Question

我有这个结构图配置和ITaskFactory for fluentScheduler。

public class StructureMapRegistry : Registry
{
    public StructureMapRegistry()
    {

        Scan(x =>
        {
            x.AssembliesFromApplicationBaseDirectory();
            x.WithDefaultConventions();
        });
        //implementace daného rozhraní naplní stejně jmenující se třídou.
        For<IPlayerService>().Use<PlayerService>().Singleton();
        For<IWorldService>().Use<WorldService>().Singleton();
        For<IQuestService>().Use<QuestService>().Singleton();
        For<IHeroesService>().Use<HeroesService>().Singleton();
        For<ISaveChangesService>().Use<SaveChangesService>().Singleton();
        For<IAddHeroesQuests>().Use<AddHeroesQuests>().Singleton();
        IncludeRegistry(new IoC());
    }
}

public class StructureMapTaskFactory : ITaskFactory
{
    public ITask GetTaskInstance<T>() where T : ITask
    {
        return ObjectFactory.Container.GetInstance<T>();
    }
}

我遇到了这个例外。

{StructureMap.StructureMapConfigurationException: No default Instance is registered and cannot be automatically determined for type 'TheGame.Tasks.IAddHeroesQuests'

There is no configuration specified for TheGame.Tasks.IAddHeroesQuests

1.) Container.GetInstance(TheGame.Tasks.IAddHeroesQuests)

   v StructureMap.SessionCache.GetDefault(Type pluginType, IPipelineGraph pipelineGraph) v c:\BuildAgent\work\996e173a8ceccdca\src\StructureMap\SessionCache.cs:řádek 63
   v StructureMap.BuildSession.GetInstance(Type pluginType) v c:\BuildAgent\work\996e173a8ceccdca\src\StructureMap\BuildSession.cs:řádek 60

   v System.Threading.Tasks.Task.InnerInvoke()
   v System.Threading.Tasks.Task.Execute()}

我不知道为什么。

依赖注入

FluentScheduler使您可以轻松使用您选择的IoC工具来创建作业实例。只需实现IJobFactory。

使用StructureMap的示例：

using FluentScheduler;
using StructureMap;

public class StructureMapJobFactory : IJobFactory
{
    public IJob GetJobInstance<T>() where T : IJob
    {
        return ObjectFactory.Container.GetInstance<T>();
    }
}

public class MyRegistry : Registry
{
    public MyRegistry()
    {
        // Schedule an IJob to run at an interval
        Schedule<MyJob>().ToRunNow().AndEvery(2).Seconds();
    }
}

使用JobManager注册新作业工厂： 这部分是你的代码。你需要告诉JobManager.JobFactory是StructuremapJobFactory，就像你说你的依赖注入器是这样。

protected void Application_Start()
{
    JobManager.JobFactory = new StructureMapJobFactory(); // THIS PART IS MISSING ON YOUR CODE
    JobManager.Initialize(new MyRegistry()); 
}

如何为fluentscheduler配置structuremap？
