我已经创建了一个访问者组,我正在尝试将一个类注入其中。我将所有类都连接起来并在我将其注入块中的网站中正常运行。
当我在CMS中打开访问者组标签时,出现以下异常:
StructureMap异常代码:202没有定义默认实例 PluginFamily EPiServer.ServiceLocation.ServiceAccessor`1 [Bennetts.Site.Community.Membership.IMemberFactory, Bennetts.Site.Community,Version = 1.0.0.0,Culture = neutral, PublicKeyToken = null]],EPiServer.Framework,Version = 7.0.859.16, Culture = neutral,PublicKeyToken = 8fe83dea738b45b7
站点DependencyResolverInitialization模块中的代码是:
public void ConfigureContainer(ServiceConfigurationContext context)
{
.......
context.Container.Configure(x =>
{
x.For<IMemberFactory>()
.Use<MemberFactory>()
.Ctor<string>("serviceHostname")
.Is(i => i.GetInstance<IConfigurationSettings>().GetExternalCmsServiceHostname())
.Ctor<int>("ServicePort")
.Is(i => i.GetInstance<IConfigurationSettings>().GetExternalCmsServicePort());
});
}
标准是:
public class IsMemberCriterion : CriterionBase<IsMemberCriterionSettings>
{
public Injected<IMemberFactory> MemberFactory { get; set; }
public override bool IsMatch(IPrincipal principal, HttpContextBase httpContext)
{
return MemberFactory.Service.GetMember(principal.Identity.Name) != null;
}
}
我怀疑问题是模块区域有自己的StructureMap容器。是这样的吗?如果是这样,那么确保映射的最佳方法是什么?
答案 0 :(得分:1)
答案可能为时已晚:)
使用Injected属性会更棘手。您必须告诉EPiServer应该如何创建该接口实现。这可以使用ServiceConfiguration
属性:
[ServiceConfiguration(Lifecycle = ServiceInstanceScope.Unique, ServiceType = typeof(IMemberFactory))]
public class DefaultMemberFactory : IMemberFactory
{
}
