Question

我已经将Quartz设置为Windows服务（如果重要的话，使用AdoJobStore）并设法通过远程处理来添加/安排生活在我自己的项目公司中的自定义IJob的ASP.NET站点与之通信.Project.ServiceLayer。

这花了我一段时间但是我的开发机器上的所有工作都正常，前提是Windows服务文件夹和网站bin文件夹中都存在Company.Project.ServiceLayer.dll。但是，在生产环境中，需要将Company.Project.ServiceLayer.dll添加到GAC。我试图在我的开发机器上模拟这个，从services文件夹中删除Company.Project.ServiceLayer.dll并使用gacutil将其添加到GAC中。不幸的是，现在当服务启动并尝试实例化我的IJob实例时，它无法从GAC加载程序集并抛出异常“无法加载文件或程序集”（下面的完整详细信息）。

我猜测Quartz在[QRTZ_JOB_DETAILS]。[JOB_CLASS_NAME]字段中使用反射和DB值来尝试加载类？我可能完全错了但是因为这个值（“Company.Product.ServiceLayer.SchedulerJobs.QuintilesEasyJob，Company.Product.ServiceLayer”）只是该类的部分描述（它缺少版本和公钥令牌）不是意味着当.NET进行反射时，.NET不会查看GAC，因为强大的命名dll可以存在吗？这就是我的GAC设置现在失败的原因吗？ Quartz Windows服务是否可以在GAC中使用dll？

非常感谢任何帮助。

Answer 1

为此，StdAdoDelegate上有一个扩展点，可以重写方法GetStorableJobTypeName以包含版本和强名称信息。目前没有配置切换来改变行为，因此您需要扩展SqlServerDelegate（如果使用SQL Server）。

因此，你的派生类中的新版本将会是这样的：

protected override string GetStorableJobTypeName(Type jobType)
{
    return jobType.AssemblyQualifiedName;
}

默认情况下，Quartz仅使用仅具有类型和程序集名称的程序集限定名来减轻版本问题。但要注意它们，当版本信息包含在类型中时，您需要手动修复数据库数据或创建程序集版本重定向（如果DLL版本号更改）。

Answer 2

我终于自己怀疑了这个。通过在app.config中添加部分名称到完整/强名称映射，我能够获得服务以查看GAC，如下所示：

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <qualifyAssembly partialName="Company.Product.ServiceLayer" fullName="Company.Product.ServiceLayer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=125c3f237e3350e4"/>
    </assemblyBinding>
  </runtime>

Quartz.NET作为GAC中具有依赖关系的Windows服务
