I would inject the IMappingEngine into the controller, instead of the using the static Mapper class. You then get all the benefits of being able to mock this in your tests.

Take a look at this link by AutoMapper's creator,

blocks|key|2807128|text|这就是我在一个项目中所做的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2807129|public+interface+IBuilder<TEntity,+TInput>
{
++++TInput+BuildInput(TEntity+entity);
++++TEntity+BuildEntity(TInput+input);
++++TInput+RebuildInput(TInput+input);
}|code-block|syntax|javascript|2807130|为每个实体或/和某些实体组实现此接口，您可以创建一个通用接口并在每个控制器中使用它；使用IoC；|2807131|您将映射代码放在前两个方法中(与映射技术无关，您甚至可以手动完成)，RebuildInput用于当您获得ModelState.IsValid+==+false时，只需再次调用BuildEntity和BuildInput即可。|2807132|以及在控制器中的用法：|2807133|++++++++public+ActionResult+Create()
++++++++{
++++++++++++return+View(builder.BuildInput(new+TEntity()));
++++++++}

++++++++[HttpPost]
++++++++public+ActionResult+Create(TInput+o)
++++++++{
++++++++++++if+(!ModelState.IsValid)
++++++++++++++++return+View(builder.RebuildInput(o));
++++++++++++repo.Insert(builder.BuilEntity(o));
++++++++++++return+RedirectToAction("index");
++++++++}|2807134|实际上，我有时会使用泛型控制器，它用于更多的实体，比如：asp.net+mvc+generic+controller|offset|length|2807135|EDIT:您可以在下面的asp.net+mvc示例应用程序中看到这种技术：http://prodinner.codeplex.com|style|BOLD|2807136|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/3413626/asp-net-mvc-generic-controller/3418849#3418849|1|http://prodinner.codeplex.com/^0|0|0|0|0|0|0|S|U|0|0|0|5|11|T|1|0^^$0|@$1|2|3|4|5|6|7|16|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|17|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|18|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|19|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|1A|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|1B|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|1C|8|@]|9|@$Q|1D|R|1E|1|1F]]|A|$]]|$1|S|3|T|5|6|7|1G|8|@$Q|1H|R|1I|U|V]]|9|@$Q|1J|R|1K|1|1L]]|A|$]]|$1|W|3|-4|5|6|7|1M|8|@]|9|@]|A|$]]]|X|$Y|$5|Z|10|11|A|$12|13]]|14|$5|Z|10|11|A|$12|15]]]]

that's how I was doing in a project:

<pre><code>public interface IBuilder&lt;TEntity, TInput&gt;
{
 TInput BuildInput(TEntity entity);
 TEntity BuildEntity(TInput input);
 TInput RebuildInput(TInput input);
}
</code></pre>

implement this interface for each entity or/and for some group of entities you could do a generic one and use it in each controller; use IoC;

you put your mapping code in the first 2 methods (doesn't matter the mapping technology, you could even do it by hand)
and the RebuildInput is for when you get the ModelState.IsValid == false, just call BuildEntity and BuildInput again.

and the usage in the controller:

<pre><code> public ActionResult Create()
 {
 return View(builder.BuildInput(new TEntity()));
 }

 [HttpPost]
 public ActionResult Create(TInput o)
 {
 if (!ModelState.IsValid)
 return View(builder.RebuildInput(o));
 repo.Insert(builder.BuilEntity(o));
 return RedirectToAction("index");
 }
</code></pre>

I actually do sometimes generic controller that is used for more entities
like here: <a href="https://stackoverflow.com/questions/3413626/asp-net-mvc-generic-controller/3418849#3418849">asp.net mvc generic controller</a>

EDIT:
you can see this technique in an asp.net mvc sample application here: 
<a href="http://prodinner.codeplex.com" rel="nofollow noreferrer">http://prodinner.codeplex.com</a>

I'm wondering about a "best practice" using NHibernate, AutoMapper and ASP.NET MVC. Currently, i'm using :

<pre><code>class Entity
{
 public int Id { get; set; }
 public string Label { get; set; }
}

class Model
{
 public int Id { get; set; }
 public string Label { get; set; }
}
</code></pre>

Entity and model are mapped like this :

<pre><code>Mapper.CreateMap&lt;Entity,Model&gt;();
Mapper.CreateMap&lt;Model,Entity&gt;()
 .ConstructUsing( m =&gt; m.Id == 0 ? new Entity() : Repository.Get( m.Id ) );
</code></pre>

And in the controller : 

<pre><code>public ActionResult Update( Model mdl )
{
 // IMappingEngine is injected into the controller
 var entity = this.mappingEngine.Map&lt;Model,Entity&gt;( mdl );

 Repository.Save( entity );

 return View(mdl);
} 
</code></pre>

Is this correct, or can it be improved ?
