我在测试时经常遇到这个错误。我甚至无法创建一个应该返回RoleRepository的IRoleRepository实例。StructureMap配置否插件定义的异常代码202
以下是错误：
TestCase的 'EStudy.Repository.Tests.when_fetching_instance_of_role_repository_using_structuremap.should_fetch_successfully' 失败：StructureMap.StructureMapException：StructureMap异常代码：202 为PluginFamily EStudy.Domain.Model没有定义默认实例。 Model.EStudyModelDataContext，EStudy.Domain.Model，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null at StructureMap.BuildSession。 < .ctor> b__0（T型） 在StructureMap.Util.Cache 2.get_Item(KEY key) at StructureMap.BuildSession.CreateInstance(Type pluginType) at StructureMap.Pipeline.DefaultInstance.build(Type pluginType, BuildSession session) at StructureMap.Pipeline.Instance.createRawObject(Type pluginType, BuildSession session) at StructureMap.Pipeline.Instance.Build(Type pluginType, BuildSession session) at StructureMap.Pipeline.ConfiguredInstanceBase 1.getChild（字符串propertyName的，类型pluginType，BuildSession buildSession） 在StructureMap.Pipeline.ConfiguredInstanceBase 1.StructureMap.Pipeline.IConfiguredInstance.GetChild(String propertyName, Type pluginType, BuildSession buildSession) at EStudyDomainModelRepositoriesRoleRepositoryInstanceBuilder4c713d65fe464f4792cd90352224a54b.BuildInstance(IConfiguredInstance , BuildSession) at StructureMap.Pipeline.ConfiguredInstanceBase 1.StructureMap.Pipeline.IConfiguredInstance.Build（类型pluginType ，BuildSession会议，InstanceBuilder建设者） 在StructureMap.Pipeline.ConfiguredInstanceBase 1.build(Type pluginType, BuildSession session) at StructureMap.Pipeline.Instance.createRawObject(Type pluginType, BuildSession session) at StructureMap.Pipeline.Instance.Build(Type pluginType, BuildSession session) at StructureMap.Pipeline.BuildPolicy.Build(BuildSession buildSession, Type pluginType, Instance instance) at StructureMap.InstanceFactory.Build(BuildSession session, Instance instance) at StructureMap.BuildSession.CreateInstance(Type pluginType, Instance instance) at StructureMap.BuildSession.<.ctor>b__0(Type t) at StructureMap.Util.Cache 2.get_Item（琴键） 在StructureMap.BuildSession.CreateInstance（类型pluginType） 在StructureMap.Container.GetInstance（类型pluginType） 在StructureMap.Container。 GetInstanceT at StructureMap.ObjectFactory.GetInstancePLUGINTYPE C：\ Projects \ EStudyVS2008 \ EStudySoltution \ EStudy.Repository.Tests \ Te st_StructureMapConfiguration.cs（41,0）：在EStudy.Repository.Tests.when_fetching_instance_of_role_repository_using_structuremap.should_fetch_successfully（）
