Ninject 与 WCF 和拦截（用于 AOP）

发布于 2024-12-20 22:33:05 字数 1814 浏览 1 评论 0原文

我一直在尝试让ninject在wcf中工作，使用wcf扩展和使用dynamicproxy2扩展进行拦截。我基本上已经创建了一个时间属性，并使其在基本场景中正常工作。我遇到麻烦的是，在 ninject 模块中，我使用构造函数参数创建服务绑定时：

Bind<IMyDependency>().To<MyDependency>();
Bind<IService1>().To<Service1>().WithConstructorArgument("dependency", Kernel.Get<IMyDependency>());

一切正常，但 Time 属性不会在 Service1 或 MyDependency 中的任何内容上触发。

时间属性是网上流传的标准属性。唯一的其他代码实际上是 CreateKernel 方法，即 global.asax，它看起来像这样：

protected override IKernel CreateKernel() {
    IKernel kernel = new StandardKernel(
        new NinjectSettings() { LoadExtensions = false }, 
        new WcfNinjectModule(), 
        new DynamicProxy2Module()
    );
    return kernel;
}

感谢您的帮助！

编辑 12/12/2011：根据要求，我在下面添加了一些更多详细信息：整个wcf ninject模块：

public class WcfNinjectModule : NinjectModule
{

    public override void Load()
    {
        Bind<IMyDependency>().To<MyDependency>();
        Bind<IService1>().To<Service1>();
    }
}

上面是global.asax中的create kernel方法，global.asax继承自NinjectWcfApplication。

服务方法如下所示：

public class Service1 : IService1
{
    private IMyDependency _dependency;

    public Service1()
    {
    }
    public Service1(IMyDependency dependency)
    {
        _dependency = dependency;
    }

    [Time]
    public virtual string GetData(string value)
    {
        return string.Format(_dependency.GetMyString(), value);
    }
}
public interface IMyDependency
{
    string GetMyString();
}

public class MyDependency : IMyDependency
{
    [Time]
    public virtual string GetMyString()
    {
        return "Hello {0}";
    }
}

这有帮助吗？

由于删除了“WithConstructor”参数，时间截取属性将在 GetMyString 上触发，但不会在 GetData 上触发。

I've been trying to get the ninject working in wcf, using the wcf extension and the interception with dynamicproxy2 extension. I've basically created a Time attribute and have it all working in a basic scenario. Where I get trouble is when in ninject module I create my service binding with a constructor argument:

Bind<IMyDependency>().To<MyDependency>();
Bind<IService1>().To<Service1>().WithConstructorArgument("dependency", Kernel.Get<IMyDependency>());

Everything works fine, but the Time attribute wont fire on anything in my Service1 or MyDependency.

The time attribute is the standard one floating all over the internet. The only other piece of code really is the CreateKernel method is the global.asax, which looks like this:

protected override IKernel CreateKernel() {
    IKernel kernel = new StandardKernel(
        new NinjectSettings() { LoadExtensions = false }, 
        new WcfNinjectModule(), 
        new DynamicProxy2Module()
    );
    return kernel;
}

Thanks for any help!

EDIT 12/12/2011: As requested, I've added some more detail below:
The entire wcf ninject module:

public class WcfNinjectModule : NinjectModule
{

    public override void Load()
    {
        Bind<IMyDependency>().To<MyDependency>();
        Bind<IService1>().To<Service1>();
    }
}

The create kernel method in the global.asax is above, and the global.asax inherits from NinjectWcfApplication.

Service method looks like this:

public class Service1 : IService1
{
    private IMyDependency _dependency;

    public Service1()
    {
    }
    public Service1(IMyDependency dependency)
    {
        _dependency = dependency;
    }

    [Time]
    public virtual string GetData(string value)
    {
        return string.Format(_dependency.GetMyString(), value);
    }
}
public interface IMyDependency
{
    string GetMyString();
}

public class MyDependency : IMyDependency
{
    [Time]
    public virtual string GetMyString()
    {
        return "Hello {0}";
    }
}

Does this help?

Since removing the 'WithConstructor' argument, the time intercept attribute will fire on GetMyString but not on GetData.
