asp.net-mvc-4 – 从beta版升级后的Autofac / MVC4 / WebApi(RC)

基本上,使用新的包,您只需要在global.asax.cs中执行此操作：

GlobalConfiguration.Configuration.DependencyResolver = new Autofac.Integration.WebApi.AutofacWebApiDependencyResolver(container);

我刚刚遇到同样的问题 – 我能够通过创建一个简单的IDependencyResolver实现来解决它在我的情况下,包装现有的AutofacDependencyResolver.

正如类名称所示,我将其视为临时解决方案 – BeginScope和Dispose方法将需要一些工作,显然不适合于生产环境,但这允许我继续开发,直到出现正确的解决方案.

所以,有了这些注意事项,IDependencyResolver实现如下所示：

public class TemporaryDependencyResolver : IDependencyResolver
{
    private readonly AutofacDependencyResolver _autofacDependencyResolver;

    public TemporaryDependencyResolver(AutofacDependencyResolver autofacDependencyResolver)
    {
        _autofacDependencyResolver = autofacDependencyResolver;
    }

    public void Dispose()
    {
    }

    public object GetService(Type serviceType)
    {
        return _autofacDependencyResolver.GetService(serviceType);
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return _autofacDependencyResolver.GetServices(serviceType);
    }

    public IDependencyScope BeginScope()
    {
        return this;
    }
}

我在Global.asax.cs中设置了它：

var container = builder.Build();
var resolver = new AutofacDependencyResolver(container);
GlobalConfiguration.Configuration.DependencyResolver = new TemporaryDependencyResolver(resolver);
