使用StructureMap / ASP.MVC / Visual Studio / LinqToSql的奇怪行为

我最近一直在使用带有StructureMap的新MVC框架并且总体上已经取得了很好的结果，但是，我一直遇到一个我无法理解的非常奇怪的错误或者解决了如何解决。

这是我的架构：

  • DBContext - linqToSql数据上下文。
  • IRepository - 定义数据方法的合同。
  • IService - 定义服务方法的合同。
  • 控制器 - 本例中为两个。
因此，我有：

public class Repo : IRepository
{
    public Repo(DBContext db)
    {
       .....
    }
}

public class Service : IService
{
    public Service(IRepository repo)
    {
       .....
    }
}

public class ControllerOne : Controller
{
    public ControllerOne(IService service)
    {
       .....
    }
}

public class ControllerTwo : Controller
{
    public ControllerTwo(IService service)
    {
       .....
    }
}

StructureMap用于定义IRepository和IService的具体类型，DBContext由lamba表达式构成 - （）=＆gt;由DSL注册表配置的新DBContext（）。

目前没有DBContext的缓存

解决问题：

我的索引页面加载并同时向ControllerOne和ControllerTwo发出两个Ajax请求，这些请求是通过MvcContrib的StructureMap控制器工厂构建的。

StructureMap正在注入IService的具体类型，而IService又是使用配置的IRepository实例和新的DBContext对象创建的。

ControllerOne正在从IService实例请求一个模型，然后将其作为JsonActionResult返回，该模型由Newtonsoft.Json呈现。

ControllerTwo正在从IService实例请求一个不同的模型，当MVC框架执行ActionResult时，它也被序列化为Json对象。

我在VS2008中通过Cassini运行网站。

我不时会看到的问题是LinqToSql内部生成的错误

  • 数据无法读取，已经有读者打开或
  • 无法将数据加载到数据表中，因为数据已经存在（我目前没有确切的例外情况，但两者都是LinqToSql内部的。）

如果ControllerOne中发生错误，那么ControllerTwo也会因类似错误而失败，就好像这两个请求正在运行共享对象一样。

它不会一直出错，但它足以让我担心我的架构，并且它在某种程度上配置错误。

结构映射是否有可能在后续请求中返回相同的ControllerOne和ControllerTwo实例，或者它是否以任何方式缓存DBContext？即使我不是要求它？

在Visual Studio / Cassini中工作时有没有人见过类似的东西？通过IIS有帮助吗？

我应该删除LinqToSql吗？

关闭Visual Studio并再次打开通常可以解决问题一段时间。

非常感谢，如果有人能够解决这个问题。

4 个答案:

答案 0 :(得分：6)

我正在和Jeremy Miller谈论这件事，而你不希望用SM来管理数据库上下文的生命周期 - 让repo根据需要进行实例化。这会给你如何进行对象更新/持久化提出问题（如果你依赖于一个多个请求保持活动的上下文），但不依赖于web应用程序是值得的。

由于这样的原因，我不得不从店面中删除db上下文管理的东西 - 我得到了内存泄漏。我不会说这是SM的错 - 但总的来说只是让回购开启一个新的背景。

答案 1 :(得分：2)

在ASP.NET MVC中使用DI容器时的一个常见错误是许多DI容器默认为Singleton模式。我不知道这是不是这样，但你应该仔细检查。 ASP.NET MVC要求在每个请求上创建控制器，因为它具有每请求状态和上下文。

答案 2 :(得分：1)

添加：

MultipleActiveResultSets=True

到连接字符串的末尾（假设MSSQL 2005 +）

为您的linq上下文执行此操作：打开属性选项卡 - ＆gt;展开连接 - ＆gt;点击“连接字符串”上的“...” - ＆gt; '高级' - ＆gt; 'MultipleActiveResultSets' - ＆gt;真。

我今天自己解决了这个问题，我的架构几乎完全相同（除了结构图而不是结构图）。包括通过JS加载的两个控制器！

答案 3 :(得分：1)

您是否完全确定对象层次结构中没有任何内容正在缓存/或具有生命周期配置？我有一个带有配置的prod应用程序，就像这样：

    ForRequestedType<SomeDataContext>().TheDefault.Is.ConstructedBy(
        () => new SomeDataContext(someConnString);

它没有使用asp.net MVC。关于范围问题，如果你还没有设置任何东西，结构图将默认为PerRequest（不是asp.net请求，而是结构映射请求，就像每个.GetInstance调用一样） - http://structuremap.sourceforge.net/Scoping.htm。如果你对没有配置影响它是肯定的，那么看看mvc contrib或其他东西是否可能重用实例。

关于发布的例外信息。该错误涉及操作结果，操作结果过滤器，json序列化，自定义方法以及由于意外null而导致一个linq2sql调用失败的组合。这是许多不同作品的组合，其中一些我不知道。我会更安全地运行计算内容（调用linq2sql），当序列化到其他不涉及json序列化/操作结果片段的地方时调用。这只是一个疯狂的猜测，因为我不知道这些作品是如何/什么时候被调用的，以及他们内部采取了什么类型的行动。
