerFactory(container);
        ControllerBuilder.Current.SetControllerFactory(factory);
    }

}

 

MyTools代码:

public class MyTools
{
    public static IUnityContainer UnityContainer
    {
        get
        {
            IUnityContainer unity = new UnityContainer();
            //手动Ioc注入
            return unity;
        }
    }
}

最后再说一下MVC中的验证:
创建ModelBase类(Model基类):

public class ModelBase
{

    public virtual IEnumerable<RuleInfo> GetRules()
    {
        yield break;
    }

    /// <summary>
    /// 验证
    /// </summary>
    public virtual void Validate()
    {
        if (this.GetRules().Count()>0)
            throw new ApplicationException();
    }
}

public class RuleInfo
{
    public string Name { get; set; }
    public string Msg { get; set; }
    public RuleInfo(string name, string msg)
    {
        this.Name = name;
        this.Msg = msg;
    }
}

Model类继承此类，并重写GetRules方法

public class UserRoles:ModelBase
{
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }
    public override IEnumerable<RuleInfo> GetRules()
    {
        //进行验证
        if (string.IsNullOrEmpty(Name))
            yield return new RuleInfo("Name", "名称不为空!");
        yield break;
    }
}

在DAL中使用验证:

public int Add(UserRoles r)
{
    try
    {
        r.Id = 0;
        r.Validate();//验证
        Sf.Session.Save(r);
        Sf.Session.Flush();
        return 1;
    }
    catch
    {
        return 0;
    }
}

哈哈!OK了!
